Do you work with startups or enterprises?

Both. What matters is that the product is important enough to need a visible, accountable delivery process — whether it’s an MVP or a system replacing a legacy platform.

Can you work with our in-house team?

Yes. We often work alongside internal engineers, in your repositories and processes, and can take on specific areas like cloud, AI or mobile.

Our engineering team is in Ukraine and works with clients across Europe and beyond, with overlapping working hours for European time zones. See Outsourcing to Ukraine in 2026.

Service · Custom software

Custom software, without the outsourcing black box.

You shouldn’t need to trust a status report to know how your project is going. Nythrex designs, builds and operates production software end-to-end, while scope, progress, budget, risks and technical decisions stay visible to you — and the code, cloud and data belong to you from day one.

What we build

Web platforms & SaaS

Customer-facing products, portals and marketplaces with React / Next.js and robust backends.

iOS and Android with React Native, sharing logic with your web product where it makes sense.

Internal tools

Back-office systems, admin panels and workflow tools that replace spreadsheets and email chains.

APIs & integrations

Cloud platforms

Infrastructure as code, CI/CD, observability and cost control in your cloud.

RAG, agents and document AI built into the product, not bolted on.
