01 The founder
Principal engineer · Belgrade
Nikola Radošević
Founder, Catapult
Your product is built by a former CTO — not sold by a senior and handed to a junior team.
Fourteen years across two extremes of software: government-grade security systems where mistakes aren't an option, and startup products where speed decides everything. AI agents multiply the output — the judgment, architecture, and accountability stay with one person.

Day 1 → launch
Code lands in your GitHub from day one. Infrastructure and data stay under your ownership. Daily proof of progress — a link, not a status report.
Launch and hand off.
Handoff + warranty
Live URL, tests, setup docs, a recorded walkthrough, and post-launch support with a defect warranty. The clock starts once scope and access are confirmed.
04 The edge
Direct, not bureaucratic. Fast, not rushed.
Senior judgment. AI-native speed.
No project managers, no handoffs, no sales-to-delivery gap. The founder who scopes your product architects and ships it — with an AI-native delivery engine multiplying the output.
Gov-grade engineering habits.
A background in national security systems — ePassports, HSM-backed signatures — shows up in every build: tenant isolation, audit trails, review gates, and tested deploys. Even on a one-week MVP.
You own everything.
Code lands in your GitHub. Infrastructure and data stay in your accounts. Documentation and a recorded walkthrough on handoff — no lock-in, no dependency on Catapult to keep running.
05 The terms
Fixed price. Fixed timeline. No surprises.
Every engagement is a fixed quote, scoped to your product — from one-week MVPs to multi-week builds, plus audits and fractional-CTO work. Once scope is signed off the number is final: if the estimate runs over, Catapult absorbs the overrun. Full source in your GitHub, deployment, docs, and a recorded handoff are always included.

Yes — for a scoped MVP: a defined user type and the critical workflows around it, live in production at the end of the week. Complex products with multiple roles and deep integrations run 2–4 weeks. The free 60-second estimator tells you upfront which one your idea is. No surprises after we start.
07 The launch window is open
Your product, live this week.
No sales handoff — Nikola personally reviews every request and tells you whether it fits a one-week MVP or a bigger build. Fixed price, full source in your GitHub.
