Solutions that work

For over 3 years we've been building backend solutions for small and medium businesses. We've delivered numerous projects — from simple Telegram bots to complex backend applications with REST APIs, payments, and integrations. We maintain our own servers and environments for development, testing, and deployment.

Reliability

We write clean, maintainable code. Critical scenarios are covered with tests, monitoring and alerts are configured.

Own Infrastructure

Our own servers for development and deployment. Docker, CI/CD, monitoring — all included.

Turnkey

We take projects from idea to production. Development, server deployment, support and improvements.

Why work with us

We're a young, energetic team. For over 3 years we've been adopting the freshest approaches to development and actively using AI to raise quality and ship to production faster. Over those years we experimented a lot and rebuilt our processes until we found the balance between speed, quality, and security.

Fast results

We build and improve your product on tight timelines — without sacrificing quality.

Documentation

Every project is fully documented — the code is clear and easy to maintain.

Security audit

Before launch we check the project for vulnerabilities, so you can hand it to users with confidence.

Turnkey

You get a finished solution and never have to babysit the development process.

Small but ours

A team that can deliver any task — on time and done right.

Frequently asked

The things we get asked most often. Can't find your question — drop us a message, we reply within a day.

How much does development cost?

Cost depends on scope and complexity. Starting points: from $500 for a Telegram bot, from $2,000 for a website, from $3,300 for a backend service, from $8,000 for a mobile app. After a short call we provide an accurate estimate — usually within one business day.

How long does a project take?

It depends on the project. A simple Telegram bot with payments — 1–2 weeks. A landing page or corporate site — 1–3 weeks. A full backend with integrations and an admin panel — one month or more. Larger projects are split into stages with intermediate demos.

Do you provide a warranty?

Yes. Defects within the agreed scope are fixed free of charge during a 30-day warranty period after delivery. New features beyond the original scope are scoped and estimated separately.

What's included in post-launch support?

Basic support covers uptime monitoring, dependency updates, and rapid fixes for critical bugs. Pricing is tailored to the project: a fixed monthly retainer for active products, or hourly time-and-materials for steady-state projects.

Do you provide hosting or do we need our own?

Either option works. We operate our own servers in Russia and Europe — we can host the project and run operations end-to-end. If you already have a host, VPS or cloud (Yandex Cloud, AWS, Selectel, etc.), we deploy there and set up CI/CD, monitoring, and logging.

How does payment work?

We work on a 30–50% upfront, balance-on-delivery model. For legal entities — by contract and invoice; for individuals — bank transfer or electronic receipt. Smaller projects are negotiated individually.
