I build software that
works in the real world.

I’m Keshav Singhal, a software engineer focused on secure, scalable enterprise applications, backend systems, APIs, and modern product experiences. I turn complicated workflows into software people can actually rely on.

01 / About

Engineering depth.
Product mindset.

My work sits where backend engineering, business-critical workflows, security, data, and user experience meet.

I currently build enterprise applications for Ohio’s education ecosystem, working across Java, Spring Boot, Vaadin, Hibernate/JPA, PostgreSQL, authentication, scheduling, reporting, APIs, testing, and CI/CD.

I enjoy the parts of software engineering that require both precision and ownership: debugging difficult production behavior, modernizing legacy systems, designing maintainable APIs, and shipping features end to end.

02 / Experience

Built in production,
not just in tutorials.

Building something
ambitious?

I’m interested in engineering teams working on difficult, high-impact products — especially backend, platform, full-stack, AI infrastructure, developer tools, and cloud systems.
