What I'm looking for

I want to build production-ready backend and full-stack products focused on clean APIs, real-time messaging, and scalable architectures, working in fast-paced cross-functional teams where I can own systems end-to-end.

I’m a Software Engineer with 6+ years of professional experience building scalable backend systems and full-stack web applications. I bring strong expertise in Python, FastAPI, Django, PostgreSQL, MongoDB, DynamoDB, and Redis, and I’ve built real-time systems using WebSocket and MQTT. I’m especially proud of delivering production-ready solutions in fast-paced, cross-functional teams.

In my recent work, I migrated a multi-table DynamoDB architecture to a Single Table Design to improve query performance and reduce read costs, and I built a JEPX price forecasting pipeline integrating a real-time MQTT broker for dynamic arbitrage slot selection. I also design clean, maintainable APIs (FastAPI clean architecture: Domain → Usecase → Infrastructure → Presentation), containerize microservices with Docker, and lead backend development for high-usage systems like a WhatsApp API–integrated CRM.
