What I'm looking for

I’m seeking senior backend roles focusing on scalable API design, microservices, and CI/CD automation in teams that value clean code, observability, and continuous delivery.

I am a resourceful senior backend developer with 6+ years building robust APIs and enterprise-grade services using Laravel, Yii, Slim, and Node.js. I prioritize clean code, testability, and Agile best practices to deliver maintainable systems.

I have led modernization efforts that migrated legacy PHP monoliths to modular Laravel architectures and introduced Node.js microservices for real-time processing. My work on CI/CD pipelines, Docker, and AWS ECS reduced deployment errors and downtime significantly.

Technically, I design event-driven, high-availability systems integrating Redis, RabbitMQ, Fastly, and observability tooling like New Relic. I’ve architected multi-tenant API platforms with JWT auth, Swagger documentation, and standardized error handling.

I consistently focus on performance and scalability—optimizing caching, async job processing, and monitoring to improve response times and developer onboarding. I aim to build reusable, secure services that streamline operations and accelerate delivery.
