Yamini Arunachalam — Senior Software Engineer
When I'm not architecting distributed systems that scale to thousands of requests per second and generate millions of dollars, you can find me doing book reports and math problems with my daughter — sometimes even without AI. I'm a Senior Software Engineer with 14+ years of experience building scalable distributed systems on AWS. I've worked across the full build/ship/iterate lifecycle in both hands-on and project leadership roles, from tech giants like Amazon to startups like Homeshop.My philosophy: Building systems doesn’t have to mean building complex architectures. Many problems can be solved with simple, well-designed solutions. I believe in starting simple and breaking down complex challenges into manageable blocks. Complexity is often unavoidable, but unnecessary complexity is not. I aim to design systems that are clear, maintainable, and easy to reason about. To me, the real strength of engineering lies in clarity and thoughtful simplicity.
