What I'm looking for

I am seeking remote contract or full-time roles where I can lead architecture and deliver scalable, secure SaaS or web platform solutions while collaborating in Agile teams.

I am a Senior Full-Stack PHP Developer with over 10 years of experience building, scaling, and maintaining high-traffic web applications and SaaS platforms.

I specialize in Laravel, Symfony, and Laminas, and I have led migrations from monolithic systems to microservice architectures while integrating multiple payment gateways and improving system stability.

I thrive in remote, Agile/SCRUM environments, collaborating closely with product owners, QA, and distributed teams to deliver secure, maintainable solutions and reduce technical debt.

I champion clean code, clear documentation, and long-term ownership of complex systems, and I am open to remote contract or full-time opportunities where I can contribute architectural leadership and hands-on development.
