Make a system safe to change again
When every release feels risky, the cause is usually the architecture. I modernize in slices, in production, instead of the big-bang rewrite that never lands.
What you get
What I deliver
Migration in slices
On ClassCharts I rebuilt a jQuery front end in React in place, as separate micro apps, and moved the mobile apps to React Native while the product stayed live and kept shipping. One seam at a time.
Reliability you can measure
Query and caching work, load-path profiling, and the monitoring to show whether it worked, so the gain survives the next feature.
Infrastructure and CI/CD
Containers, pipelines, automated tests and safe releases, plus cloud migrations. I helped move a production platform from Rackspace to GCP to AWS and led the migration of 40+ TB of assets with the platform up.
How it works
Map
Read the codebase and find where change is actually expensive
Seam
Pick the first slice that can move independently and prove the pattern
Migrate
Move slice by slice with tests and monitoring, production stays live
Hand over
Document the pattern so your team can continue without me
