Tech Lead

About

I'm a Tech Lead with more than five years of experience building products end to end. Most of my work has been across TypeScript, Node.js, React, Java, SQL, and microservices.

What I enjoy most is taking messy or ambiguous ideas and turning them into software that works well in production. Lately I've been building small AI products from scratch, shipping them quickly, and learning from real users as I go. At work, we've also started incorporating AI engineering into development workflows and related areas to improve how we explore, build, and deliver software.

Personal Projects

These are two products I've been building in 2026. Both started as rough ideas and helped me sharpen how I build, ship, and refine products end to end.

Tool for turning LinkedIn posts into branded visuals

Built and launched a product that turns written LinkedIn posts into polished branded visuals in under a minute.
Designed and shipped the full stack myself using TypeScript, React, and Node.js.
Built with Codex, Claude Code, and Cursor as part of the development workflow, taking advantage of newer capabilities such as skills and MCP integrations to move faster during prototyping and implementation.
Added templates, styling controls, and brand customization so the output feels consistent without a lot of manual design work.

Recipe app for turning rough inputs into shareable recipes

Built and launched a product that turns handwritten recipes, voice notes, and pasted text into clean, shareable recipes.
Focused on making the flow simple so people can go from messy input to a usable result in a few minutes.
Built the product end to end with TypeScript, React, and Node.js.
Used Codex and Claude Code throughout development, including features such as skills and MCPs, to speed up iteration while keeping the product quality bar high.
Started with a loose idea and shaped the product by iterating on the UX and real use cases around preserving and sharing family recipes.
Put it in front of real users and used that feedback to keep improving the experience.
