Production engineering
meets AI adoption

Most companies aren't stuck on the models — they're stuck on the engineering.
I bring 9 years of production systems discipline to AI adoption, so POCs don't stay POCs.

01
AI-Powered Proof of Concepts
Build fast · Learn fast · Fail cheap

Have an AI idea but don't know if it's worth investing in? I'll help you build a working POC in weeks — not quarters. Validate the value, expose the risks, and make an informed go/no-go decision before committing a full engineering team.

  • Rapid prototype in 2–4 weeks
  • LLM integration into existing backend systems
  • Clear evaluation criteria & outcome report
  • Handover-ready codebase if you proceed
02
AI in the Dev Cycle
Accelerate your engineering team

Help your engineering team adopt AI tooling without disrupting existing workflows. From AI-assisted code review and test generation to intelligent documentation and CI pipeline agents.

  • AI code review agents in CI/CD pipelines
  • Automated test generation for Spring services
  • Developer productivity tooling & assistants
  • Team enablement & adoption coaching
03
AI System Integration
Connect AI to your existing systems

Already have backend APIs, databases, and services? I'll connect LLM capabilities to what you've already built — building the bridge between AI models and your production infrastructure, cleanly and reliably.

  • LLM API integration into Spring backends
  • RAG pipelines over your existing data
  • Agent tooling connected to your APIs
  • Secure, observable AI service architecture

The AI learning
journey

I'm deliberately learning AI engineering at the pace of someone who builds things, not just reads about them. Every topic I study gets turned into something — a mini project, a demo, a published finding. Follow the journey as it happens.
