I kept finding scheduling rules that were harder to express than they should be. I started building a small library to make that work simpler. It is active, but not published yet.

Technologies: TypeScript, Temporal, fast-check

This is a private product I am building around the day-to-day work of a nutritionist. Right now, I am focused on patient plans. It is still in pre-production.

Technologies: Next.js, Elysia, Prisma, Neon, Better Auth

• I wanted a small, quiet place for my work, books, and other curiosities.
• Static pages keep it quick and let the Library remain readable without JavaScript.

Technologies: Octane, Effect, Vite

• I worked on interfaces for identity-provider operations, with complex workflows that had to stay clear and dependable.
• I shaped those workflows with the product and engineering team.
• I cannot share the client name or product details.

Technologies: TanStack, Tailwind CSS, WorkOS

• I turn the design team's work into code for pages that rarely share the same shape.
• Much of my work is in the details — layout, motion, content flexibility, and speed.

Technologies: Next.js, Payload CMS, Tailwind CSS, Motion

• I joined this project knowing almost nothing about intellectual property.
• The interfaces changed as the team and I learned how the domain worked.
• I cannot share the client name or product details.

Technologies: Next.js, Ant Design, Tailwind CSS

I work on client products and the Pixelmatters website, usually close to designers.
