What I'm looking for

I’m looking for full-time remote work where I can own full-stack delivery, refactor safely, and optimize performance and infrastructure. I want teams that value code quality, testing, and reliable deployments.

I’m a Senior full-stack web developer with 16 years in web development, specializing in PHP (pure PHP and frameworks including Laravel—7.5 years, Symfony—3 years, CodeIgniter—2 years, Yii—7 years) and modern frontend engineering (Vue.js/Nuxt.js, React/Next, TypeScript, Svelte). I build and refactor production systems with clean standards (PSR-4/PSR-7/PSR-12), and I ensure reliability using PHPUnit feature/unit tests and Jest where needed.

My work consistently blends development with DevOps and performance: I’ve implemented Dockerized delivery and CI/CD on GitLab, added OpenTelemetry, and tuned Redis caching for production stability. I’ve driven measurable outcomes—improving frontend performance from 17% to 80%, optimizing architectures to support 10,000+ simultaneous connections via WebSocket-driven updates, and consolidating services to reduce technical debt and accelerate time-to-market.
