Software engineering company · EU contract · engineers in eleven countries
We build, take over and support business-critical software, and add senior engineers to teams that need them now. Each situation below has a fixed first step and a price.
One reply from Gleb within a business day: questions, a fixed price, or an honest “not worth it”.
Engineering trusted by teams at
Situations
Every card: what is going on, what we do first, what it costs. The details are one click away.
Backend, DevOps, QA automation, full-stack, data and AI, architects. Common stacks: interviews within days, start within a week. Rare stacks: up to two weeks. Vetted by our own engineers before you see them.
For manufacturers, distributors and service companies with an ERP, a lot of Excel and processes that live in people's heads. Two weeks: we map the processes and data, pick the one or two places where AI or automation pays back, and tell you honestly if it doesn't. Then a pilot.
KSeF penalties from January 2027, NIS2 in Poland by April, the Cyber Resilience Act by December, 100-day TLS certificates in March. Your lawyers say what is required. We change the code, infrastructure and processes so it passes.
Or the vendor disappeared, or nobody can explain how it works anymore. We assess it in 10 working days, fix what will break next, and keep it running with a named lead and a response time.
Agencies and freelancers with clients you no longer want to support: talk to Gleb about a clean handover.
Proof, not promises
Three of our projects. More cases and references on each service page or on the call.
The investor-facing frontend had an inherited backlog and broken release cycles. Our senior React/TypeScript engineer joined the team and stayed four years.
Replaced the vendor's legacy document system with a no-code process automation platform: process modelling, dynamic forms, rule-based workflows, audit trail.
Replaced an outdated loan and guarantee management system, including migration of all data from the old system.
Who you will talk to
No account managers in between. The engineers who will do the work join the second call.
