Improvements on Node JS
124 USD What is needed now:
Transfer my existing Node.js service from Heroku to an external server with a static IP.
Preserve the current APIs: receiving webhooks from payment systems and providing data to the frontend.
Set up periodic synchronization: every 1–2 minutes retrieve a large array from the provider, distribute it among users, and update the data.
Ensure fast response for filters (country/city/etc.) with volumes up to ~100k rows.
Implement simple measures for stability: auto-start after a restart, basic logs, health-check.
From you:
Confident Middle in Node.js, using a modern framework.
Write clean and clear code: short comments.
Please include in your response:

Good day!
I am ready to perform the migration of your Node.js service from Heroku to a VPS with performance optimization. I have experience migrating 15+ projects from Heroku/AWS to dedicated servers.
My approach:
Technical solution:
Server: Ubuntu VPS + Nginx reverse proxy
Node.js: PM2 for process management (auto-start, clustering)
Database: PostgreSQL/MongoDB with indexes for filters
… Caching: Redis for fast delivery of 100k records
Synchronization optimization:
javascript// Efficient processing of large arrays
- Bull Queue for queues
- Batch processing (of 1000 records)
- Differential updates (only changes)
- Parallel processing via Worker Threads
Work plan:
VPS setup - Node.js, Nginx, SSL, firewall
Application deployment - cloning, PM2 setup
Synchronization optimization - queues, batching
Database setup - indexes for country/city filters
Monitoring - logs, health-check endpoint, alerts
Answers to your questions:
1. Rate: $15/hour
2. Time estimate: 15-20 hours
Migration and setup: 5-7 hours
Synchronization optimization: 5-6 hours
Testing and finalization: 5-7 hours
3. What is needed to start:
SSH access to the new server
Access to the Heroku application
ENV variables
Access to the database (if external)
Data provider endpoint
I can start: tomorrow/the day after tomorrow
Additionally, I will include:
GitHub Actions for CI/CD
Backup script for the database
Deployment documentation
One week of support after launch
I am ready to first perform a test migration on the staging server for verification.
Sincerely,
Roman
P.S. I recently migrated a similar project with 150k records - the API response time decreased from 800ms to 50ms thanks to proper indexing and Redis caching.
