I will audit and refactor your project codebase to production grade standards
Dmytro K
About this gig
Codebases grow fast. Quality doesn't.
Three devs, no tests, no docs, nobody sure what half of it does. You want to ship a new feature and you're scared to touch the existing code. Because last time something broke in production at 2am.
That's not a code problem. That's a standards problem.
I've audited and refactored production React apps at HSBC, cleaned up legacy migrations at Bottomline, and maintained full test coverage across complex SPAs at UBS. 13 years of knowing exactly what "production-grade" means under real pressure.
What you get:
- Full codebase audit what's broken, what's risky, what needs to go
- Refactored code clean architecture, no spaghetti, no shortcuts
- Test coverage Jest/Test-library, TDD/BDD where it matters most
- CI/CD setup so your team ships with confidence, not anxiety
Clean Code. Real Tests. Zero Shortcuts.
Message me before ordering I'll review your repo first and tell you exactly what needs fixing.

Building a FinTech product that needs to work on day one?
I've shipped trading dashboards at HSBC, financial tools at UBS, CRM platforms at Publicis Sapient, and SPAs for McKinsey and Sainsbury's. 13 years. Not side projects. I build things that scale cleanly from day one. I know what breaks when it's done wrong.
What I build: trading dashboards · portfolio apps · data-heavy SPAs · legacy migrations (jQuery→React, Excel→Web).
Stack: React · TypeScript · Next.js · Node.js · PostgreSQL · AWS.
EU timezone. Senior team available for full-cycle delivery.
