What I'm looking for

I'm seeking fully remote roles with European or international product-focused teams, contributing to the long-term scalability and evolution of business-critical applications while expanding into AI-driven features and automation.

I've built and maintained production web applications and APIs at Elastique since 2017, working with an international software development team from the Netherlands and remotely.

I design backend architecture, develop features and APIs, model databases, and deliver system integrations using PHP, Symfony, Laravel, MySQL, JavaScript, and Docker.

My work includes performance optimization, debugging complex production issues, and improving the stability, maintainability, and reliability of business-critical systems.

Before Elastique, I delivered end-to-end websites and custom web applications as a freelance developer, handling requirements, design, deployment, and client support. I'm also exploring AI-assisted workflows, automation tools, and LLM API integrations for more intelligent web applications.
