About

Backend engineer with 7+ years of experience building scalable fintech platforms, distributed systems, and AI-powered applications. My background spans high-throughput transaction systems, microservices, event-driven architectures, and modern backend development with Python, FastAPI, TypeScript, Node.js, and NestJS. Recently focused on AI infrastructure — building production services with LangGraph, RAG, and LLM integrations. I enjoy solving complex engineering problems, designing reliable systems, and turning ideas into production-ready software that scales.
