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.

Engineers’ machines, stolen GitHub logins, an internal system a migration left open, a system that came with an acquisition, two network changes. None of it was a clever exploit of the product. The same three questions catch all six: what do you run, who can change it, and how fast can you undo a change.
Breach
Way in: engineers’ machines
$6.3bn taken; Binance says $2.85bn was frozen or intercepted
Binance’s November 3 report describes a months-long campaign: a tampered Homebrew installer in June, a fake job interview in September, then an internal AI tool used to take over two more engineers’ devices.
The lessonDeveloper machines and internal tools reach production. Hold installers, take-home tests and AI tools to production rules.
Breach
Way in: a system a migration left open
ID documents passports and driver’s licenses among the records read
A 2025 server migration put an internal, VPN-only system on the internet. Self-registered accounts read archived customer data from June 27 to July 2; DigiCert says certificates were not affected.
The lessonCheck what a migration exposed, not only what it moved. Scan your own perimeter after every change.

Way in: stolen GitHub logins
4,837 accounts hijacked, by Aikido’s count
The accounts pushed a workflow that stole CI secrets, cloud credentials and tokens from build runners. Aikido counts at least 1,806 repositories that ran it.
The lessonCI secrets are production keys. Use short-lived OIDC credentials and review every change to a workflow file.

Way in: a system that came with an acquisition
$5M ransom demanded by a group claiming 100 GB of data
Maersk says the intrusion is isolated to a local system at a company it acquired, with no sensitive data disclosed so far and no disruption to shipping. The data claims are the attackers’ own.
The lessonAn acquisition brings its servers along. Inventory them on day one, then patch, merge or switch them off.

What failed: servers handling secure connections
Outlook & Teams down for organizations worldwide, into the next day
Exchange Online, Teams, SharePoint and Copilot failed from 1:26 PM ET. Microsoft said a process that sets up secure connections was overwhelmed and rolled back a recent network change; it found no sign of an attack, and its review is pending.
The lessonMost outages start with a change. Roll changes out in stages and keep the rollback one command away.

What failed: air traffic control telecoms
4,000+ US flights cancelled, by FlightAware’s count
Every US departure was held from 3:54 to 8:15 PM ET. Officials blamed overloaded routers in an old system after an update; Homeland Security says there was no cyberattack and no link to Microsoft’s outage.
The lessonOld systems fail on the day you change them. Know which ones you depend on, and rehearse running without them.

An access review maps every path from a person’s machine to production, the cloud and payments. An infrastructure audit finds the legacy systems, risky changes and single points of failure that turn into outages.

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.
Cloud infrastructure & DevOps →
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 →
Documents, email, reporting and data entry handled by software wired into your CRM, ERP and spreadsheets, on APIs that are documented, versioned and tested.
Business automation services →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.
