Software Engineer @ Thoughtworks

About

I'm a Software Engineer with 3+ years of experience building production-scale platforms across FinTech and enterprise applications, taking full ownership from system design through deployment. At Thoughtworks, I currently lead development of an AI-powered customer support platform that has cut operational costs by 40% and automated 65% of support tickets. I architect RAG-based pipelines using LangChain, OpenAI API, and Pinecone, and manage cloud-native infrastructure on AWS with Docker and Kubernetes, maintaining 99.9% uptime across systems handling 10M+ monthly transactions. Before that, at Newgen Software Technologies, I engineered a biometric authentication system for IndusInd Bank serving 2M+ users, delivered full-stack banking apps for Axis Bank, and led AWS cloud migrations that reduced deployment overhead by 30%. My core stack: Python · TypeScript · React.js · Next.js · FastAPI · Node.js · AWS · Docker · Kubernetes · LangChain · Pinecone · PostgreSQL · Redis What I bring to a team: I take end-to-end ownership and work closely with product, design, and business stakeholders, not just within engineering. I'm obsessed with performance, having cut API latency by 45%, reduced release cycles by 60%, and improved system throughput at scale. I also build real AI systems including RAG pipelines, vector search, and prompt engineering that solve actual customer problems. I'm currently pursuing my Master's in Information Technology at Arizona State University, graduating May 2026, and actively seeking full-time Software Engineering roles in the US. Open to Full-Stack, Backend, AI/ML Engineering, and Platform Engineering roles.
