What I'm looking for

I’m looking for a senior role where I can build AI-enabled business applications end-to-end—strong backend architecture, secure APIs, and performance-focused deployments—while improving operational efficiency, reliability, and developer velocity.

I’m a Senior Software Engineer with 6+ years designing, developing, and deploying scalable full-stack applications with strong backend architecture and AI integration experience.

At Ecolab, I architected and delivered AI-enabled business applications using React, Next.js, TypeScript, FastAPI, Python, PostgreSQL, Redis, and AWS, reducing manual workflow effort by 38% across customer support and internal operations.

I integrate OpenAI API, Claude API, LangChain, LangGraph, and vector search workflows to build intelligent assistants for document Q&A, ticket summarization, knowledge retrieval, and business process automation. I also focus on secure AI workflow layers with JWT/OAuth2, RBAC, API rate limiting, audit logging, and request validation.

Previously at Microsoft, I developed enterprise web applications and AI-assisted automation features, improving document search and internal support workflows by 29%. I’m energized by performance optimization, cloud deployment, application security, and cross-functional product delivery that improves reliability in production.
