What I'm looking for

I seek remote roles building scalable web platforms, CRMs or microservices where I can apply SOLID design, testing and DevOps to deliver reliable, maintainable systems.

I am a senior full-stack web developer with extensive experience across PHP (Laravel, Symfony, Yii2), Node.js (Express, Nest), frontend frameworks (React, Angular, AngularJS) and modern DevOps tooling. I build and maintain CRMs, microservices, RESTful APIs and complex integrations for telecom, trading and ecommerce clients.

Over a 12+ year career I have delivered production systems with automated testing, CI/CD, Docker, AWS, and message/broker solutions, and I frequently work fully remote as a freelancer or senior engineer. I emphasize SOLID design, design patterns, DDD and pragmatic OOP to create maintainable, testable software.

My portfolio includes collaborations with EasyMarkets and ItaliaOnline and multiple end-to-end projects (website + CRM) implemented with Node.js, React, MongoDB and PostgreSQL; I aim to solve hard engineering problems and drive reliable, production-grade solutions.
