I take AI products from idea to paid launch.

I'm Haris Muhibić, an AI product engineer and architect in Sarajevo. I've built and led software for SaaS companies since 2018. Since 2025 I've architected production AI: sales agents, voice and video pipelines, analytics agents and coding agents. I also ship products of my own.

How I build

Deterministic systems with the model at the edges, chosen by measurement. Code does what code can do reliably. The model handles judgment calls. Every model choice comes with an evaluation and a cost per request.

  1. Research that can kill the idea. A dated brief that keeps facts, guesses and gaps apart.
  2. Unit economics before code. Cost per user, cost per request, margin at scale.
  3. A spec and a decision log. So you can see why each choice was made.
  4. Vertical slices, built with coding agents. Tested, one working feature at a time.
  5. You verify every slice. Passing tests alone don't count as done.
  6. Launch with operations in place. Billing, analytics, status page and cost alerts from day one.
