PHP & Java engineer building reliable back-end systems for clients worldwide. I work with companies in Europe, Asia and North America, delivering software that is maintainable, documented and ready for production.
I am an independent software developer based in Kazakhstan, providing development services to international clients. My focus is server-side engineering: business logic, data models, APIs and integrations that keep products running day after day.
Most of my work is done in PHP and Java. I take responsibility for the entire delivery cycle: I clarify requirements, propose an architecture, write and test the code, deploy it to your servers and stay available for support afterwards.
Communication is in English, in writing and on calls. Every project gets a written scope, transparent estimates and regular progress reports.

Architecture reviews, code audits and technology selection for start-ups and established businesses.
Primary languages are PHP and Java; everything else is the tooling around them.
A simple, predictable process for clients in any country.
We discuss your goals, constraints and timeline; I prepare a written scope and estimate.
A simple contract or written offer fixes the scope, milestones and price.
Iterative delivery with weekly progress updates and access to a staging environment.
Deployment, hand-over of source code and documentation, then support on request.
