UpFlyDev — Software Engineers Who Ship
Off the record
We'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. A distributed senior team, working worldwide.

What We Offer
Software development services across the whole lifecycle — from the first prototype to production at scale:
Full Cycle Development
We handle every aspect of your project, from idea to launch. We can also take over existing projects.
MVP Development for startups →
Prototyping & Design
Clickable prototypes in days, clean production UI after — you see the product before you pay for the full build.
MVP Development →
Backend & Frontend Development
Backends that stay up under load, and interfaces nobody needs a manual for.
Web Development services →
DevOps, Scale & Maintenance
We keep production boring: monitoring, CI/CD, backups — and when traffic grows and the app groans, we find the actual bottleneck and fix it.
DevOps & Cloud services →
Mobile Development
iOS and Android from one React Native codebase — we've taken apps through both stores plenty of times.
Mobile App Development →
Security & Hardening
Audits, emergency response, patching and hardening from the people who run production. Findings in writing, fixed by the same team.
Security services →
HTML5 & Web Games
Browser games, playables, and HTML5 ports that load fast on cheap phones, then ship to the stores from the same build. Our own games are live on this site.
HTML5 & Web Games studio →
Consulting
Straight answers on architecture, AI, and build-vs-buy — from engineers who have paid for the wrong decisions, so you don't have to.
Consulting & Architecture Reviews →
API Development
APIs your partners can build on: documented, versioned, and tested against real-world abuse.
APIs & Integrations →Why Work with Us?
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.

How a project starts
No discovery workshops, no proposal theatre. Three steps from your first message to a team at work:
STEP 1
You write, an engineer replies
Three fields on the contact page. The person who answers the same business day is the one who would do the work.
STEP 2
A free scoping call
Thirty minutes on your goals and constraints. We tell you what to build first and what to postpone, because cutting scope is cheaper than cutting corners.
STEP 3
A fixed price, then weekly demos
A written plan with a price that does not move. From the first week you see working software, not status reports, and you own the code from day one.
