I'm a Back-End Developer with 3+ years of experience designing and shipping scalable, production-grade systems in Python, Django, and FastAPI. I care about what happens under the hood — data consistency, performance at scale, async processing, and systems that don't fall over under real financial or user load.
Most of my work lives in:
- 💰 Fintech — ledger-based wallet systems serving 8M+ users and real money movement
- 🤖 AI Platforms — event-driven microservices powering AI content generation at scale
- 🛒 E-Commerce — order processing, payments, and public API design
I like solving the invisible, high-stakes problems: race conditions, distributed consistency, retry-safe async pipelines, and clean domain-driven architecture that scales with the business — not just the code.
Ship it clean. Make it correct. Scale it right.
