Core Delivery

Custom software development, dedicated teams, and delivery support for systems that must keep moving.

Software Engineering

Ship product work faster while keeping architecture, reliability, and cost defensible.

Platforms and products that must stay fast, safe, and worth running.

  • Faster release path
  • Lower delivery risk
  • Architecture decisions leadership can defend

Security Audit

Reduce incident and procurement risk with evidence across real attack paths.

We audit desktop software, mobile apps, backend services, AI features, APIs, embedded surfaces, and the trust boundaries between them as one real system.

  • Lower incident risk
  • Buyer-ready evidence
  • Clear remediation order

Ransomware Recovery

Restore operations after encryption, protect the clean rebuild, and reduce repeat compromise risk.

We help teams recover after ransomware (crypto lockers / encryptors) with a calm, evidence-led track: stop the spread, validate what is encrypted, attempt safe decryption when…

  • Safer recovery path
  • Reduced downtime pressure
  • Hardening before return to service

Consulting

Make architecture, modernization, migration, and delivery decisions with evidence instead of drift.

Architecture, modernization, research, security, AI, migration, and performance decisions for teams that cannot afford the wrong bet.

  • Defensible architecture decisions
  • Reduced wrong-build risk
  • Sharper priorities before spend

PoC Engineering

Validate the technical bet before scaling into outsourcing, a dedicated team, or a larger build.

We build proof-of-concept systems across AI, software engineering, reverse engineering, embedded work, security research, and difficult integrations when the team needs evidence before committing to a…

  • Protected budget
  • Faster go/no-go
  • Evidence before commitment

AI Systems

AI engineering, security, governance, and production delivery for agentic and data-heavy systems.

Agentic AI Engineering

Move agentic AI into production with useful workflows, guardrails, and supportable operations.

We design and harden agent workflows that call tools, make bounded decisions, and stay usable in production.

  • Faster AI rollout
  • Lower automation risk
  • Observable runtime behavior

AI Security & Governance

Control what AI can access, decide, and execute before it touches sensitive business systems.

We secure LLM features and agent workflows with threat models, authorization, data boundaries, and auditability.

  • Safer AI approvals
  • Cleaner audit trail
  • Reduced data and permission risk

AI Data Leakage Prevention

Keep sensitive data from crossing the wrong AI boundary and slowing enterprise adoption.

We design and audit the data boundaries around AI systems so sensitive information stays out of prompts, retrieval, memory, logs, and model outputs.

  • Reduced leakage risk
  • Safer enterprise rollout
  • Cleaner data boundaries

Inference Optimization

Reduce latency and serving cost without sacrificing product quality.

We optimize serving stacks for AI products where response time and GPU spend are already business problems.

  • Lower infrastructure cost
  • Lower latency
  • Better unit economics

Autonomous AI Systems Deployment

Move complex AI automation into production with approvals, observability, rollback, and cost control.

We take multi-step AI systems from promising prototypes to controlled production workflows with integrations, approvals, observability, rollback, and cost discipline.

  • Controlled rollout
  • Reduced operational surprise
  • Human approval where it matters

Deep Engineering

Low-level engineering, reverse engineering, kernel work, and performance systems for buyers who need depth.

Low-Level Engineering

Solve native performance and OS-boundary problems that affect cost, stability, and roadmap confidence.

Native engineering for runtimes, SDKs, endpoint components, device software, and systems that need real control.

  • Lower latency
  • Cleaner native boundaries
  • Better stability under load

HFT Engineering

Engineer deterministic trading systems where latency variance becomes direct commercial cost.

Trading infrastructure for teams that care about p99.9, replay, recovery, and real market conditions.

  • Lower tail latency
  • More predictable execution
  • Costly variance reduced

Kernel Engineering

Ship deep OS integration without destabilizing the host or creating rollout risk.

We build kernel-mode components for endpoint security, device software, observability, and performance-critical paths.

  • Safer OS integration
  • Reduced rollout risk
  • Stronger endpoint reliability

Reverse Engineering

Recover the truth hidden inside opaque software and firmware so decisions stop depending on guesses.

We reverse engineer firmware, desktop software, embedded components, update packages, and opaque binaries when documentation is missing, trust is uncertain, or behavior has to be proven…

  • Unknowns turned into evidence
  • Faster interoperability decisions
  • Reduced vendor lock-in risk

Clients Across Key Engineering Markets

Spain, Germany, the Netherlands, Italy, Poland, Ukraine, the United States, Singapore, and Japan.

Engineering Breadth

One team for software, AI, and systems that move work forward.

We work across product engineering, neural systems, low-level software, frontier prototypes, and the security and privacy controls serious buyers now expect around AI and critical software.

Software & Platform Engineering

Application and systems development that ships under pressure

This is the delivery core: software engineering, platform work, APIs, distributed systems, performance tuning, and the sort of native depth needed when reliability and speed are part of the product.

Domain Software Delivery product engineering
Domain Distributed Systems platform scale
Domain API & Backend service architecture
Practice Performance Engineering latency and throughput
Stack C++ / Rust native systems
Practice Platform Modernization rewrite or recovery

AI, Neural & Agent Systems

Neural-network and AI engineering beyond demos and wrappers

We build applied AI systems where models, prompts, retrieval, orchestration, inference economics, and runtime control have to work together as one production system.

Domain Neural Inference model execution
Domain RAG Systems retrieval workflows
Domain Agentic Workflows tool orchestration
Practice Prompt & Tool Control runtime discipline
Practice Inference Optimization cost and latency
Practice AI Evaluation quality and drift

Prototypes, Research & Quantum

PoCs for serious product bets, research tracks, and frontier computing

Some work begins before the roadmap is clear. We build technical prototypes, research implementations, and exploratory systems when clients need proof, feasibility, or a sharp read on a hard direction.

Format Technical PoCs fast validation
Format Research Builds applied exploration
Format Prototype Systems product direction
Frontier Quantum Computing algorithmic exploration
Practice Feasibility Studies go / no-go clarity
Practice Experimental Tooling proof before scale

Security, Privacy & AI Trust

Cybersecurity for AI, software, data, and critical systems

Security is still part of the stack: software audits, AI-specific abuse paths, reverse engineering, data-leak prevention, and the trust controls serious buyers expect around modern systems.

Domain Security Audits desktop, mobile, backend
Domain AI Security models and agents
Domain Data Leakage Prevention sensitive boundaries
Practice Reverse Engineering binary and firmware
Standard Privacy & GDPR data discipline
Practice Threat Modeling design-level risk

How Engagement Starts

Start small, then scale into the right engineering model.

We can begin with a review, a focused build, or a dedicated team track once scope and ownership are clear.

Dedicated team or outstaffing need Cybersecurity or compliance pressure Low-level or AI delivery risk
01

Bring the bottleneck

Bring the system that has started hurting delivery, trust, margin, latency, or uptime.

03

Move with a credible next step

Leave with clearer scope, sharper priorities, lower uncertainty, and a next move the business can actually act on.

Privacy-disciplined delivery

Built to move serious systems forward with privacy held close to the work.

When delivery touches customer data, employee data, regulated workflows, or cross-border operations, privacy stays aligned with the engineering path from the start.

Delivery Privacy-disciplined delivery Security and privacy stay in the same lane across the build path, review path, and data path
Frameworks GDPR, UK GDPR, CCPA/CPRA, PIPEDA Handled as real buyer and legal requirements, not afterthoughts
Contracts DPA / SCC-ready Structured for cross-border safeguards when the engagement needs them
