You will get a custom interactive calculator for your Webflow website.
Project details
Transform your Webflow site into a high-converting lead generation machine with a custom, high-performance interactive calculator. I specialize in developing bespoke tools using vanilla JavaScript, ensuring your logic is accurate, fast-loading, and completely free of bulky third-party plugins that can slow down your site. Whether you require a simple price estimator, a complex mortgage calculator, or a multi-step ROI tool with conditional logic, I deliver pixel-perfect solutions that match your brand’s UI exactly. My development process focuses on mathematical precision and clean code, ensuring seamless performance across all mobile devices and browsers. Beyond simple calculations, I can integrate your tool with external databases, generate downloadable PDF summaries, or sync lead data directly to your CRM via Zapier or Make. By providing immediate, personalized value to your visitors, you’ll increase engagement and build trust with your audience. I bridge the gap between complex math and intuitive web design, creating powerful interactive experiences that are easy for you to manage and impossible for your competitors to ignore. Let's turn your formulas into a professional product.

Website design
Very skilled. Great design sense. Super quick. She went above and beyond to incorporate my feedback, which was often quite detailed and must have been annoying at times. I am very pleased with the final product. Thanks, Tatiana!

Logic Analysis & Formula Validation
I’ll start by reviewing your formulas and variables. I'll double-check the logic in a Google Sheet or Excel to ensure the mathematical output is 100% accurate before I start writing any code.
UI Construction in Webflow
I will build the frontend structure (inputs, sliders, dropdowns, and result blocks) directly in Webflow. I’ll follow your design files or existing style guide to ensure the calculator looks like a native part of your website.
