About this gig
Hi, I'm Przemek. I have 15+ years in IT and 10+ years delivering software and products.
Did you build an app with Base44, Lovable, Replit, Bolt, Cursor, or another AI/vibe coding tool but now it is broken, unfinished, messy, or not ready to show users?
I can help you fix and finish your AI-built web app.
I can help with:
- bugs, errors, crashes, and broken features
- broken UI, layout, and mobile responsiveness
- Base44, Lovable, Replit, Bolt, and Supabase issues
- authentication/login problems
- database and API issues
- OpenAI / Claude / Gemini / LLM feature fixes
- deployment problems on Vercel, Netlify, Replit, Cloudflare, or similar
- cleanup and refactoring of messy AI-generated code
- basic polish before demo, testing, or early launch
I work best with web apps, MVPs, dashboards, SaaS prototypes, client portals, internal tools, and messy prototypes that need a clear path forward.
My goal is simple: diagnose what is broken, fix the highest-impact issues first, and help you get a usable version ready for demo, testing, or early users.
Please message me before ordering. AI-built apps can vary a lot in quality, so I need to check your current progress.

Hi, I'm Przemek. I help founders and small businesses turn an idea, a broken AI-built app or a messy workflow into software people can actually use, without the agency price tag. I build web apps, MVPs, dashboards, internal tools and business websites, fully custom and on your own accounts, so you own everything. I have 15+ years in IT and 10+ years delivering software and products in complex fintech environments, and I ship my own products too, from a voice AI agent to a deployment platform. Message me with your idea or your app link and I'll come back with a clear plan.

FAQ
Can you fix apps built with Base44, Lovable, Replit, Bolt, Cursor or Claude Code?
Yes. I work inside the existing code, whichever tool wrote it, and fix the cause instead of rebuilding the app. Send me the app, the repo or screenshots and tell me what is wrong.
Do you build full apps from scratch in this gig?
This gig is mainly for fixing, finishing, and improving existing AI-built apps. For a full new app, message me first for a custom offer.
Can you fix Supabase, API, auth, or deployment issues?
Yes. These are good fits for this gig, depending on the current state of the project.
Can you add payment integration?
Yes, but payment work is handled as an extra or custom offer because it usually needs careful setup and testing.
Do I need to message you before ordering?
Yes. AI-built apps vary a lot in quality and complexity. Please message me first so I can check the app, understand the problem, and confirm the right package before you order.
What do you need from me to start?
I need the app link or repo access, the platform used, screenshots or error messages, and a clear list of the top issues you want fixed first. Please do not send production passwords, API keys, or private secrets in chat.
Can you fix Stripe payments or subscriptions?
Yes. Typical cases: the payment goes through but the plan does not unlock, or the webhook fails. Small fixes fit the Basic package; I confirm after a look at the app.
Can you fix Supabase login or database problems?
Yes. Login loops, users who can see each other's data and broken database rules are common in AI-built apps and fit this gig well.
Can you be my consultant while I keep building with AI?
Yes. I can review what the AI tool built, tell you what to fix first, and give you the next steps in plain words. Many clients come back for this between fixes.
What if the problem is bigger than the package?
I tell you what causes it and what is left, with a clear price for the rest, before you pay for more. You decide if we continue.
