We engineercriticaldigital systems.
Operations platforms, security architecture and Palantir Foundry delivery for organisations where a wrong answer stops the business.
- Focus Systems that cannot fail quietly
- Security Designed in, not audited on
- Based Vilnius, Lithuania · working across Europe and the United Kingdom
01What we are for
Built for systemsthat cannot failquietly.
Most software can afford an outage. Some cannot — because operations stop, money moves incorrectly, or someone gets the wrong answer at the wrong moment. That is the category we work in.
- 01
Enterprise-grade engineering
Senior engineers who have run systems in production, not a delivery pyramid with one architect at the top.
- 02
Security built into architecture
Threat modelling during design, authorisation as domain logic, and remediation sequenced by real exploitability.
- 03
Scalable system design
Boundaries, data models and integration patterns chosen for the load and the change rate the business actually has.
- 04
Data-driven delivery
Progress measured in working increments in a production-like environment, not in percentage-complete reports.
- 05
Long-term technical partnership
We hand over documentation, reasoning and skills, so you are not structurally dependent on us.
03Services
Nine services.One standard.
Each service exists because a specific class of problem keeps arriving. Below is what each one solves, how we approach it, and what changes for the business afterwards.
- 01Enterprise Software DevelopmentLong-lived business systems built around an explicit domain model, with the operational and security properties an enterprise needs from day one.
- Business problem
- Core business systems accumulate undocumented behaviour, brittle integrations and unclear ownership. Change becomes slow and risky, and the cost of every new requirement rises.
- What BYAK does
- We start from the domain and the operational constraints, define an explicit architecture, and deliver in vertical slices that reach production early and stay releasable.
- Business outcome
- A system your team can extend without fear, with the reliability, auditability and security characteristics the business actually requires.
- Domain-driven design and event modelling
- Distributed system and service boundary design
- Relational and document data modelling
- Event-driven and message-based architecture
- API design: REST, gRPC and GraphQL
- 02Mobile Application DevelopmentNative and cross-platform applications for workforces and customers, built to work under poor connectivity and enterprise device policy.
- Business problem
- Mobile projects are often scoped as a smaller version of the web product, then fail on the things that are specific to mobile: offline behaviour, background sync, device management, store review and long-term OS churn.
- What BYAK does
- We design the synchronisation and security model first, then build against real device and network conditions, with release engineering set up from the first build.
- Business outcome
- An application people can actually use where the work happens, and a release process your team can run without us.
- Native iOS and Android development
- Cross-platform delivery where it is the right trade-off
- Offline-first data architecture and conflict resolution
- Background processing and push notification design
- Biometric and certificate-based authentication
- 03Cybersecurity ConsultingSecurity embedded in architecture and delivery: threat modelling, secure design review, and practical remediation your engineers can execute.
- Business problem
- Security arrives as a report at the end of a project. The findings are real, the deadline is fixed, and the team ships anyway with a list of accepted risks that never gets closed.
- What BYAK does
- We embed security into design and delivery: threat modelling while the architecture is still soft, authorisation designed as a first-class part of the domain, and remediation sequenced by exploitability and business impact.
- Business outcome
- Fewer findings late, a shorter path from finding to fix, and an engineering team that can reason about its own threat surface.
- Threat modelling (STRIDE and attack-tree based)
- Application and API security architecture
- Identity, authentication and authorisation design
- Cloud security architecture and configuration review
- Secrets management and key handling
- 04Security Audits & Vulnerability AssessmentsEvidence-based assessment of applications, APIs, cloud configuration and architecture, with findings written so they can be fixed.
- Business problem
- Automated scans produce volume, not clarity. Teams receive hundreds of findings without exploitability context, business impact or a realistic fix, and the important issues get lost.
- What BYAK does
- Manual, architecture-aware assessment supported by tooling. Every finding is reproduced, rated for exploitability and business impact, and paired with a specific remediation.
