What I'm looking for

I want to keep building AI-powered products—LLM/RAG features, secure APIs, and scalable full-stack apps—then ship them reliably in production with strong performance, security, and maintainability.

I build AI-powered applications, including LLM solutions, RAG systems, AI agents, and automation tools, to improve business workflows at MavenAGI. I integrate LLM APIs with prompt engineering, embeddings, and vector databases into full-stack products, and deploy production apps using AWS and Docker.

Earlier at BentoBox, I built a restaurant management platform with a full admin dashboard using Next.js and Tailwind CSS. I implemented secure authentication and user management with JWT and OAuth, integrated Stripe and PayPal, and improved performance with caching and optimization.

Before that, I worked on healthcare and hospital management platforms as a Web Developer, building responsive interfaces and secure RESTful APIs with React, Node.js, and Express.js. I also designed database structures and state management using PostgreSQL, Redux Toolkit, and Redux Saga, and supported reliable delivery through testing workflows.
