Lessons from shaping a scalable ERP using service boundaries and multiple data stores.

Key takeaways from ERP delivery:

  • Use clear service boundaries to keep teams and deployments independent.
  • Keep a polyglot data layer when workloads vary across modules.
  • Use CI/CD to reduce manual deployment risk.
  • Document integration points early (API contracts, OData queries, auth).

CI/CD on AWS EC2

2025-09-01

A simple approach to automated testing and deployment with EC2.

A lightweight CI/CD flow I used for production work:

  1. Validate build and run tests on each merge.
  2. Package artifacts and push to the EC2 deployment target.
  3. Run database migrations and health checks.
  4. Monitor logs and roll back quickly if needed.
