One person, in writing, from start to finish

I’m Jerry Mazur. I run Tessavio LLC from Manalapan, New Jersey.

I build API integrations, AI automation and custom tools for small businesses: the connections between the programs they already pay for, the follow-up nobody has time for, and small web apps when nothing off the shelf fits.

I designed and built Tessavio Auto, a complete shop management system for independent repair shops that you can click through as a live demo, and the control panel I use for my own DJ live streams. I build with Claude Code every day, including my own automation agents and the MCP server they share.

When you hire me, you deal with the person who writes the code, from the first written plan to the handover.
