The trust anchor

The person who scopes it ships it.

Nikola Radošević

Founder & principal engineer, Catapult

Full background on LinkedIn

Fourteen years across software's two extremes: government systems where mistakes are unacceptable, and startup products where waiting is the mistake. AI agents multiply output; architecture, review, and accountability remain human.

Selected work · 07 builds

Products with a pulse.

Not concept art. Working platforms, native apps, agent infrastructure, and the tools Catapult uses to run itself. Open any project for the full case study.

How it works

Three moves. One owner.

The process is intentionally small. Every layer removed is time returned to the product.

01

Define

Scope it in writing.

Send the problem, the users, and the one workflow that must work. The estimator returns feasibility, a stack, and a price band. Nikola turns that into a written scope and fixed quote.

Deliverable · Signed scope + fixed number

02

Build

Watch the product appear.

Code lands in your GitHub from day one. Infrastructure and data remain in your accounts. Progress is a working URL you can click, not a standup or slide deck.

Deliverable · Daily working build

03

Launch

Own the whole thing.

You get the live URL, tests, setup docs, a recorded walkthrough, post-launch support, and a defect warranty. The clock starts once scope and access are confirmed.

Deliverable · Production + handoff

Why Catapult

AI is the leverage. Judgment is the product.

Speed matters only when the thing at the end is sound. Catapult combines an AI agent fleet with one experienced human who is accountable for every decision.

Principle / 01

Direct senior access

The same person sells, scopes, designs, builds, reviews, and ships. There is no sales-to-delivery gap and no junior team hidden behind a senior introduction.

Principle / 02

Security is a habit

A background in ePassports and HSM-backed signatures shows up in tenant isolation, audit trails, review gates, automated tests, and deliberate production deploys.

Principle / 03

Ownership by default

Source in your GitHub. Infrastructure and data in your accounts. Setup docs and a recorded walkthrough. The relationship can end without the product ending.

Pricing · No mystery math

A number you can make a decision on.

The quote is fixed when scope is signed. If the build takes longer, Catapult absorbs the overrun. Every tier includes source in your GitHub, deployment, documentation, and a recorded handoff.
