About this gig

Turn one small task into a browser tool with a clearly defined set of inputs and outputs. Examples include a quote calculator, a checklist or a simple estimator using rules you supply.


Basic: one screen, up to 5 inputs, one calculation flow.

Standard: up to 2 screens and 10 inputs, with result export as CSV.

Premium: up to 2 screens and 15 inputs, CSV import and export, plus local browser storage.


You receive HTML, CSS and JavaScript source files, setup notes, agreed example checks and one revision within scope.


No user accounts, payments, server database, sensitive data, medical or financial decision systems, external APIs or hosting are included. Local storage stays in the browser and is not a shared database.


Before ordering, send the exact rules, sample inputs and expected results. I will check feasibility and confirm the scope. Complex products and undefined features need a separate assessment.

Hi, I'm Can, based in Germany. I coordinate small digital projects with a clearly agreed scope: responsive web pages, simple browser tools, practical file-processing scripts and German product copy. I use a tool-assisted workflow, review the result against your brief and provide the agreed files with setup notes. My focus is on small, understandable solutions. Send your goal, examples and constraints so we can define a suitable deliverable before work starts.
