About Me

I am a Senior Software Engineer specializing in designing and scaling Java and Spring Boot architectures. Over the past several years, I have focused on building resilient Microservices and engineering robust Enterprise Platforms that handle high-throughput, mission-critical workloads.

Beyond core backend development, I have extensive experience leading complex Cloud Migrations and orchestrating deployments using Kubernetes and AWS. I build reliable data layers with PostgreSQL and am currently exploring the intersection of modern infrastructure with Gen AI and Agentic AI to unlock new engineering capabilities.
