What I'm looking for

I’m looking to build scalable full-stack products and production AI systems—comfortable across the lifecycle, with cloud-native architectures on AWS. I want roles where I can integrate LLMs via Langchain, ship APIs, and improve UX with modern React.

I’m a full stack developer focused on building scalable web and backend systems with modern JavaScript and TypeScript ecosystems. I bring strong frontend experience with React-based frameworks, plus backend API development with Node.js and Python.

In my current role, I integrate LLMs and generative AI using Langchain and AWS Bedrock, and I design serverless applications with AWS Lambda. I also develop scalable APIs and AI-driven services end-to-end.

Previously, I built and maintained internal web applications and corporate SPAs, combining RESTful API development with TypeORM and PostgreSQL and UX-focused improvements. I’ve also worked on enterprise internal systems and collaborated with cross-functional teams to keep products running smoothly.

My development philosophy is proactive and adaptable across the entire software development lifecycle. I’m comfortable delivering from landing pages and UI work to cloud-native architectures and production-ready AI solutions.
