I’m a Senior Backend & Full-Stack Engineer with 5 years shipping and scaling production systems for startups. I own backends end to end—Python/Django and Go services—while staying hands-on across reliability, performance, and delivery.

I’ve driven major runtime wins: I served 500M+ monthly API requests and cut p95 latency from 900ms to 220ms using query optimization, multi-layer caching, and connection pooling. I also re-architected my real-time WebSocket stack (Django Channels with Daphne) to handle 30K concurrent connections, reducing response time from ~5,000ms to ~100ms.

I’m equally focused on pragmatic infrastructure and cost control. I replaced managed load balancing and autoscaling with a custom Caddy-based stack to cut monthly DevOps spend, remove vendor lock-in, and keep zero-downtime deploys—while maintaining observability and fault tolerance through Celery pipelines and retry/dead-letter strategies.

On the AI side, I build LLM and multi-agent systems end to end: RAG (Pinecone/pgvector), agent orchestration, and fine-tuned SLMs with self-hosted image/video generation models (Qwen, LTX) on GPU infrastructure to avoid recurring third-party API costs. I operate as an early engineer with on-call and incident response, mentor juniors, and ship with tools like Claude Code, Codex, and Cursor.
