freelance java/mysql coder (part-time) jobs



Feature Upvote helps product managers track feature requests. It is a SaaS, built as a traditional multi-page web application.

We’re self-funded, profitable, and sustainable. When you work with us, you get a stable and predictable long-running engagement, in a low-stress environment.

About the engagement:
  • Initially 1 day/week (32-40 hours/month), with occasional additional days according to our needs
  • 6 month engagement, moving to an ongoing commitment if both sides are happy with the initial engagement
  • Fully remote
There is a chance of increasing the monthly hours in the future, but this is not something we can promise.

The current Java code was mostly written by the founder over the last four years.

Things you’ll do:
  • Regularly update dependencies
  • Fix bugs
  • Code new features and improve existing features
  • Clean up the existing code

Our tech stack:
  • Java 8 - although perhaps with your help we’ll move to Java 11 soon
  • MySQL
  • Redis
  • Spark - a lightweight Java web framework
  • Freemarker
  • Jdbi
  • A light scattering of JavaScript
  • AWS - for hosting
  • Maven - for building and dependency management

The two skills you need expertise in are Java and MySQL. Everything else is a nice-to-have, and can be picked up on the job.


Tools we use:
  • GitHub - for version control
  • Jira - issue tracking and product management
  • Slack - because sometimes synchronous communication is necessary
  • Email - the preferred way to communicate
  • Notion - for internal docs
