What I'm looking for

I’m looking for a role building cloud-native full-stack products—scalable backend APIs, responsive React experiences, and reliable Azure infrastructure—where I can improve performance, automate deployments, and ship measurable customer impact.

I’m an engineering professional focused on full-stack cloud applications, scalable backend services, and modern frontend development. I’m hands-on with Java (Spring Boot), React, REST APIs, and Microsoft Azure to deliver measurable gains in performance, efficiency, and delivery quality.

In my Azure work, I designed and implemented scalable backend APIs that improved system reliability by 20% under high-load conditions. I also built dynamic, responsive React front-end components that delivered a 30% improvement in UI responsiveness across devices.

I containerized services with Docker and deployed on Azure Container Apps, reducing infrastructure costs by 25% through cloud scalability optimization. I configured Azure Monitor for real-time insights, reducing downtime by 15%, and automated secure deployments with Azure Key Vault and Azure Developer CLI (azd), cutting deployment lead times by 50%.

I’ve also led enterprise-grade microservices and platform automation—integrating Java services with PostgreSQL Flexible Server for a 30% query performance improvement, provisioning production-ready infrastructure with Bicep, and reducing manual configuration errors by 50%. Across projects, I collaborate cross-functionally to ensure reliability, maintainability, and customer satisfaction.
