Who Am I?
Hey there! I’m Lalith Kumar Rajendran, a Software Engineer with a knack for turning complex challenges into seamless solutions, and yes—I actually enjoy it! With 4 years of hands-on experience, I’ve delved deep into backend development, scalable microservices, and DevOps. My journey began at Cognizant, where I played a key role in modernizing 7-Eleven’s order processing system, turning it into a high-performing and scalable, microservices-based architecture. That’s where I got my thrill for optimization—whether it was reducing server load or ensuring smooth data integration. Then came my internship at Rivian, where I shifted gears to the world of automation and cloud infrastructure. From automating CI/CD pipelines to improving system observability with Prometheus and Grafana, I got my hands dirty in making sure everything runs like a well-oiled machine. I love digging into problems and streamlining processes so they just work kind of like those satisfying moments when all the pieces of a puzzle finally click together.
What drives me?
Building scalable systems that don’t just solve today’s problems but anticipate tomorrow’s. I’m always excited to take on challenges where technology can make life easier for users and businesses alike. What demotivates me? Stagnation—I'm all about continuous learning and pushing the envelope. I believe in teamwork, and collaboration isn’t just a buzzword for me. I thrive on it, whether it's collaborating with cross-functional teams or mentoring peers. At the end of the day, what keeps me going is knowing that I can make an impact by not just solving problems, but creating solutions that last. Let’s build something awesome together!
