What I'm looking for

I seek senior backend or cloud-native roles where I can lead API and microservices design, mentor engineers, and deliver reliable, test-driven systems while learning cutting-edge AI and cloud technologies.

I am a senior software engineer with ten years of continuous advancement building scalable backend systems, APIs, and cloud-native applications. I focus on delivering quality work on time and within budget while mentoring junior engineers.

My experience spans PHP/Laravel and Node.js back ends, MySQL/Postgres/MongoDB datastores, containerization with Docker and Kubernetes, and AWS/GCP deployments. I lead design of microservices, API integrations, and performance-focused engineering solutions.

I have repeatedly instituted automated testing, documentation, and CI/CD practices that improved reliability and developer productivity, and I regularly collaborate with product and QA teams to ship features quickly and safely.

I am passionate about learning new technologies — including generative AI and LLM tooling — and I bring mentorship, technical leadership, and pragmatic problem solving to teams that value high-quality software delivery.
