Project details
Built fast, now needs to work properly?
I’ll production-harden your AI-built, founder-built, or vibe-coded app by cleaning up fragile flows, fixing key issues, and reducing launch risk.
This is for existing React / Next.js / TypeScript web apps that already run, but feel messy, unstable, or hard to trust. I focus on practical hardening work: bug fixing in critical paths, validation and error handling, API and integration cleanup, maintainability improvements, UI polish in touched areas, and testing where appropriate.
This is a strong fit for rushed MVPs, SaaS products nearing launch, or internal tools that need senior cleanup before handoff. This is not a full rewrite. The goal is to make the app safer, cleaner, and easier to ship.

Prediction Market SaaS MVP Triage & Bug Fixing
Benji is great to work with, he is very detailed & has excellent knowledge of SasS & backend & frontend technologies. He quickly got up to speed in my codebase, fixed all issues. Hope to work together again in the future.
About Benji
Senior Full-Stack SaaS Engineer | React, Next.js, Node.js, Expo
Dublin, Ireland - 9:47 am local time
I’m a senior full-stack developer with 10+ years of experience shipping customer-facing web and mobile products across React, Next.js, TypeScript, Node.js, Python, APIs, authentication, payments, backend workflows, and React Native / Expo.
I’m strongest when a product already exists, but needs the engineering work required to make it stable, secure, maintainable, and ready for real users.
I can help with:
- SaaS MVP completion and production hardening
- React / Next.js bug fixing, feature work, and refactoring
- Full-stack TypeScript / Node.js development
- Stripe, OAuth, SDK, API, and third-party integrations
- Auth flows, permissions, secure user journeys, and backend workflows
- Stabilising rushed, fragile, or messy codebases
- React Native / Expo mobile app development
- Release preparation, debugging, QA, and technical cleanup
I’m most useful when you need more than someone to blindly complete tickets.
I can enter an existing codebase, understand the real problems, make pragmatic technical decisions, and ship cleanly without turning the project into a rewrite. I care about getting the product working properly: stable flows, clear architecture, secure data handling, reliable integrations, and code that can be maintained after the job is done.
If your SaaS app, MVP, or prototype needs to become reliable, secure, and production-ready, I’m a strong fit.
