About Aman Kumar

I used to think being a great engineer was just about writing clean code.8 years later and after scaling and building performant systems at Microsoft and now also building AI tools, I know it’s about impact.I am a Senior Software Engineer at Microsoft, where I work on complex web applications (like Excel) and build AI tools that automate user/developer scenarios. I’ve gone from an intern at a startup to shipping code that impacts millions of users globally.Over the years, I’ve worked on:– Scalable web platforms– Performance-critical systems– Distributed services used at massive scale– AI-powered tools and developer productivity solutionsI have been working on solving complex problems across multiple hubs like M365, Outlook, Teams and bringing consistent user experience for Excel across these hubs and improving performance across these hubs for Excel while collaborating with multiple teams.Recently, I’ve been deeply focused on AI engineering building AI tools, agents, and automation systems that improve both product quality and developer productivity.I use or have used various technologies, such as React, JavaScript, TypeScript, Angular, Java, Spring, Spring Boot, SQL, MongoDB, Cassandra, Docker, Kubernetes and Python, to create user-friendly and scalable solutions.I also actively help: Students & professionals crack Big Tech interviews Engineers understand system design the right way Developers use AI effectively (not blindly)I regularly share:– Real interview insights– Career lessons from Big Tech– System design breakdowns– AI workflows engineers actually use in production If you’re:– Preparing for Big Tech interviews– Looking to build scalable systems or AI tools– A founder/startup needing engineering guidanceOutside of my full-time role, I enjoy exploring ideas, building small tools, and discussing engineering and AI problems with founders and teams.
