Have a web app or AI-built prototype with a blocker or an unfinished feature? I can review the relevant implementation, define the next practical change and help complete it. That might be a broken login flow, an unfinished dashboard, a backend feature or an integration that needs connecting. Share what works today, what fails or is missing, how the app was built and whether you control the code and accounts. We will agree the investigation scope first. If the work is feasible, I will quote the specific fix or feature with an acceptance check and handover. Delivery dates are agreed in the quote; larger projects use separate milestones. I do not promise to repair an unknown codebase before reviewing it. Complete rewrites, security certification, ongoing support and provider fees are agreed separately. Relevant shipped work and authentication integrations: onmax.me/work and github.com/onmax.
