Project details

Your MVP was built fast — maybe with AI tools, Cursor, or a freelancer who moved on. It worked in a demo. But now real users are hitting it and it's falling apart. Auth issues, flaky payments, pages crashing, features breaking every time you touch the code.

We specialize in rescuing these broken SaaS products without starting over. We audit what you have, identify the root causes, and run a structured 4-week sprint to get it production-ready.

What we fix: authentication, Stripe payment flows, database design, API architecture, performance bottlenecks, deployment pipeline, and monitoring. Everything that's stopping your app from handling real users at scale.

What you get back: an investor-ready codebase, secure auth and RBAC, CI/CD pipeline, staging environments, monitoring dashboards, and full documentation with recorded Loom walkthroughs.

Recent result: Rescued an AI-generated SaaS from completely unusable — 5 weeks later, 500+ users and 300+ paid subscriptions.

Tech: Next.js, TypeScript, React, Node.js, PostgreSQL, Supabase, Stripe, AWS/Vercel.

Refactoring and bug fixes for vibe-coded project - production ready Oussama played a critical role in turning our SaaS start up around at a time when the platform was unstable and at risk. He stepped in, refactored the existing codebase, implemented key new features, and brought everything up to a production-ready standard in an impressively short timeframe. His ability to move fast without compromising on quality gave us the stability and confidence we needed to launch and grow. Quite simply, he helped save the project.

Senior full-stack developer specializing in SaaS rescue work across Next.js, TypeScript, and React. Most engagements start with a broken MVP built too fast on Replit, Lovable, or v0, and need to become something real users won't break.

Founders typically show up in one of three moments.
- The first: the MVP works in a demo but nobody trusts it with paying customers. Auth is leaking sessions. Stripe webhooks fire sometimes. The database schema was written in a hurry and every new feature turns into a week of firefighting.
- The second: the app is about to face an audit. A pilot with a bigger customer, a funding round, or an acquisition conversation, and the codebase won't survive due diligence.
- The third: an AI feature needs to ship. A chatbot, a RAG system, an LLM pipeline built on OpenAI or LangChain, and what was a weekend prototype now needs rate limits, monitoring, and a real architecture behind it.

The most common thing to fix: a Stripe webhook that silently drops 5% of subscriptions and no one notices until the MRR chart flatlines a month later.

Over the last two years, rescue engagements have shipped founders to their first paying users, through seed due diligence, and past pilot deployments with enterprise customers.

The Stack
Next.js, TypeScript, React, Node.js, PostgreSQL, Supabase, Firebase, Stripe, OpenAI API, LangChain, FastAPI, AWS, and Vercel. The work tends to be refactoring, hardening authentication and RBAC, fixing payment flows, migrating databases, and writing the tests and CI/CD pipelines that should have been there from day one.

How engagements run
No open-ended hourly coding. Every project runs as a structured 4-week sprint:
• Week 1, The Audit. Deep code review, ending in a written System Health Report and a prioritized roadmap.
• Weeks 2 and 3, The Hardening. Auth secured. Stripe fixed. Data models refactored. Architectural gaps closed before they break at scale.
• Week 4, The Handover. Staging environments, CI/CD, monitoring, and Loom walkthroughs so whoever comes next isn't lost.

The end state: a codebase that passes due diligence, an auth layer worth trusting, and infrastructure that handles 10x growth without a rewrite.
Outside of rescue work, engagements also include building SaaS products from scratch and integrating AI features into existing apps. Chatbots, RAG systems, semantic search, workflow automation, and LLM pipelines that are production-ready instead of demo-quality.

💬 "My project was a total mess, built on Replit by a non-coder, in a way most developers refused to touch. Oussama said 'I love a messy project to tackle,' and he delivered. He refactored an almost unworkable codebase, fixed 300+ items, and got me to launch. 5 weeks later, 300+ paying users." — Annabel F., Founder

Only one or two founders at a time. A deliberate choice, because rescue work is high-trust, and doing it properly for a few beats doing it badly for many.
If your prototype is in trouble, send an invite with a link to the repo. A System Health Report comes back within 24 hours, no charge, no sales call.

Steps for completing your project

After purchasing the project, send requirements so Oussama can start the project.

Delivery time starts when Oussama receives requirements from you.

Oussama works on your project following the steps below.

Revisions may occur after the delivery date.

Week 1 — Audit & System Health Report

We dive into your codebase, map the architecture, and identify every issue. You receive a written System Health Report with a prioritized roadmap of exactly what needs to change and in what order.

Weeks 2-3 — Hardening & Stabilization

We fix the core problems — auth, payments, database, API structure, performance. Tangled code gets refactored into clean modules. Your app becomes stable enough for real users and real traffic.

Review the work, release payment, and leave feedback to Oussama.
