About me 🧾

I'm a Full-Stack Engineer with 1+ years of experience building scalable backend systems, web applications, and GenAI-powered products using Java, Python, Spring Boot, Node.js, React, MongoDB and PostgreSQL.

Skilled in REST/GraphQL API design, LLM agent orchestration with LangGraph, event-driven architecture, microservices, and cloud-integrated systems on GCP and Vercel. Before software, I spent 8 years leading bank branch operations — that background shows up in how I approach reliability and process.
