About this gig

I help businesses build custom API integrations when documentation is limited, outdated, or not enough for the workflow they need. I can analyze authorized web app or system flows, understand request behavior, payloads, sessions, tokens, and authentication logic, then build a clean backend integration, API wrapper, or automation service.


I only work on systems you own, manage, or are authorized to access. I do not bypass security, access private data, or break platform rules.

Backend engineer with 8+ years of experience building backend systems, API integrations, and automation for business and financial workflows. I specialize in undocumented APIs and mobile/web app flows, then turning that into clean, secure middleware and automation. I work async-first with written documentation and clear updates, and I deliver a working trial or MVP within 4–8 hours of receiving clear requirements, so you can validate the approach before committing to a full build. Available 11 AM–11 PM GMT+7.
