About this gig

Stuck on an old Angular version? I upgrade Angular apps safely without breaking what already works.


6+ years in production Angular across fintech, healthcare, and marketing SaaS, including AngularJS > Angular migrations and multi-version jumps (v11v21+). Version upgrades are a shrinking-specialist niche most devs avoid them. I don't.


I handle:

  • Minor & major Angular version bumps (e.g. v14 v17)
  • AngularJS modern Angular migration planning & execution
  • Dependency / RxJS / TypeScript compatibility fixes
  • Deprecation cleanup and build/tooling updates


Why it matters: an outdated framework is a security and hiring risk. I get you current with a tested, incremental upgrade and a short report of what changed.


Message me your current version, target version, and app size before ordering I'll scope it and quote accurately, free.

I fix, build, and modernize production web apps. 6+ years of engineering across fintech, healthcare, and marketing SaaS. Angular is my depth (v11–v21, RxJS, NGXS), and I also ship in React, Next.js, Vue, and Node — I can own a feature from API to UI when needed. I deliver the fixes and features that need a careful, experienced hand: state tangles, broken forms, performance, small features, and version upgrades, without breaking the rest. Message me before ordering — I'll look for free and tell you the real scope. Not happy with the first result? I revise until it's right.
