What I'm looking for

I'm seeking remote-first roles where I can lead AWS serverless and GenAI integrations, collaborate with product and design teams, scale microservices, and drive automation that reduces costs and speeds time-to-market.

I am a Senior Full-Stack Engineer and AWS Community Builder focused on delivering enterprise-grade SaaS and AI-driven solutions.

With 5+ years of experience, I build production systems using TypeScript/Node.js, React, and Python, integrating LLMs and APIs like OpenAI, Amazon Polly, and Bedrock into scalable microservices on AWS (Lambda, S3, RDS/Aurora).

I design event-driven, serverless architectures that improve throughput and reduce costs, thrive in fast-paced remote-first teams, and hold certifications including AWS Solutions Architect Associate and AWS Security Specialty.
