Hi, I'm Chams. Founder of Heliocraft.

Lead Tech,
Java & AI
systems.

I lead engineering teams and build the distributed systems underneath serious products: Java, Spring Boot, Kafka, Kubernetes. Ten years in banking, leasing and energy. Now also shipping production AI on that same foundation.

Three ways I can help your team.

Pick the one that matches your problem. Each one leads straight to a short brief.

Lead Tech

Lead your team

I take technical ownership of a product or program: architecture decisions, code reviews, delivery rhythm, and mentoring developers so the team ships with confidence.

  • Technical leadership of squads
  • Architecture and design reviews
  • Standards, CI/CD and quality gates
  • Mentoring developers
Brief me on your team

Development

Build your backend

Hands-on development of distributed systems that hold up in production: event-driven microservices, clean hexagonal architecture, secure APIs.

  • Java 17 to 25, Spring Boot 3
  • Kafka, Avro, Schema Registry
  • Keycloak, OAuth2, OpenID Connect
  • Kubernetes, PostgreSQL
Brief me on your system

AI systems

Ship your AI

Turn AI pilots into governed production systems: model gateways with policy and audit, retrieval over your documents, and agent workflows wired into your stack.

  • Claude API, MCP, agents
  • RAG with Qdrant
  • PII masking, routing, audit
  • Runs on your existing platform
