Project details
I will integrate Stripe, OAuth, or a third-party API into your existing web app. Whether you need payment flows, authentication, webhook support, or service-to-service integration, I’ll implement the agreed flow cleanly within your current codebase and provide a clear handover when the work is complete.
This service is best for teams that need focused, reliable integration work delivered without drama.

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 - 2:14 pm 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.

After purchasing the project, send requirements so Benji can start the project.
Delivery time starts when Benji receives requirements from you.
Benji works on your project following the steps below.
Revisions may occur after the delivery date.
Review requirements and confirm scope
I review the provider, desired flow, and technical requirements, then confirm exactly what will be implemented.
Inspect the codebase and integration points
I review the relevant frontend, backend, and existing service connections to identify the cleanest implementation path.
