Ugur Kellecioglu

Founder and product engineer

  1. 01

    Partners, not vendors

    Measured in years, not deliverables.

  2. 02

    AI-native, engineer-led

    AI drafts the code. Engineers decide what ships.

  3. 03

    Field experience

    Shipping products since before the models arrived.

Approach

AI is the future. In the right hands.

AI-written code is fast to produce and expensive to own. We have shipped production software for five-plus years, so we know which parts deserve suspicion.

Not slower than an AI-first shop. Still accountable at 3 a.m.

Partnership

Built to outlast the first launch.

  1. 01

    Discover

    We map the problem, the users and the constraints before anyone writes code. You get a plan and an estimate, not a proposal deck.

  2. 02

    First slice in production

    Something real and deployed early, so we are arguing about a working product instead of a specification.

  3. 03

    Operate

    We stay on: releases, monitoring, the bugs nobody predicted, and the roadmap as it actually changes.

  4. 04

    Compound

    Every cycle leaves the codebase easier to change than we found it. That is what makes year two cheaper than year one.

Pricing

One way to work with us.

AI-accelerated development, billed monthly. We confirm scope, capacity and start date in writing before checkout.

Prices in USD. Starting price; the monthly fee depends on scope and capacity agreed in writing. Service terms

Looking for an engineering partner for the long haul?

A short note about the product, the timeline and who it is for is enough to start. You will hear back from the engineer who would do the work, not a sales team.
