About

Backend depth with a product heartbeat

I am a Software Engineer with 2+ years of experience building backend systems with Python, FastAPI, Kafka, AWS, Redis, and Elasticsearch. My favorite work sits where architecture meets measurable impact.

Performance First

I like the part where a slow endpoint becomes a quiet non-event. Profiling, caching, query shape, and async work all count.

Distributed Systems

Kafka pipelines, idempotent workers, search-backed analytics, and failure-aware service boundaries are the kind of puzzles I enjoy.

Production Mindset

Clean APIs, readable code, observability, and deployable systems matter as much as the first working version.

Latency Slayer

Numbers that survived production

Recruiters see impact. Engineers see the shape of the system underneath.
