About this gig
Hi, I'm Suliman. I build production backends in Rust and Python for a living, and I use Claude Code and Cursor daily, so I know how they go wrong.
Re-prompting an app until the error disappears is not a fix - it hides the bug until it comes back with a customer attached. I read the code first.
Then I tell you what is actually broken:
- Works in preview, breaks live: env vars that never reach the deployed app
- Login that spins forever: a missing policy on profiles, or a localhost Site URL
- FastAPI or Django endpoints that check who you are, never what you own
- Supabase RLS missing or left as USING (true) - your anon key reads every row
- Your service_role key compiled into the client bundle
Every order starts with a ranked report in plain English. You keep it either way, and you choose what gets fixed. If a rewrite is cheaper, that goes in the report, not on your invoice.
Nothing is open-ended. Nothing starts until you give me read access to the code.
English and Arabic, both native.
125 projects delivered, 100% on-time, 5.0 from 104 reviews.
Message me with what broke and I'll come back with a real estimate, not a template.

Hi, I work in two connected lanes: production backend engineering in Rust (APIs, real-time systems, event-driven architecture) and blockchain development across Ethereum and Solana (smart contracts, tokenization, on-chain data infrastructure). Django/Python available for teams on that stack. Certified in Smart Contracts and Dapps. 122+ projects delivered, 5.0 rating, 100% on-time delivery. Tell me what you're building, and I'll tell you honestly if it's a fit.
FAQ
Why does this cost more than a $20 fix?
Because $20 and a one-day turnaround does not buy a read of your codebase. It buys a change that makes the error message go away, which is not the same as removing the cause. I read three surfaces - auth, data access and the money path - find the cause, and write it in plain English.
I don't know which package I need. What should I buy?
Buy the report - unless what is broken is blocking your users. Then message me, book the 60-minute call ($95, usually within a day), or add the emergency slot ($120) and I start within 24h. Standard's blocker is agreed by message first. The report: one thing to fix today, plus a fixed quote.
Is this backend only? My problem shows up on the screen.
A white screen or a hang is usually a backend fault surfacing in the UI, so I fix it where it starts. Works in preview, breaks live? Standard plus the deploy extra, $490 over 8 days - it can only be proven where it breaks. Need it sooner? Add the emergency slot ($120) and I start within 24h.
What if my builder won't give me the code?
Message me before you order - some projects can't be worked this way, and I'd rather tell you now than cancel later. Lovable and Bolt export to GitHub, and a free GitHub account takes five minutes; Cursor and Claude Code already have a repo. A zip or project invite covers the report only.
What access do you need, and what happens to my code?
Read access only, never a password - Fiverr's rules forbid us exchanging credentials. A collaborator invite to the repo, or a zip, plus a read-only invite to Supabase or your host. I delete my copy once the order closes and I don't discuss your project.
