Objective

1. Stop a surge of unwanted form submissions for an agency client.

Front-end & Design

I designed a custom verification modal that triggers right before the final form submission. I reused the site’s existing styling to ensure the UI felt like a native part of the brand.

OTP Verification System‍

Built a serverless security layer using Cloudflare Workers to filter out bot traffic:

1. A Worker intercepts the submission and generates a One-Time Password (OTP).
2. The code is sent to the user via SendGrid API using the client’s existing infrastructure.
3. The Worker validates the input before allowing the form to successfully submit.

The functional prototype was developed in a few hours and fully deployed the following day.
