The project calls for a backend specialist who can step in a few hours each week to extend and refine an existing codebase. Typical duties will include building and updating RESTful APIs, tuning database queries and schema, and keeping the server environment healthy with routine maintenance and monitoring. The current stack is flexible; Python, Java, or Node.js will integrate smoothly with what’s already in place, and I’m happy to adapt to the language you are most productive in. Database choice is likewise open—MySQL, PostgreSQL, or MongoDB are all on the table as long as performance and data integrity remain top-tier. Code lives in Git, tasks are tracked in Jira, and communication is handled over Slack. A clean commit history, meaningful pull-request reviews, and clear documentation are the primary acceptance criteria for every milestone. If you can reliably deliver these within an agreed-upon schedule of part-time hours, let’s get started.
