New app idea, broken app, or a rejected one?
I build apps from scratch and fix ones breaking in production. More than a decade in iOS - five years building a medtech product in an FDA-regulated industry, and a dozen of my own apps in the App Store. Let me help you with yours.
What clients say
"Vadim was instrumental to the success Epsy enjoyed on iOS, taking it from an idea on a Miro board to the highest rated and most downloaded app of its kind on the store."
James C. · Mobile Engineering Lead, Epsy
"We had a strict deadline, and Vadim managed to complete the job in time. He gave us meaningful feedback and suggested better approaches, not trying to blindly stick to our specification."
Founder · Pre-seed streaming service
"I can say with confidence that it will be difficult to find a better developer. Vadim is achievement-oriented, highly organized, with very good communication skills."
Alex Z. · Co-Founder, eda.so

Questions
Can you build our iOS app end to end?
Yes. That covers architecture, code, App Review, and the App Store release. Epsy, the FDA-regulated epilepsy app I spent five years building at LivaNova, won a CES Innovation Award. If you already have an iOS team, I can join it and build alongside your engineers instead.
Are you an agency, or do we work with you directly?
Directly - you're hiring me, one senior iOS engineer who writes the code, rather than an agency that routes you through a project manager and a team you never meet. For a lot of my clients that's the whole point: one person who owns the work end to end.
How quickly can you start?
A quick call can happen within days. For project work I usually need 1-2 weeks to clear the calendar, though I keep some buffer for urgent firefighting.
Do you work with early-stage startups?
Yes, from pre-seed to Series C and beyond. For very early teams, a short advisory engagement often makes more sense than a full build: you get the architecture guidance without committing to a large piece of work before you've validated the product.
What's included when we work together?
Everything: code, architecture decisions, code review, documentation, async Slack availability during working hours. No surprise add-ons. I bill for time spent working on your project, not for "thinking about it in the shower."
We're in a different timezone. Will that slow things down?
I'm currently in Vancouver (PST), with full overlap for North American teams. For UK and Europe, I'm online by their afternoon. For Gulf or APAC, we'd agree on overlap hours and handle the rest async. I've worked with teams from San Francisco to Dubai.
