Let’s Talk
Big rebuild or tiny fix, bring it. Startups, corporations — every project gets the same senior team. Tell us what you need and we'll tell you straight how to get there.
UpFlyDev — Software Engineers Who ShipWe're UpFlyDev. We've been building software for twenty-something years now, for huge household names and for tiny two-person startups. Honestly? It's gotten pretty hard to surprise us.
New product? Old codebase nobody wants to touch? An AI idea you can't quite pin down? Bring it over. We'll find the smartest way to get it done, no drama, no wasted budget.
We move fast, keep things simple, and build stuff that just works.
We've built web and mobile products for well over a decade, for two-person startups and global corporations. Every layer of the stack, every stage of the lifecycle. This is what we do all day, every day — and it shows. Based in Warsaw, working worldwide.

After this many years in the trade, there isn't much of the stack we haven't shipped: frontend, backend, mobile, cloud. High-load systems, legacy rescues, greenfield builds. Pick a technology below. Odds are we've taken it to production more than once:
Software development services across the whole lifecycle — from the first prototype to production at scale:
We handle every aspect of your project, from idea to launch. We can also take over existing projects.
MVP Development for startups →
Clickable prototypes in days, clean production UI after — you see the product before you pay for the full build.
MVP Development →
Backends that stay up under load, and interfaces nobody needs a manual for.
Web Development services →
We keep production boring: monitoring, CI/CD, backups — and someone who answers when it matters.
DevOps & Cloud services →
iOS and Android from one React Native codebase — we've taken apps through both stores plenty of times.
Mobile App Development →
Architecture advice from people who've paid for the wrong decisions — so you don't have to.
Architecture Reviews →
When traffic grows and the app groans, we find the actual bottleneck and fix it — measured, not guessed.
Performance & Scaling →
Straight answers on architecture, AI, and build-vs-buy — from engineers, not salespeople.
Consulting & Audits →
APIs your partners can build on: documented, versioned, and tested against real-world abuse.
APIs & Integrations →Skip the sales pitch — here's what actually working with us looks like:
We put AI into products and operations where it actually pays — it's daily work for us, not a lab experiment.
From first sketch to a product holding real traffic — we've scaled systems for brands you'd recognize.
Fintech, e-commerce, automotive, media — after this many years, your domain probably isn't new to us.
Two-person startups and household-name corporations get the same deal: straight talk and working software.
