About this gig

You built an app with AI and now it's broken. I'm the engineer who fixes it.


Lovable, Bolt, v0, Cursor and Replit are great at getting you to 80%. The last 20%, the part that breaks in production, needs someone who actually knows how software works.


That's me: Senior Software Engineer, 5+ years, production fintech and core banking systems.


WHAT I FIX

Apps that crash, freeze or won't deploy

Broken database connections and Supabase or Firebase issues

Authentication that doesn't actually protect anything

API integrations that fail silently

Security holes: exposed keys, missing validation, open endpoints

Code the AI wrote that nobody can maintain anymore


WHAT I ADD

Features the AI couldn't finish

Real backend logic, payments and integrations

Proper error handling and database structure

A deployment that stays up


STACK

React, Next.js, Node.js, NestJS, TypeScript, .NET, Supabase, PostgreSQL


Honest note: if your app needs a rebuild instead of a patch, I'll tell you that before you order. I don't take money for band-aids that won't hold.


Send me your project link and what's broken.

Senior Software Engineer with 5+ years building backend systems for fintech and enterprise products. Right now I build and maintain a production core banking platform: credit and prepaid cards, Mastercard integrations, loyalty programs. Stack: .NET/C#, SQL Server, Node.js/NestJS, microservices on Docker and Azure Kubernetes with CI/CD. Before that: e-invoicing middleware still used by real companies, ETL pipelines and lending software. What you get: code that runs, honest timelines, and a clear explanation of what was wrong. Message me first. I'll tell you straight if I'm the right fit.
