Senior Software Engineer · Full-Stack Developer · AI Product Builder

What I do

I have 12 years of experience in software development. Over the last 5 years, I have worked with JavaScript, Next.js, React, and Node.js — building web applications and backend APIs. I also work with AWS, Docker, Git, and Jira for infrastructure, development workflows, and delivery planning. Over the last 2 years, my focus has shifted toward AI and AI-assisted software development.

How I build

I follow the AI Development Lifecycle (AIDLC) and have used Kiro, Amazon Q, Claude AI, ChatGPT, and Codex throughout my development cycle — from ideas, requirements, and system design to coding, debugging, code review, testing, and deployment. I direct the AI tools and validate their output, taking ownership of engineering decisions and the final software. Explore my process on the homepage and in each project's case study.

What I'm learning

I am actively learning generative AI, agentic AI, and retrieval-augmented generation (RAG), and the Model Context Protocol (MCP), and applying that learning in my projects. I am also developing my technical leadership skills as I grow toward a leadership role. Follow the work in my case studies.
