The client was running a 15-year-old PHP monolith with no API layer. Order processing, inventory synchronization, and reporting required extensive manual intervention — 90% of operations were manual. Deployment was a multi-day process involving SSH and manual file transfers. Peak season failures were routine.
We applied the Strangler Fig pattern to incrementally replace the monolith with Node.js microservices on AWS. Each business domain (orders, inventory, reporting) was extracted as an independent service with its own database. n8n automation replaced all manual data sync and reporting workflows. Japanese-speaking PMs managed all client communication and requirements gathering.
🇯🇵 Japanese Summary
We migrated a 15+ year old PHP monolith to Node.js microservices using the Strangler Fig pattern. 90% of manual operations were automated and the migration was completed with zero downtime. A Japanese-speaking PM managed the entire project, providing smooth communication from requirements gathering to delivery.
NKKTech's team delivered exactly what we needed — zero downtime migration that our internal team couldn't achieve alone.
