About Me

Hey there! I'm Rishi Selvakumaran, a passionate Software Engineer at Hughes Network Systems. I thrive on building robust, distributed full-stack applications using Java, J2EE, Spring, and Angular. With hands-on experience across teams at Hughes, Miovision, and the University of Minnesota, I’m skilled in Agile and Scrum methodologies and have designed systems for a variety of applications. I’m always eager to dive into new technologies, currently pursuing certifications in CKA and AWS DevOps. I love collaborating on innovative projects and am always open to exciting opportunities—let's connect!

Why me?

Passion Meets Expertise
What sets me apart as a software engineer is my deep passion for technology combined with a strong technical foundation. I don’t just write code—I build solutions that solve real-world problems. Whether it's developing full-stack applications or migrating systems to microservices, I approach every project with a drive for excellence and a commitment to innovation.

Customer-Centric Mindset
I believe that the best software is built with the end user in mind. From enhancing system performance by 40% at Hughes to optimizing features for real-time user needs, I am always focused on delivering value. My development process revolves around understanding and prioritizing customer requirements, ensuring that every decision I make improves user experience.

Ownership and Responsibility
I take full ownership of the work I do, from ideation to final deployment. My leadership in transitioning legacy systems to microservices at Hughes has not only improved scalability but also earned trust from stakeholders. I believe in taking responsibility for both success and learning, always aiming to exceed expectations.

Action-Oriented Problem Solver
I thrive in fast-paced environments where quick, decisive action is needed. Whether it’s streamlining deployments with automation scripts or mentoring junior developers to deliver at their best, I don’t wait for problems to be solved—I actively tackle them. My bias for action drives me to find efficient, effective solutions without compromising quality.

Innovating Through Complexity
What excites me the most about software development is the challenge of simplifying complex systems. From optimizing batch processing algorithms to securing API endpoints, I embrace innovation and never settle for “just good enough.” I thrive in environments where pushing the limits of what’s possible is the norm, and I’m constantly seeking ways to refine and elevate my craft.