- Business outcome
- A short, ordered list of what to fix first, evidence you can show a customer or auditor, and a re-test that confirms the fix.
- Web application and API assessment
- Authentication and session management review
- Authorisation and access-control testing
- Cloud configuration and IAM review
- Infrastructure-as-code review
- 05Palantir Foundry Development & ConsultingOntology design, pipeline engineering, operational applications and enablement for organisations delivering on Palantir Foundry.
- Business problem
- Foundry programmes often stall between data integration and operational use. Pipelines land, dashboards appear, and the decisions the platform was bought to improve still happen in spreadsheets.
- What BYAK does
- We treat the ontology as the product: a shared operational model of the business, connected to real workflows and writeback, with the pipelines and governance to keep it trustworthy.
- Business outcome
- Decisions made inside the platform, against data the business trusts, by people who did not need to become data engineers.
- Foundry application development
- Ontology design and refactoring
- Data integration from enterprise and legacy sources
- Transformation pipeline engineering
- Operational workflow and writeback design
- 06Data Platforms & Enterprise IntegrationConnecting systems that were never designed to talk to each other, with contracts, lineage and quality checks that keep the result trustworthy.
- Business problem
- Every system holds part of the picture. Integrations were built point-to-point over years, nobody owns the contracts, and reconciliation happens manually in a spreadsheet at month end.
- What BYAK does
- We define explicit data contracts, build resilient event-driven and batch integrations, and make quality and lineage observable so problems surface as alerts rather than as wrong numbers.
- Business outcome
- Reliable data movement between systems, a single reconciled view of the operations that matter, and integrations that survive their source systems changing.
- Integration architecture and data contract design
- Event streaming and message-based integration
- Change data capture
- ETL and ELT pipeline engineering
- Data modelling for analytics and operations
- 07Cloud & Infrastructure ConsultingInfrastructure designed for the reliability and cost profile the business needs — reproducible, observable and operable by your own team.
- Business problem
- Cloud estates grow by accident. Environments drift, nobody can rebuild production from source, costs rise faster than usage, and reliability depends on the two people who remember how it was set up.
- What BYAK does
- We define reliability targets first, then build reproducible infrastructure from code with the observability and operational practice to meet them — sized to the team that has to run it.
- Business outcome
- Environments that can be rebuilt from a repository, costs that track usage, and an on-call rotation that is survivable.
- Cloud architecture on AWS, Azure and Google Cloud
- Kubernetes platform engineering
- Infrastructure as code
- CI/CD and release engineering
- Observability and SLO design
- 08Software Architecture & Technical StrategyIndependent architectural assessment and technical decision support for leaders who need a defensible answer, not a vendor’s preference.
- Business problem
- Significant technical decisions are made with incomplete information, under time pressure, often on advice from a party with an interest in the outcome. The consequences appear years later.
- What BYAK does
- A structured, independent assessment with the options, trade-offs, costs and risks written down, so the decision can be defended to a board and revisited when circumstances change.
- Business outcome
- A decision your leadership can stand behind, and a plan your engineers can execute.
- Architecture assessment and review
- Technical due diligence
- Build-versus-buy and vendor evaluation
- Modernisation and migration planning
- Delivery process and capability assessment
- 09Technical Due DiligenceAn independent, evidence-based view of a technology estate for investors and acquirers — what it is, what it costs to own, and what could go wrong.
- Business problem
- Technology is a growing share of what gets acquired, and the diligence on it is often a management presentation and a repository tour. The expensive surprises — an unmaintainable core, a licence problem, a security posture that fails the first customer review — appear after completion.
- What BYAK does
- We assess the estate against evidence: code, architecture, infrastructure, delivery data, incident history, security controls and licence inventory, with the people who run it. Findings are rated by their effect on value, integration and risk, and written for two audiences.
- Business outcome
- A defensible view of the technical asset, the cost to own and integrate it, and the conditions worth putting in the agreement.
