About this gig

Stuck with a failing Docker build, port conflict, broken reverse proxy, or Node.js runtime crash? 


I diagnose and resolve microservice issues, container conflicts, and backend bugs quickly and cleanly.


What I Fix & Optimize:

Docker Compose networking, port mismatches, and exit codes (137, 1)

API gateway rewrites, reverse proxies, and CORS errors

Node.js & Express crashes, undefined middleware, async errors

PostgreSQL connection pool exhaustion and migration locks

Volume mounts, rebuild scripts, and environment configs


Supported Tech:

Docker, Docker Compose, Node.js, Express, Next.js, PostgreSQL, Redis, Linux/Ubuntu.


Why Work With Me?

Fast turnaround (often resolved within hours)

Clear root-cause explanation so the bug doesn't return

Clean Git commits and zero data-loss guarantee

Unlimited revisions for your peace of mind


How It Works:

1. Message me with your error logs or docker-compose.yml.

2. I identify the failure point and confirm the solution.

3. I fix, test, and document the resolution.


Please message me before placing an order so we can review your logs and get your system running immediately!
