Hey, I'm Konstantin
Top 3% developer globally. 20M+ downloads delivered.
From Unity Technologies to your startup.
The Real Story
I've been coding professionally for over 11 years. Started on Upwork in 2012 and quickly became a Top Rated developer. Not through tricks or gaming the system - just by delivering quality that speaks for itself.
100% positive reviews over 11 years. That's not luck. That's consistency.
I've worked with everyone from solo founders to Unity Technologies. Built apps that got 12 million downloads. Pioneered AR features before Apple even released ARKit. Fixed performance problems that stumped executives from Google and Microsoft.
In 2023, I joined COSMIC TAPS as Senior iOS Engineer. Now managing a portfolio of apps with 1M+ downloads per year at 99%+ bug-free rate. But I missed the startup energy.
So I launched MVPFast. To bring enterprise-level quality to startups who can't afford to fail.
Your MVP isn't just another project for me. It's your shot at building something real. And with 30+ successful projects behind me, I know exactly how to make it happen.
"I have many years of software development and management experience at highly selective companies like Microsoft and Google, and I found Konstantin's work to be on par with that of those developers."
