All case studies, capabilities, integrations, playbooks, and field notes tagged with modernization.
Case study
How I moved a legacy shipment dashboard from 80-90 second load times to under 2 seconds using SQL preprocessing and a React/TanStack rebuild.
Playbook
Step-by-step playbook for refactoring legacy logistics code safely: characterization tests, strangler patterns, and rollback-ready delivery.
Case study
Mapped runtime usage, added feature switches and rollback guards, then removed deprecated PHP modules in waves—reduced ambiguity and maintenance risk with zero operational regressions.
Case study
Upgraded credential hashing, stabilized password recovery, and aligned frontend/backend validation in a mixed PHP/React stack—improved security and reduced support friction without locking out active users.
Field note
After years modernizing messy PHP, jQuery, and COBOL-adjacent logistics platforms, I learned that the ugliest code often contains the most valuable business truth. Here's what greenfield engineers miss.
