I do not pass responsibility between frontend and backend — one person owns the result.
About KVI / Ilya
One owner for the whole product.
I’m Ilya, the full-stack developer behind KVI. You work with me directly: I take responsibility for the result from interface and backend to data, integrations and launch.

One person keeps the context of the whole product, so the client does not have to coordinate frontend, backend and integrations across separate contractors.
About / KVI
Development without choosing between “looks good” and “works well”.
I approach web development as one complete product: interface, backend, APIs, data, integrations, performance and launch. That lets me take a project from the problem to a working result instead of treating it as disconnected pieces.
For a client, that means responsibility does not disappear between frontend and backend. I can follow the data through the system, understand how the parts affect each other and investigate issues across the architecture rather than only on one screen.
I follow the data through interface, API, business logic and database instead of leaving problems between separate teams.
The client does not have to coordinate multiple developers or explain the same task several times.
Project context stays intact from the first idea through production, support and further development.

Behind KVI / Personal
More than development.
What helps me create quality products is not only my love for the work, but also the love I have for the person closest to me.
Kamillochka — you are my greatest support and my anchor. Because of you, I keep growing and building a life in which both of us can be happy.
Behind interfaces, APIs and architecture, there are always people — and they are who the product is ultimately built for.
KVI / SYSTEM
Working principles
Problem first, technology second
The stack is selected for the product, timeline and future development — not for a fashionable label.
The client keeps the source and control
The project stays transparent: code, structure, access and logic should never become a black box.
Performance is part of design
Visual effects only make sense while the interface stays fast and comfortable on real devices.
Complexity explained clearly
A client should not need to understand architecture to know the current stage, result and next action.
Process
A transparent process.
No magic, no chaos.
At every stage you can see what is done and what comes next
01
Discovery
I clarify the goal, audience, business logic and constraints so we define a clear scope without unnecessary work.
02
Architecture
I design the interface structure, data, backend, integrations and technical foundation before active development.
03
Development
I build iteratively: interface, logic, API, responsive states and real user scenarios.
04
QA
I test critical scenarios, responsiveness, errors, performance, interface smoothness and final polish.
05
Launch
I prepare production, connect the domain and infrastructure, then hand the product over for real users.
Have a project?
Start with a short message.
No technical brief required. Describe the problem in your own words and I will review the scope personally.
You describe the task
Plain language is enough; no finished specification required.
I review the project
I look at goals, constraints and the technical side.
I reply personally
No account managers or hand-offs between contractors.
We assess the solution
We align on the approach, scope and timeline expectations.
