What I'm looking for

I'm looking to build secure, cloud-native platforms where I can improve CI/CD, observability, reliability, and scalable microservices while mentoring engineers and solving high-impact technical problems.

I've built and scaled mission-critical fintech and telecom platforms that sustain 500,000+ daily transactions at 99.99% uptime.

At GDExperts, I architect and maintain secure, fault-tolerant backend services in .NET Core and Spring Boot. I containerize microservices with Docker, deploy them on Kubernetes, and embed SonarQube security practices into delivery workflows.

I've led DevOps improvements through CI/CD, observability, and automated testing, reducing MTTR by 35%, increasing deployment frequency by 25%, and reducing regression defects by 30%. I use Prometheus, Grafana, xUnit, and PyTest to strengthen reliability and troubleshooting.

Previously at Autonomous Codestore, I built full-stack Django and React applications, MQTT messaging for IoT fleets, and performance-focused database designs. I also mentor junior engineers, establish coding standards, and focus on secure, high-performance delivery.
