About Me

Hi, I'm Lekshmi Kolappan — a seasoned SRE/DevOps Engineer with over a decade of experience building reliable, scalable infrastructure. I specialize in AWS, Kubernetes, Docker, and Linux, with expertise in automation and observability.

At Adstream Inc., I drive observability and performance monitoring initiatives. Previously at ADP Inc., I led DevOps transformations that cut release times by 20% and built enterprise-grade infrastructure frameworks.

Beyond tech, I'm passionate about photography, books, and sharing insights through my tech blog. I thrive at the intersection of systems thinking and creative problem-solving.
