About Stelr
An independent studio,
built around craft.
Stelr is a one-person studio led by Divyansh Karan. I build React Native mobile applications and Java Spring Boot backends end-to-end — from the first API contract to the final App Store submission.
Founded August 26, 2025
The Founder
Divyansh Karan
Founder · Lead Engineer
Solo developer focused on shipping mobile software that feels considered. I work directly with founders and product teams — no layers, no handoffs, no compromises in translation.
Journey

Established on August 26, 2025 as an independent mobile-first studio in India.

Launched the studio's first production React Native app with a Spring Boot backend within weeks of founding.
Full-stack mobile
Expanded to offer complete full-stack mobile solutions — React Native apps backed by production-grade Spring Boot APIs.
Selectively taking projects
Working with a handful of teams at a time to keep craft and velocity uncompromised.

Principles
Great digital products
are an act of clarity.
Every product I build reflects a commitment to precision, restraint, and respect for the people who will use it long after launch day.
Founded on principles
Stelr began on August 26, 2025 with a single conviction: mobile software and the backends that power them should be made with the same care as anything else worth keeping.
One mind, end to end
Every line of React Native code, every Spring Boot endpoint, and every database schema passes through the same hands. The result is a coherence that's difficult to manufacture with a larger team.
Built to last
I take on a small number of projects each year so each app and its backend get the attention they deserve — and age well long after launch.
