About

Senior Software Engineer with 5 years of experience building and supporting scalable backend systems in high-availability production environments. Currently at AT&T, I maintain and improve a mission-critical 24/7 application processing billions of network performance records daily, where I focus on reliability, scalability, and security. I’ve led security initiatives to protect secrets and sensitive data, optimized operational performance, and contributed to automation and CI/CD improvements across Dockerized deployments. I bring strong hands-on expertise in Java, Spring, microservices, PostgreSQL, Unix scripting, Docker, and Azure, along with solid foundations in data structures and design patterns. I enjoy partnering with stakeholders to translate business needs into practical technical solutions, and I take pride in mentoring engineers and driving quality through reviews and best practices. Recognitions include AT&T’s Connection Award (Technical & Operational Excellence) and Transformer Award (Team Excellence), and Sopra Steria’s Pinnacle Award (Technical Excellence). AZ-204 certified and always keen to learn, improve systems, and deliver measurable impact.
