Nammu21 — fintech AI site with custom Lottie interactivity
Nammu21 — fintech AI site with custom Lottie interactivity

The Project

Full production for Nammu21, a FinTech AI startup that needed a custom site urgently for their Round II funding push. Not a "tweak some animations" gig — animation, front-end, back-end, analytics, ads integration, build pipeline, deployment. Webflow was a delivery platform; everything else was hand-coded.

The Challenge

Two parts. First, the design called for page-by-page navigation with no scrolling — every page transition is its own interaction, and Webflow's built-in nav couldn't do what the design required. Second, the site needed three separate versions for different aspect ratios (not just breakpoints), and every Lottie animation had to be tuned per aspect-ratio version. That's not a CSS media query situation. Each version got its own animation work and its own per-version logic.

What I Built

Custom no-scroll page-by-page navigation written from scratch in JavaScript. Webflow's built-in nav was bypassed entirely.
Three aspect-ratio-specific site versions with per-version Lottie tuning, driven by custom mutation/intersection observers that pick which version loads.
Custom Lottie interactivity layer with hand-written trigger logic — beyond standard auto-play.
Node.js bundle pipeline with version-stamped JS bundles for cache-busting on every deployment.
Google Analytics + Google Ads tracking wired into the page-by-page navigation events so funnel analytics actually worked.
Whole site deployed and maintained end-to-end through the Round II push.

Technical Stack

After Effects, Lottie/Bodymovin, Webflow, JavaScript, Node.js, Google Analytics, Google Ads. The Webflow site itself was just the delivery surface — the navigation engine, animation logic, observers, build pipeline, and analytics layer were all custom code.

The Result

A FinTech site that didn't look or behave like a Webflow template, ready in time for the funding round. Live at nammu21.com. One of the largest projects in my portfolio by scope and a clear example of Webflow being used purely as a delivery platform on top of custom-built logic.
