Hello
Something is broken and nobody can find why. The original team is gone. You inherited code that fails with no obvious place to start. I find the root cause, fix it, and hand back a write-up a non-technical owner can follow.
First consult is free · Time estimate and price agreed before any work starts
It is broken, but nobody knows where
Thousands of log lines, errors that point at the wrong place, and several failed attempts already.
The original team is gone
Nobody left can explain this codebase, there are no docs, and nobody wants to touch it.
It gets fixed, then comes back
Past fixes treated the symptom. Under real traffic the same failure returns.
Balances are off, transactions vanish
Anything touching money has no margin for error. You need to know exactly where data is lost.
The job is not done when the bug disappears. You also learn what happened and how to keep it from returning.
A written report on what caused the problem and how it happened — in plain language, not a raw stack trace.
What I changed and why I chose this approach over the alternatives, so your team can build on it.
Recommendations to stop it recurring — what else is worth hardening and what to keep an eye on.
Fixing systems that are already live — web, mobile, money flows and servers.
Frontend / Backend
iOS / Android
Fintech / Payment
Server / DevOps
Starts with a free conversation and an estimate. Nothing is charged until we agree on scope.
Free to talk, nothing charged yet. Screenshots or partial logs are enough to start.
You get a clear time estimate and price to approve before any work begins.
Only the access needed for the fix. Happy to work on a separate branch so nothing live is touched.
Patched code plus a report on the cause, the fix, and how to prevent a repeat.
Want something tweaked after handover? We can sort it out within what we agreed.
Pick by how complex the problem is. Not sure which one fits? Ask me first.
hours
A single bug where you roughly know where it lives
Choose this package →5hours
A bug that has to be traced before it can be fixed
Choose this package →10hours
Several bugs at once, or a large and complex system
Choose this package →If the fix takes less time than booked, the remaining hours carry over to your next job.
If the same bug returns within 7 days of handover, I fix it free.
I am a full stack developer with over 5 years of experience, more than 4 of them in fintech.
I built trading and brokerage systems where precision is non-negotiable and data cannot be wrong. That work means tracing failures inside complex systems with data moving constantly — and finding the real cause rather than making the error message go away.
Yes — tracing the root cause is the core of this service. Send the symptoms and whatever logs you have, and I will tell you roughly how long it should take.
Only what is needed for the fix. Temporary access or a separate branch works fine, and I am happy to sign an NDA.
I estimate the number of hours after a first look at the symptoms and confirm it before starting. Nothing gets added mid-job without telling you first.
Nothing is wasted — the remaining hours carry over to your next job.
If it is the same bug and it returns within 7 days of handover, I fix it free.
This service focuses on fixing existing systems. New features or new builds can be scoped as a separate job.
No preparation needed. Tell me what happened and what errors you are seeing, and I will help work out where it is stuck.
