Platform Maintenance & Enhancements

I run a live SaaS platform built on a Node.js 20, Express.js, TypeScript stack with MongoDB Atlas and a suite of AWS services (S3, SES, EC2). The front end is split between a Flutter user app and a Next.js 15 (React 19) admin panel, with Firebase Authentication handling log-ins.

Most of my pressing headaches sit in the backend: elusive production bugs surface under load, and I need an experienced full-stack developer who can jump straight into that codebase, pinpoint the root causes, and ship robust fixes without disrupting users. Day to day you’ll be:

• Investigating and resolving production incidents in the Node/Express API
• Using (and supervising) modern AI coding tools to accelerate patch generation while keeping quality high
• Profiling queries, tightening memory usage, and improving response times where you see obvious gains
• Adding or refining endpoints and background jobs when a clean solution requires new code
• Coordinating any correlated tweaks in Flutter, Next.js or our AWS/Firebase infrastructure so the whole system stays in sync

I handle product direction, so you’ll have clear tickets and the freedom to choose the best technical approach. Clean Git commits, concise PRs, and thoughtful code reviews are the acceptance criteria I look for before merging. If you have a track record of stabilising complex Node backends and enjoy blending your own expertise with AI assistance for rapid delivery, I’m ready to collaborate.
