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. A distributed senior team, working worldwide.

None of them needed a clever exploit of anyone’s code. A stolen app secret, hijacked developer tokens, a runtime nobody had patched, one engineer’s laptop. This is the chain we close for clients.
Way in: a stolen app credential
162 Microsoft 365 tenants breached, by Huntress’s count
A credential belonging to the backup app was used to sign in to its customers’ tenants. ConnectWise suspended the service; Microsoft calls it a supply chain attack.
The lessonEvery third-party app in your tenant holds a key. Know which ones exist and what each may do.

1 h 44 min a poisoned release sat on PyPI
Attackers used three engineers’ accounts, reportedly with stolen GitHub CLI tokens, to publish a release that stole cloud and AI credentials from every machine that installed it.
The lessonA token on a developer’s laptop can ship code to thousands of companies. Keep tokens short-lived and scoped.

Every secret customers were asked to rotate
An intruder may have read customers’ encrypted environment variables and decrypted some of them. Railway asked customers to rotate API keys and registry credentials immediately.
The lessonSecrets kept on a platform are as safe as the platform. Know where yours live and how fast you can rotate them.

1 request to take over a PHP site, no login
Two flaws in PHP itself, CVE-2026-109618 and CVE-2026-109619, let an attacker run commands before the application starts. Exploited from day one, on CISA’s exploited list since October 26.
The lessonThe easiest way in is a runtime nobody updated. Patch in days, not quarters.
Our response, and a WordPress check →Way in: not disclosed yet
11.7M account records accessed
Mostly email addresses and login data; Capcom detected it on October 19 and says no card data or customer-set passwords were affected. It warned users to expect phishing.
The lessonA list of emails is a phishing list. The next attack arrives in your customers’ inbox, under your name.

$6.3bn the largest crypto theft on record
Binance says a compromised DevOps engineer’s laptop gave the attacker a service container that could submit withdrawals. It found no sign that a private key leaked.
The lessonA safe key is not enough when anything that reaches the signer can spend. Limits belong in the system itself.

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 when traffic grows and the app groans, we find the actual bottleneck and fix it.
DevOps & Cloud services →
iOS and Android from one React Native codebase — we've taken apps through both stores plenty of times.
Mobile App Development →
Audits, access reviews, emergency response, patching and hardening from the people who run production. Findings in writing, fixed by the same team.
Security services →
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 →
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 →
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.
Need a team next week? Our engineers plug in part-time or full-time — and start immediately.
No discovery workshops, no proposal theatre. Three steps from your first message to a team at work:
Three fields on the contact page. The person who answers the same business day is the one who would do the work.
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.
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.
Big rebuild or tiny fix, bring it. A senior engineer reads your message the same business day and comes back with questions or a fixed quote. No sales sequence, no pitch deck.