- Code and architecture assessment
- Infrastructure and operability review
- Security posture assessment
- Open-source licence and supply-chain analysis
- Delivery process and capability assessment
Engagements often combine two or three of these. The services page sets out how each one is scoped, what it delivers and which are commonly run together.
04Specialist capability
Palantir Foundry,delivered to the pointof operational use.

05Security
Security belongsin the architecture,not in the appendix.
A report at the end of a project arrives when the design is fixed and the deadline is not. We do the work earlier, where a finding still costs days instead of quarters.
The most severe application findings are rarely exotic. They are ordinary access-control failures in systems where nobody can answer a simple question: who is allowed to see this record?
Architecture reviews
Trust boundaries, data flows and failure modes assessed against the way the system is actually deployed.
Application security audits
Manual, architecture-aware review of business logic, session handling and workflow abuse cases.
API security
Authorisation on every endpoint, rate and quota design, schema validation and error-surface control.
Authentication & authorisation
Identity architecture, token handling and access-control models that are centralised and testable.
Cloud configuration review
Identity, network exposure, storage policy and drift across accounts and environments.
Threat modelling
Structured sessions producing documented assets, actors, abuse cases and mitigations.
Vulnerability analysis
Reproduced findings rated by exploitability and business impact, never a raw tool export.
Secure development practices
Pipeline hardening, dependency policy, secrets handling and review standards your team can sustain.
Remediation planning
A sequenced plan with owners and effort estimates, followed by verification that the fix holds.
Security consulting and independent assessment are separate engagements — one changes how the system is built, the other tells you where it stands today.
06Delivery
How the workactually runs.
The same seven stages apply whether the engagement is a two-week assessment or a two-year platform build. What changes is the depth of each stage, not whether it happens.
- Increment
- Working software every two weeks
- Visibility
- Scope and spend reviewed each increment
- Exit
- Documented handover at any stage boundary
- 01
Understand
You receive A written problem statement, a constraint register and an agreed definition of what success means in business terms.
- 02
Analyse
You receive An assessment of the current state with the specific risks, dependencies and unknowns that will shape the design.
- 03
Architect
You receive Architecture documentation, decision records, a threat model and a phased delivery plan with a cost envelope.
- 04
Build
You receive Working, deployable software every two weeks, with a demonstration against real scenarios and a current view of scope and spend.
- 05
Validate
You receive Test results, performance characteristics under expected and peak load, and a security assessment with findings resolved or explicitly accepted.
- 06
Deploy
You receive A production system, runbooks, operational dashboards and a support arrangement agreed in advance.
- 07
Improve
You receive A review against the business case, a maintained architecture record, and a plan for the next phase — or a clean handover.
07Positions
Answers otherfirms avoid.
These are asked before most engagements. The honest answer sometimes costs us the work, which is the point of giving it.
- Do we need Kubernetes?
Frequently not. Kubernetes pays off with many services, many teams, or genuinely dynamic scaling requirements. Below that it can add operational cost without adding capability. We will tell you when a managed platform is the better economic answer.
Cloud Architecture- Will you recommend that we hire you for the implementation?
Not by default. Advisory engagements are priced and scoped independently, and the recommendation is written to be executable by your team or another supplier. If we are a good fit for the delivery we will say so, and you should weigh that accordingly.
Technical Strategy- What if Foundry is the wrong tool for our problem?
We will say so. We build data platforms on other technology as well, so our recommendation is not tied to a single platform choice.
Palantir Foundry- Do we need a data warehouse or a lakehouse?
Often the answer is neither, at least not first. Many organisations get more value from fixing the operational integration layer than from adding another analytical store on top of unreliable inputs. We assess before recommending a platform purchase.
Data & Integrations
Have a complexsystem to build?
Let’s turn the technical challenge into a dependable business platform. Tell us what the system has to do, and we will tell you what it takes.
