About this gig

Does your web app look finished, but a form, button or calculation still fails?


I investigate a reproducible JavaScript issue, repair the agreed problem and test the original steps again.


Examples: incorrect totals, form validation, duplicate submissions and broken frontend workflows in custom HTML, CSS and JavaScript apps. Existing frameworks and AI-built apps are assessed before ordering.


BASIC: 1 pre-reviewed minor issue on 1 page.

STANDARD: 1 agreed form workflow across up to 2 pages, with regression checks.

PREMIUM: Up to 3 related defects in 1 workflow across 3 pages, tests and 1 agreed deployment after approval.


Delivery includes changed source, an explanation and test notes. A protected test preview is arranged where feasible.


Message me BEFORE ordering with the URL, reproduction steps, expected result and redacted screenshots. Source access and permission to modify it are required. I will confirm feasibility and scope first.


Hosting and third-party fees are separate. New features, rewrites, migrations, security certification and ongoing support are excluded. Revisions refine the agreed repair.

I build practical web apps for service businesses: quoting calculators, job dashboards and focused internal tools. My original calculator and job-workspace demos show how inputs, records and everyday tasks can fit into a clear, responsive interface. We start with your process, approved business rules and a small agreed scope. Packages range from a sample-data prototype to a web app with login and saved records. Send a redacted spreadsheet or sketch, your must-have result and timeline before ordering.
