You will get a custom web tool, calculator, or interactive widget built and tested

Project details
I build custom web tools, calculators, and interactive widgets that are fast, clean, and work perfectly on desktop and mobile. Whether you need a pricing or ROI calculator, a lead-capture form, a unit converter, a quiz, or an embeddable widget for your site, I turn your idea into a working tool with tidy, lightweight code (React / HTML / JavaScript) that you can trust.
I use modern AI tools to move faster on drafts and boilerplate, then personally review, test, and stand behind every deliverable. You get speed and a human who owns the result. You'll always know the exact scope, timeline, and price up front, and I test everything on desktop and mobile before delivery.
Message me your goal and I'll tell you honestly if I'm the right fit.
