What I'm looking for

I seek a role building scalable backend and AI-powered systems in a collaborative, engineering-driven company with strong CI/CD, mentorship, and growth opportunities.

I am a full-stack engineer with 10+ years of experience building scalable backend systems, microservices, and AI/ML-powered applications using Python and JavaScript. I design and deploy production-ready SaaS platforms with strong emphasis on reliability, performance, and observability.

My accomplishments include building FastAPI microservices with Celery/Redis handling millions of background jobs, an RAG-based AI assistant that reduced support response time by 40%, and a real-time chatbot scaling to 50K concurrent users with <100ms latency. I also led CI/CD, Kubernetes deployments across AWS/GCP, and established automated testing that reduced release bugs.

I mentor junior engineers, lead Agile ceremonies, and collaborate cross-functionally to deliver measurable product improvements — such as boosting campaign ROI by 15% and improving data reliability by 30%. I seek roles where I can architect scalable systems, integrate AI responsibly, and drive high-impact product outcomes.
