I build web and mobile products end to end - and then keep them running.
Architecture, backend, interface, iOS and Android, deployment and the monitoring that catches problems before your users do. One person across the whole stack, which is why nothing falls into the gap between contractors.
I'm Yevgen Sukharenko - senior full-stack engineer, and off the keyboard a PADI Divemaster who photographs the Red Sea and built a marine-life platform, two mobile apps and an image-recognition service around it.

What I can build for you
Four kinds of work, all of them things I have shipped to production and still maintain. Whether it is a product from nothing or an existing site that has stopped performing, the same person does the architecture and the code.
Web applications and SaaS, end to end
For founders and businesses who need a product built and running, not a prototype.

Mobile apps for iOS and Android
For products that need to be on a phone, in the stores, and reviewed without a fight.

SEO and Core Web Vitals: audit and repair
For sites that already exist, already have traffic, and are losing both to a slow front end.

AI integrations and technical leadership
For teams that need AI to actually ship, or need someone senior owning the architecture.

Work, and what it did
Products I built and own, and client work on platforms you have heard of. Every case study says what the problem was, what I changed and what it measurably did - because a portfolio without numbers is just a list of claims.
A marine-life platform with its own image-recognition service, native iOS and Android apps - App Clip, widgets and share extension included - on self-hosted infrastructure. Designed, built, shipped and operated solo.
Built by
One person, end to end

How working together goes
The same four steps whether it is a two-week audit or a product built from nothing. You always know what happens next and what it costs before it happens.
- 01
A call, and an honest answer
Thirty minutes on what you are building and why. You leave knowing whether this is something I should be doing at all - sometimes the answer is that your existing team can, or that the problem is not the one you thought it was.
- 02
Scope, estimate, and a written plan
What gets built, in what order, and what it costs. Written down before anything is charged, so we are agreeing on the same thing rather than discovering the gap three weeks in.
- 03
Build in short cycles, with something to look at
Working software on a staging URL you can open, updated continuously. No month of silence followed by a reveal - you redirect the work while redirecting is still cheap.
- 04
Launch, then hand over properly
Deployment, monitoring, and documentation. The code and the infrastructure are yours, and I am reachable afterwards - but you are never locked to me by an undocumented system only I understand.
Have a project in mind?
Tell me what you are building and what is in the way. If I am not the right person for it, I will say so and point you at who is.
