About Me

A snapshot of who I am and what drives me

I'm a Senior Software Engineer at Capgemini with 2+ years of experience building enterprise-grade backend systems. I specialize in Java and Spring Boot, working with microservices architecture, API gateways, Kubernetes deployments, and production systems for large-scale platforms.

I drive backend development and API gateway modernization initiatives, designing secure REST APIs and managing Kong and Axway gateway platforms. My work spans production stability, CI/CD pipeline optimization, and building reliable distributed systems.

Currently, I'm actively strengthening my Data Structures & Algorithms and System Design skills to grow into SDE / SDE2 backend engineering roles. I enjoy discussing backend engineering, scalable APIs, and distributed systems architecture.
