Solid Java systems, and AI agents that actually ship.

As a Lead Tech and architect, I've built distributed platforms for large enterprises for 10 years. Now I plug AI agents into them with the same standards: tests, guardrails, traceability.

Three roles, the same rigour

I can lead your team technically, write the critical parts myself, or design how AI fits into your product. Often all three at once.

Lead Tech

I take technical ownership of a product or programme and help the team become autonomous.

  • Architecture decisions and design reviews
  • Code reviews, standards, CI/CD
  • Delivery rhythm and quality (TDD, BDD)
  • Mentoring developers

Java engineering

I write the hard parts: the ones that must handle load, stay consistent and last.

  • Java 17–25, Spring Boot 3
  • Hexagonal architecture, event-driven microservices
  • Kafka, Avro, Schema Registry
  • Keycloak (OAuth2/OIDC), Kubernetes, PostgreSQL

AI systems

I design agent systems that fit your tools and constraints, not demos.

  • Agents and multi-step orchestration
  • RAG and semantic search (Qdrant)
  • Claude API, local models (Ollama), multi-model routing
  • Guardrails: human approval, tests, audit

Projects

What I build under Heliocraft, outside client work. Each case study covers the problem, the architecture and the results.

Heliocraft Agent OS

An agentic pipeline that turns a spoken request into tested, committed code, with human approval at the sensitive steps.

AI governance platform

Java services that turn Confluence documentation into actionable Jira tickets, and decide which ones an AI can safely take on.
