Profile: https://flows.cv/shikharmattoo

I’m a full-stack engineer who enjoys building practical software and taking responsibility for it once it’s in production.

I’ve worked on systems that range from internal enterprise platforms to user-facing products used by thousands of people. What I enjoy most is owning problems end-to-end understanding what users need, building the feature, and then improving reliability, performance, and cost once real traffic hits the system.

Recently, I’ve been working on Illinois.Chat, an AI assistant used by over 10,000 students and faculty. As one of the founding engineers, I helped design and build the full stack, worked on document ingestion and retrieval, and focused heavily on making the system stable and predictable in production. A lot of my time went into reducing failures, improving response quality, and keeping the system fast and affordable to run.

Before that, I spent time at Infosys building backend systems for financial risk platforms. That experience taught me how to write maintainable code, work in structured engineering environments, and think carefully about data, performance, and operational reliability.

I value clear communication, ownership, and teams where engineers are close to the product and its users. I’m always learning, but I prefer learning by building real things and shipping them. If you’re working on products with real users and real constraints, I’d be happy to connect.
