What I'm looking for

I’m looking for a role where I can build production AI + backend systems—RAG, GPU inference, and event-driven pipelines—on AWS/Kubernetes, partnering with product teams to ship reliably and improve throughput and latency.

I build backend systems and AI pipelines at startups. 2 years across two YC companies, currently at RedBlox.io.

At RedBlox I shipped production RAG pipelines using LangChain and FastAPI, deployed a SaaS platform on AWS EKS with Helm CI/CD and autoscaling, and built serverless workflows on Lambda processing thousands of images daily. At Optifye (YC W25) I was the first infra engineer — built GPU inference pipeline improving throughput by 70%, set up multi-cluster EKS with Kafka streaming and CI/CD, and created a serverless OCR pipeline that improved processing efficiency by 40%. At ClickPe (YC W23) I built payment backends with Temporal in Python and Go, designed REST APIs with payment gateway integrations, and implemented queue architecture with SQS increasing throughput by 50%.

Led infra setup at Optifye as first engineer on the team. Mentored junior developers on serverless and LLM patterns at ClickPe. Built an LLM code generator that cut service bootstrap time by 50%.

Stack: Python, Go, TypeScript, FastAPI, LangChain, Kafka, Kubernetes, Terraform, AWS, Docker, LiveKit, WebRTC.

Based in India, flexible timezone overlap for US and EU teams. Comfortable with async communication.
