What I'm looking for

I seek senior engineering or tech‑lead roles where I can own architecture, lead cross‑functional teams, and build AI‑enabled, scalable systems with strong DevOps and observability practices.

I am a senior full‑stack developer and tech lead with extensive experience designing and delivering scalable, high‑performance web and mobile systems across cloud environments. I apply SOLID principles, DDD and microservices architecture to ensure maintainability and reliability.

I have led cross‑functional teams and CI/CD initiatives in government and enterprise projects, built RAG/LLM integrations, chatbots and vector search solutions, and implemented observability with centralized logging and monitoring. My hands‑on stack spans Java Spring Boot, Node.js/Fastify, TypeScript, React/Next.js, Ionic, Docker, PostgreSQL/MySQL and cloud platforms (AWS/GCP).

I take ownership of product architecture and delivery, focusing on automated pipelines, secure authentication (JWT/OAuth2), and performant data systems to drive measurable business outcomes and successful digital transformations.
