Backend engineer at Tezza Business Solutions building secure APIs and release gates for an enterprise QA platform.

At Tezza Business Solutions, I designed and built secure backend APIs for a multi-tenant enterprise QA SaaS platform. I implemented JWT authentication, 16-role access control, and PostgreSQL tenant isolation for regulated financial-sector clients.

At OD Autos, I developed the backend and REST API layer for a production vehicle sales platform serving 100+ active users. I integrated payment services and real-time inventory workflows, reducing average purchase workflow time by approximately 40%.

I also built MpFleet, a multi-tenant fleet management platform with Kafka-driven event processing, and developed a notification microservice using Kafka and SMTP. My experience includes Java, Spring Boot, PostgreSQL, Docker, and Kubernetes.
