I turn messy workflows into software that just works.

Backend developer turned full-stack, now building with AI. I help businesses replace spreadsheets, copy-paste and disconnected tools with reliable systems — and I stand behind every line that ships.

What I can do for you

  • spreadsheets → apps

    Turn Excel workflows into real software

    I dig out the logic hiding in your workbooks and rebuild it as a web app your whole team can use.

  • integrations

    Payments and data that stay in sync

    Banking, payment and booking systems connected safely — the parts that must never quietly break.

  • automation

    Hours of busywork, handled

    Automated workflows that move information between your tools, so nobody copies and pastes.

  • ai-assisted delivery

    Faster builds, same accountability

    AI speeds up the build. I write the rules it follows and personally review what goes live.

Framer Quoting System

[SCREENSHOT · framer-quoting-system]

A framing shop priced every order across several spreadsheets. I turned those spreadsheets into one simple web app that follows the exact same pricing rules.

How I work, in four steps

  1. Understand the real rules

    I start with how your business actually works — spreadsheets, documents, the steps people follow.

  2. Write them down

    The rules become a clear spec and AI instructions, so nothing is guessed.

  3. Build in small steps

    AI helps draft the code. You see progress early and often.

  4. Check and ship

    I review and test everything myself before it goes live.
