Software Engineer building distributed systems & AI-native infrastructure
I design systems that scale under load and stay correct under concurrency.
🧠 What I Build
I design and ship production-grade backend systems focused on:
- High-concurrency distributed architectures
- Idempotent APIs & transactional guarantees
- Event-driven AWS infrastructure
- Database performance at scale
- AI-native pipelines (LLM + RAG + document intelligence)
I care deeply about correctness, scalability, and business impact.
