About this gig
Need a custom web tool, calculator, dashboard, or interactive browser app? I can build a clean, responsive, custom-coded solution using HTML, CSS, and JavaScript.
This gig is best for:
Custom calculators
Interactive tools
Simple dashboards
Data visualizations
Frontend web apps
Educational or technical tools
Small browser-based utilities
My main project, Horizon 87, is a browser-based astronomy and mission-planning app with planetary calculations, eclipse detection, planet alignment tools, and porkchop plot visualizations. That project gave me experience building technical, data-heavy software with clean UI, strong logic, debugging, validation, and performance in mind.
What you can expect:
Clear communication
Clean and organized code
Responsive design
A functional browser-based tool
Simple explanations of how to use it
Revisions based on the selected package
Please message me before ordering so we can confirm the scope, features, and delivery time.
