I will fix, complete and launch your lovable or vibe coded saas
Alexander K
About this gig
You built your SaaS in Lovable, Bolt, Replit, Cursor or Base44. Then auth started breaking, Stripe stopped charging people, features stayed unfinished, and deployment kept pushing launch back.
I take over the codebase, find the real cause, finish the missing work, and get it into production for real users.
What I usually get called in for:
- bugs and broken flows that keep coming back
- half-finished features and vibe-coded AI code nobody wants to touch
- auth, database and backend logic
- Stripe payments and subscriptions
- APIs and third-party integrations
- UI, responsiveness and speed
- deployment and production hardening
I am a full-stack developer and SaaS builder. I built one to around $6k MRR, so I care where the product is going, not just whether today's error disappears.
And I work in the actual code. If you keep re-prompting until the error message stops appearing, the bug is still there, it just moved.
How it works:
- Send me the repo or project link and tell me what is blocking you.
- I review it and tell you what the work actually is.
- I fix it, test it, finish it and ship it.
Message me before you order. I need to see the codebase to price it honestly.

I build and improve SaaS products for founders. From early MVPs and AI-built prototypes to production-ready software. My work combines product thinking, UX, full-stack engineering, AI features, billing, analytics and deployment.
I’ve built a SaaS product that reached ~$6k MRR, so I approach projects as products, not isolated coding tasks. I can help you launch a new MVP, rescue an unfinished AI-built product, or add production AI capabilities to an existing SaaS.
I focus on clear scope, strong UX, maintainable architecture and software ready for real users.

FAQ
Should I message you before placing an order?
Yes. Send me the repo or project link, what is broken, and what you need finished. I will review the scope and tell you which package fits or send a custom offer.
What is included in the Basic Targeted Rescue package?
One defined problem or one small feature: a broken flow, deployment issue, API problem, UI bug, or similar fix. If the issue is larger than it looks, I will tell you before you order.
Can you complete my entire unfinished SaaS?
Yes. I can review what already exists, stabilize it, finish missing features, and prepare it for launch. Larger projects usually fit Premium or a custom offer.
What if I do not know what is causing the problem?
That is fine. Tell me what happens, what you expected instead, and what your users experience. Finding the actual cause is part of the work.
Do you only work with Lovable?
No. I also work with Bolt.new, Replit, Cursor, Base44 and similar AI coding tools. Lovable is simply the main focus of this Gig.
Can you work with Supabase or Firebase?
Yes. I can work with an existing Supabase or Firebase backend and keep it when that makes sense. I also work with PostgreSQL and Prisma when the project needs a different setup.
Will you just keep prompting AI until it works?
No. I work with the actual source code, backend, database, integrations and deployment. AI helps me move faster, but it does not replace debugging and engineering judgment.
What if the AI-generated code is too messy to fix?
I will tell you before we start. Sometimes rebuilding one part is cheaper and safer than continuing to patch it. I will explain the tradeoff and let you decide.
Can you add auth, payments, APIs or database features?
Yes. I can build or repair authentication, Stripe payments, subscriptions, backend logic, databases, APIs and other standard SaaS functionality.
What if something I paid for does not work after delivery?
If something from the agreed scope does not work as delivered, I will fix it within the included revisions and support. New features or scope changes are quoted separately.
