About

Dhanendra Kumar — software engineer

A decade of Java, Spring Boot, MongoDB, and the small details in between.

I write here when I figure something out that I would have liked to read myself. Posts lean toward backend topics — the JVM ecosystem, data modeling, the small operational details that take a week to learn and ten seconds to forget.

Stack I work with

  • Languages: Java, Groovy, TypeScript, a little Kotlin
  • Frameworks: Spring Boot, Grails, SvelteKit (this site)
  • Data: MongoDB, PostgreSQL, occasionally Oracle
  • Ops: Docker, GitHub Actions, GitLab CI

Outside of work

Motorcycling and long rides — the longest so far was a nine-day trip to Leh and Ladakh. Photography along the way. Trance and rock when I'm coding.
