Two products I built end to end, both live and used by real people.

Firstline-ai

A cold email tool I designed, built and launched. Upload a prospect list and it researches each company's site and LinkedIn profile, then writes three scored opening lines per prospect and picks the strongest. Bring your own API key from any provider and choose the model you want to use.

  • Reads each prospect's website and LinkedIn before writing a word
  • Three scored openers per person, best one chosen automatically
  • Works with any provider: bring your own API key and pick the model

Bookkeeping for traders

KMB-Talk

A bookkeeping app for traders who buy and sell on credit. It began as a public repository of mine. When I heard a trader was struggling with exactly this problem, I showed it to him. He liked it, so I adapted it to his business, set it up for English and French and added a mobile app. It is now his private product, used every day by him and his employees.

  • Two currencies with a system rate and a market rate kept side by side
  • Warns before a sale goes below cost, and sells supplier stock first
  • Offline queue that syncs on reconnect, plus thermal receipt printing

  1. It started as a public repository of mine.
  2. I heard someone had a problem it could help with, and showed it to him.
  3. He liked it. I adapted it to his business, internationalized it and added a mobile app.
  4. It is now a private product, used by him and his employees.

This link opens the test environment only.
