Backend Expert specializing in PHP, Yii2 CRM and API development
An engineering-driven approach
I’m Dmytro, a backend engineer with 8+ years of experience. Over the years, I’ve seen enough projects where template-based solutions collapsed under real production load.
That’s why I work differently: first I analyze the business processes, then I design a backend that can actually handle them.
I build custom backend solutions using PHP / Yii2: CRM integrations, payment systems, external APIs, and working with legacy code — without illusions and without “rewrite from scratch” unless there is a solid technical reason.
My goal is not “to build another website.” My goal is to bring order to the backend, reduce technical debt, and make the system stable and predictable as the product grows.

Technical areas I work with
How the technical workflow looks
I review the codebase, database, and server environment to understand: where the system actually slows down, what is risky for production, and what can be fixed without rewriting everything.
At this stage, I separate real technical necessities from noise and bad decisions.
I propose a concrete backend architecture: data flows, integrations, and scaling points.
This is not a UI mockup — it’s a technical model that shows how the system will work a year from now, not just after release.
I personally implement the backend in PHP (Yii2): business logic, access control, validation, integrations.
The code is built with maintainability in mind — no antipatterns, with logging and a clear structure.
I integrate third-party services (payments, messengers, CRM, APIs) so data is not lost and processes remain stable.
Frontend teams connect to a stable API — regardless of who implements the frontend.
I test the system under load, handle edge cases, and validate error handling.
I optimize queries, caching, and logging — so the system works consistently, not only during demos.
I assist with release, server setup, and monitoring.
I explain how the system works to the client’s team and remain available for support or consultations — without locking anyone in “forever.”
My approach to development
- I personally take responsibility for backend decisions and their stability.
- I work with existing code and legacy systems — without illusions or heroic rewrites.
- I don’t suggest refactoring or rewrites unless there is a real technical need.
- Reliability, predictability, and control come before “fast releases at any cost.”
- I explain technical decisions in plain language — without magic or hidden complexity.
- I can join as a focused backend expert when results matter more than having a “full-time developer.”
For me, code is a business tool.
Not a pretty demo — but stable operation.
The result is a system that doesn’t crash and actually generates revenue.
No commitments. No upfront payment. Just describe the problem — I’ll tell you whether I can help and in what format.
Do you have a technical problem or an idea?
