Senior software engineer building AWS backend APIs and AI-powered RAG workflows for fintech and enterprise teams.

What I'm looking for

I’m looking to build customer-facing cloud-native backend services and AI-assisted workflows—partnering with product and business stakeholders to ship reliable features, improve observability and production support, and scale distributed systems.

I build cloud-native backend APIs and customer-facing features, including AI-powered RAG workflows, across enterprise and fintech products at NFQ and Amazon Robotics.

At NFQ, I led development of AI-powered product features using OpenAI, LangChain, TypeScript, and Python, and I built retrieval-augmented generation services using vector search and OpenSearch. I also partnered with product and business stakeholders to turn requirements into production-ready solutions.

Before that, I developed distributed backend systems at Amazon Robotics with Kafka, SQS, and Redis Streams, improving reliability through CloudWatch monitoring and automated alerting, and I supported robotics operations with scalable Python/FastAPI services. Earlier, I delivered fintech backend platforms at Financeit and enterprise financial applications at Sun Life Financial using Node.js/TypeScript and Java/Spring Boot on AWS.
