As a Software Engineer at Viasat, a global communications company, I develop and maintain microservices for managing modem link configurations and network links, integrating data distribution via Kafka and enhancing system resilience and performance.

My core competencies are Java and Spring Boot, but I am also familiar with Go, React, NextJS, OpenAI Apis, and Docker. I am passionate about solving complex problems, delivering innovative solutions, and collaborating with diverse teams. I believe I can bring my domain expertise, skills, and experiences to any team and contribute to the company's growth.
