Release

Layers come together into your finished product

You see every stage, accept the result and get a product ready for your users.

Sound familiar?

The contractor misses deadlines, the budget keeps growing, and big agencies charge you for an entire staff.

You pay for managers and meetings while the release slips by months.

How the team works

One senior engineer. Ten AI agents. One accountable team.

Every agent covers its own area of work, and the senior lead sets the architecture, reviews every result and is personally responsible for the code you receive.

Lead

Senior lead developer

Talks to you directly, designs the architecture, splits the work between agents, reviews every change and owns the release.

10 AI agents by specialisation

  • AnalystRequirements, user stories, estimate.
  • ArchitectData model, modules, API contracts.
  • BackendNestJS, databases, queues, integrations.
  • FrontendNext.js, UI, performance.
  • Mobile & DesktopReact Native, Electron.
  • QAAutomated tests and regression.
  • Code reviewStandards, strict types, no tech debt.
  • SecurityAccess, dependencies, data protection.
  • DevOpsCI/CD, deployment, monitoring.
  • DocsDocumentation and release notes.
1

Quality

Every change passes tests and review by agents, and the final decision is always made by the senior engineer.

2

Speed

Agents work in parallel on different parts of the product, so your release comes sooner.

3

Lowest price

No overhead of a 10-person staff — you pay for the result, not for the headcount.

From idea to release

How development works

Six steps of development — transparent, with fixed milestones and acceptance acts.

  1. Estimate

    Free analysis of your idea, an estimate and a release plan within 24 hours.

  2. Architecture

    Data model, modules, API contracts and the choice of stack.

  3. Development

    Sprints: agents work in parallel, the senior lead reviews every change.

  4. Testing

    Automated tests, regression and code review before every release.

  5. Acceptance

    You accept every milestone with a signed acceptance act.

  6. Support

    Maintenance after launch, updates and SLA on requests.

Separate product

This is our own SaaS product, not a development service. We built it to run our projects and opened it to other studios: projects, tasks, clients, invoices and support in one place. Platform pricing has nothing to do with the cost of custom development.
