About
“I am a Senior Python Backend Engineer with 5+ years of experience building production APIs, asynchronous systems, and automation-heavy backend platforms.”
I have deep experience delivering FastAPI-based services with Celery + Redis background execution for high-volume automation, workflow orchestration, and data processing workloads. I take strong end-to-end ownership across API design, background workers, and production hardening, including timeouts, retries with backoff, idempotency, failure isolation, and run visibility.
I am hands-on with containerized deployments using Docker and cloud infrastructure on AWS. I am experienced in building GenAI-enabled backend systems including RAG pipelines, vector search, tool-calling agents, and controlled agentic workflows for business operations and compliance use cases. I have also built the backend for 6 SaaS products and delivered 50+ projects across startups and enterprises.
