I build robust backend systems for e-commerce and healthcare. TDD, static analysis, and CI/CD are my standard, not a bonus — 7+ years with PHP/Symfony.

I'm a web application developer focused on PHP and the Symfony ecosystem. I have experience designing and building complex e-commerce platforms, insurance tracking systems, and advertising servers. I prefer Test-Driven Development — every feature starts with a test.
I believe quality software comes from clean code, automated tests, and continuous integration. That is why I advocate for PHPUnit, PHPStan, and CI/CD pipelines in all my projects.
Test first, code second. Every feature is covered by tests.
PHPStan, CodeSniffer, and code reviews are part of my workflow.
Docker, Kubernetes, CI/CD — automation from development to deployment.

Send your brief and by the next day you have a working demo on a private deploy link (basic auth, visible only to you). Ideal for quickly validating an idea or pitching to investors before full development.
Custom presentation websites and landing pages — from a simple business card to multilingual corporate sites with SEO, contact forms, and structured data. Focus on load speed, accessibility (a11y), responsive design, and clean code without framework overhead. This site itself is a live example.
Design and implementation of server-side logic in PHP (Symfony, Laravel). REST APIs, third-party integrations, database query performance tuning, and domain logic design with testability in mind.
Custom B2B and B2C e-commerce platforms. Comprehensive solutions from product catalog through cart and payment gateways to ERP and invoicing integrations. Experience migrating legacy solutions to modern Symfony.
Migration of legacy PHP applications to modern frameworks (Symfony, Laravel). Introducing automated tests (PHPUnit, Codeception), static analysis (PHPStan), code review processes, and CI/CD pipelines without production downtime.
Application containerization (Docker), orchestration (Docker Swarm, Kubernetes), CI/CD pipeline setup, monitoring via Grafana/Prometheus, and alerting. Experience migrating from load-balanced setups to Swarm with a 120 req/s peak.

Migrating a B2B/B2C e-commerce platform from LB setup to a containerized cluster
Challenge
Original setup: two application servers behind a load balancer, deploy via rsync, no environment reproducibility. During peaks the system choked and rollbacks were painful.
Solution
Containerization of the application (PHP/Symfony), move to a Docker Swarm cluster with rolling updates. Introduced Grafana + Prometheus for metrics and alerting. CI/CD pipeline with automatic deploys on merge to main.
Result
Stable response time of 1–1.5 s even at a 120 req/s peak. Rolling deploys via Docker Swarm, rollbacks within seconds. Full metrics and alerting cut MTTR on incidents by more than half.
