Scaling a PHP ERP from 80 to 1,000+ Concurrent Users
Client: Enterprise Client — Onest Tech LLC · Enterprise Software / Manufacturing
The flagship ERP product was hitting a ceiling at ~80 concurrent users. Response times degraded sharply under load, and the instinct from stakeholders was to rewrite the entire system in microservices — a 12-month project. As Tech Lead, I pushed back and proposed a profiling-first approach before any architectural changes.
CI/CD Pipeline Rollout Across a 36-Person Engineering Team
Client: Internal — Onest Tech LLC · Software Development / DevOps
A 36-developer team across 8 concurrent projects was deploying manually via SSH. Staging was perpetually broken, deployments took 45+ minutes, and post-deploy incidents were frequent. Two previous attempts to introduce automation had failed because they tried to change too much at once, causing developers to bypass the pipeline entirely.

The challenge was designing a database-per-tenant architecture that could scale to 200+ tenants while keeping migration orchestration and connection pooling manageable.
