My Expertise

Software Engineer, end-to-end

Deep expertise in infrastructure and backend. I move across the whole stack when the problem calls for it.

/>

Infrastructure & Reliability

Systems that scale without breaking in production: predictable rollouts, observability, and rollback that actually works.

  • Kubernetes / CI-CD
  • AWS / Azure / Terraform
{}

Backend & Data

APIs and pipelines that hold up under real load, focused on performance, cost, and long-term maintainability.

  • Python / Node.js
  • Data Engineering
AI

Applied AI

Agents and RAG that solve a real problem, not a demo: evaluation, cost, and observability from day one.

  • LLMs / RAG
  • Databricks
