Qorinx OU is based in Tallinn, Estonia (Sepapaja tn 6, 15551) and works with clients across the EU and beyond. We operate on CET and deliver remotely, so location is never a blocker.
After a scoping call we send one number for the whole build and put the deadline in the contract. No hourly invoices, no surprise overruns, if it takes us longer than planned, that's our cost, not yours.
The senior engineers you meet on the first call. No account managers, no junior benches, no outsourcing chains, which is exactly why we can commit to a fixed price and a real date.
Most projects ship in 2-6 weeks. You get a working version early, then hardening against real data, not one big reveal at the end.
Both. A defined project on a fixed quote, or a monthly stream of tasks handled by the same senior team, with guaranteed SLAs and cancel-anytime. See Services.
Send us the project, a brief, a repo, or just the problem. You get a fixed quote, a timeline and a named senior engineer back, usually within a few days. No sales funnel, no paid discovery phase.
Product design, mobile apps (iOS & Android), backend & SaaS platforms, and AI/ML features, one small senior team covering the full product. See Services.
Yes, stabilising, hardening and modernising systems your business depends on is a core service. See backend rescue.
That's a dedicated service. A senior engineer reviews every line, fixes the dangerous parts, and hands you a plain-English report. See vibe code review & rescue.
Fintech, healthcare and other regulated sectors, yes, with compliance architected in, not bolted on. See Industries.
Yes. Every project build includes 30 days of post-launch support, so anything that breaks in the first month is on us. After that you can extend support or take the codebase in-house, it is documented either way.
Yes. Plenty of clients start with an MVP and keep us on to add features, harden infrastructure and scale for real traffic. You own the code from day one, so you scale with us by choice, not because you are locked in.
Senior engineers write the code, no juniors learning on your budget. Every build ships with tests, documentation and a review pass, so the next developer (or you) can move fast without guessing how it works.
Fixed price, agreed upfront and split into milestones, typically a deposit to start and the balance on delivery. EU invoicing, procurement-ready contracts, no hourly billing and no surprise invoices.
Because pricing is fixed and milestone-based, you always know what you are paying for before work starts. If something is not right, we fix it, the goal is a delivered product you are happy with, not a paid invoice and a walk-away.
You do, 100%, from day one. Full source code and documentation are handed over, with no lock-in to us.
Always, before you share anything sensitive. NDA-friendly, procurement-ready contracts are standard.
Qorinx OÜ is EU-registered in Tallinn, Estonia. GDPR-compliant handling with EU processing options, and your code never trains anyone's model.
EU invoicing and contracts, procurement-ready, with 30-day post-launch support included on project builds.
