About this gig

A broken feature, API error or failed webhook can stop an otherwise working app.


I diagnose and fix a defined issue in your existing application. I work with React interfaces, JavaScript and TypeScript services, Python backends, databases and third-party APIs.


I can help with frontend errors, login and data-flow issues, backend behavior, API failures and webhooks. I also assess incomplete or AI-generated code after reviewing the actual application.


You receive the source-code patch, focused checks and clear handover notes.


Basic: one confirmed small bug in a component or endpoint.

Standard: one backend or integration repair, up to 2 endpoints.

Premium: one existing flow, up to 2 screens, 3 endpoints and 1 database.


Send what is broken, what should happen and your stack before ordering. If the cause is unclear, a $75 diagnosis provides findings and a repair proposal. That fee is credited against my quoted repair total if you continue. New features and full rebuilds need a separate scope.

I'm a backend and integration engineer building AI tools, WhatsApp workflows and web applications. I develop custom MCP servers, connect business APIs, and repair broken application flows. My work includes native WhatsApp catalog and cart integration, payment and order workflows, wallets and developer SDKs. I work with TypeScript, JavaScript, Python, Rust and Go. I define the result before building, test the agreed flow, and provide clear source code and handover notes. Send me your current setup and the outcome you need.
