Fourteen years building software that moves the needle. If youre building something that should, .

From the founder

The record runs from founding engineer through Lineups.coms $40M acquisition, to the frontend rebuild behind DailyFaceoffs $23M exit, to work on two more products later acquired by Stanley Black & Deckers Stanley X and by Chowly.

Fortissimo is my studio: a boutique, not an agency. You work directly with me on AI systems, agentic automation, and full-stack products engineered to last.

Between engagements I build my own: Ultimate Fighting Stats and SoundMint.

Fourteen years of software
that moved the needle.

Four exits, two Series A companies, and products serving millions. The record is the work itself.

Client work funds the craft.
Shipping our own keeps it honest.

Some engagements don’t end.
They raise.

The method

Nothing off the rack.

Every build is measured, patterned, and made to the outcome.

  • The probeEvery engagement begins as a conversation that pushes back. I probe until the real business outcome shows itself, and it is often not the thing first asked for. I would rather challenge the brief than build the wrong thing beautifully.
  • The patternI don’t ask for a spec. I write one. The outcome sets the pattern and the pattern sets the build, drawn from where you need to end up rather than from a list of features.
  • The makingSenior hands on every seam, end to end. Working software early and often, fitted against the outcome as it takes shape. Never a head-down build toward a guess.
  • The markThe work isn’t finished when it ships; it’s finished when it hits the mark it was cut for. Fourteen years in, I have never delivered a failed project.
