01.
For over 11 years, I have been designing and maintaining PHP backends (Symfony, Laravel) in high-availability production environments. I also build frontends in Vue and TypeScript and handle containerization and deployment (Docker, Kubernetes, CI/CD).
I thrive in projects with complex business logic: refactoring long-standing monoliths, upgrading PHP versions, implementing asynchronous queues, and decoupling modular boundaries.
In my daily work, I leverage AI agents and LLMs (Cursor, Antigravity, Claude, Gemini) for AST analysis, test scaffolding, and documentation, maintaining full engineering control over architecture and business logic.

I focus on the areas where businesses lose the most: legacy backends, database bottlenecks, manual data synchronization, and a website that brings in no customers.
Problem
Outdated PHP (5.x/7.x) codebase or a monolith the team is afraid to touch, where any new deployment risks production regressions.
What I do
Safe, incremental refactoring without costly rewrite-from-scratch dead ends. Adding regression tests, eliminating bottlenecks, upgrading to PHP 8.x, and restoring codebase stability.
Problem
Application slowing down during traffic spikes, overloaded databases, and bloated controllers carrying messy business logic.
What I do
Architectural cleanup (Service Layer, ADR, Event-Driven Architecture). Offloading heavy tasks to queues (RabbitMQ), optimizing SQL queries and database indexes for high throughput.
Problem
Employees manually transferring data between ERPs, warehouses, e-commerce, or third-party APIs, causing human errors and delays.
What I do
Building resilient, self-healing API integrations (REST / GraphQL / Webhooks / IoT) with automated retry mechanisms, dead-letter queues, and telemetry.
Problem
A business has no website, or one that nobody finds, that loads slowly on a phone and takes no enquiries or bookings.
What I do
I build the path from a simple business-card site to a full system: a fast site with pricing and contact first, then bookings, a shop and an app, up to a multi-location platform. I show it on fictional businesses; the salon's site is already live.
