I'm a backend Engineer with around ten years of experience building cloud-native systems, backend platforms, and AI-enabled products across healthcare, IoT, and enterprise environments. Over the last several years, my work has become strongly focused on the areas that overlap with DevSecOps: secure cloud architecture, CI/CD, containerization, infrastructure reliability, API security, tenant isolation, event-driven systems, and compliance-sensitive environments. In my current role at Concentrix, I work on an AI healthcare assistant platform where security, reliability, privacy, and operational resilience are absolutely critical. I’ve been involved in modernizing legacy systems into microservices, improving platform reliability on Azure Kubernetes Service, implementing secure integrations with healthcare systems, and making sure the platform handles sensitive data in a compliant and production-ready way. Before that, at Synox, I worked on a multi-tenant IoT SaaS platform where I was responsible not just for backend and frontend delivery, but also for cloud deployment, CI/CD, Docker-based services, tenant isolation, RBAC, API protection, and secure device and platform communication. So even though my title has often been software engineer or full-stack engineer, a large part of my actual contribution has been very close to DevSecOps in practice
