Case Study
Legacy Next.js Replatform
A high-risk migration where uptime constraints blocked full rewrites.
Problem
Deployment breaks, weak module boundaries, and unowned release decisions caused frequent hotfix cycles.
Solution
- Defined domain boundaries and migration sequence
- Introduced release checklist with build, smoke, and rollback gates
- Shifted risky integrations behind feature flags and staged rollout
Result
Release failure rate dropped by 58% in 5 weeks. Production freeze windows were removed for standard releases.
Role
Architecture lead, release governance design, migration execution support.
Tech Stack
Next.js, TypeScript, PostgreSQL, Redis, Nginx, GitHub Actions.
Proof
Release reports, incident logs, and gate compliance records were delivered to stakeholders weekly.
Lessons & Tradeoffs
A phased migration took longer than a big-bang rewrite, but preserved uptime and reduced organizational risk.
