Mobile and web product team for startups.
We take your product from idea to launch — most MVPs ship in 8–10 weeks. Or plug senior engineers into your team within a week. A small senior team from Ukraine, working in the Central European time zone.
Founded 2026 in Chernivtsi, Ukraine. E-commerce, real-time and marketplace products in production.
What we do
-
MVP from scratch
Fixed scope, weekly demos, app in both stores in 8–10 weeks. Mobile app, backend, admin panel and store submission — all included, nothing outsourced.
-
Dedicated engineers
Senior Flutter, Node.js or React engineers embedded in your team within a week. Your process, your tools, your repo. Monthly billing, cancel with two weeks’ notice.
-
Take over and scale
Inherited a codebase from a previous vendor? We audit it, stabilize it and keep shipping. Store rejections, payments, subscriptions, performance — we’ve been through all of it.

How we work
-
Discovery call — 30 min.
You tell us what you’re building and for whom. We tell you honestly if we’re a fit.
-
Scope and estimate — 3 days.
Written scope, timeline and fixed price for the MVP (or a rate card for dedicated engineers). No 40-page proposals.
-
Weekly sprints with a demo.
Every Friday you see a working build on your phone, not a status report. You own the repo from day one.
-
Release and support.
We handle App Store and Google Play submission, including the rejections. After launch — a support plan or a handover, your call.
Dmytro Hutsuliak
Founder & Team Lead
Before TechCrew I led a team of three shipping a legal-tech app to both stores — Flutter front end, NestJS backend migrated from Go, WebRTC video calls, Stripe and LiqPay payments, Apple and Google in-app subscriptions, multi-tenant architecture, and a few rounds of store review rejections along the way.
Full-stack by background: Flutter, Node.js/NestJS, React, Go, FastAPI, DevOps. Two years of freelance before that — production frontends in React, Vue and Angular, MongoDB, Supabase, Stripe subscriptions, Twilio and SendGrid, one Kubernetes workload, and some web3. Master’s in Computer Science at Chernivtsi National University.

FAQ
How much does an MVP cost?
Most MVPs we scope land between $8,000 and $35,000, depending on integrations (payments, real-time, AI). You get a fixed price after the 3-day scoping.
What does a dedicated engineer cost?
From $30/hour for a senior engineer, billed monthly. Two weeks’ notice to stop.
Who owns the code?
You do. Repo is created in your GitHub org on day one; we work in it.
How do payments work?
USD or EUR by invoice, wire or Wise. We invoice as a Ukrainian private entrepreneur (FOP); contract is a standard MSA + SOW.
What’s the time-zone overlap?
We’re on Central European time (UTC+2/+3). Full overlap with EU, 4–5 hours with US East Coast, and we shift for a daily call when needed.
What if it’s not working out?
Every sprint ends with a working build. If you’re not happy, you stop after any sprint and keep everything built so far.
