I've modernized legacy ERP systems and built production backend platforms with Laravel, PHP, and SQL. At Diagonal Technologies, I migrated a legacy PHP ERP to Laravel, reducing technical debt by 30% and improving maintainability by 40%.
I design RESTful APIs, modular monoliths, and multi-tenant SaaS architectures using domain-driven design and the Service-Repository pattern. My database work includes PostgreSQL, MySQL, and MariaDB schema design and query optimization, delivering up to 33% performance improvement.
Previously at Red Tail Fox, I developed APIs for an event platform serving 1,000+ concurrent users, implemented independently scalable microservices, and established CI/CD pipelines. I've also built real-time chat, event management, learning management, and hotel management systems.
I enjoy solving complex backend problems involving OAuth2, RBAC, queues, WebSockets, Docker, Redis, and secure enterprise data access. My work focuses on maintainable systems that perform reliably as products grow.
