Reaction Training & Hand-Eye Coordination Platform

ReactMotion is a proprietary cognitive performance platform developed by ReactForge. It is built to train and measure reaction time and hand-eye coordination using standard webcam technology connected to a PC or laptop, requiring no specialized hardware.

The platform uses real-time computer vision to capture, analyze, and score a user's physical response to on-screen stimuli. It is designed to serve a broad population: from youth athletes building foundational reaction speed to senior adults maintaining neuromotor sharpness to training elite athletes to maximize cognitive performance.

ReactMotion is not a peripheral device product. It is a software-first platform that turns any device with a webcam into a certified reaction training tool. The goal is to make professional-grade reaction and hand-eye coordination training accessible, measurable, and scalable.

We're looking for talented developer who thrives on innovation to bring a product from prototype to production. You will be the technical lead on ReactMotion, working directly with the ReactForge founder to define architecture, build features, and ship a platform that is ready for institutional adoption.

As Lead Developer, you will be responsible for:

Rebuilding the prototype into production-grade code Integrating with Supabase and the ReactForge data layer Deg the webcam + computer vision pipeline Ensuring performance on consumer grade hardware Build the scoring and analytics engine Establish the technical architecture for scale Design the user-facing training interface Collaborating on product roadmap and feature prioritization

Required Skills: React or Next.js (frontend) JavaScript / TypeScript WebRTC or getUserMedia API for webcam access Canvas API or WebGL for rendering Supabase (auth, database, storage) REST API design and implementation Git and collaborative development workflow

Additional skills that would be an asset: MediaPipe or TensorFlow.js experience Computer vision background Prior work on real-time data capture applications Sports technology, health tech, or EdTech domain experience Experience with AI-assisted development workflows

The Lead Developer will be evaluated against the following milestones:

Webcam capture pipeline functional, basic reaction drill running end-to-end Core drill library complete (5 drill types), scoring engine live Athlete dashboard, session history, and export to PDF operational Coach dashboard, drill builder, and Supabase integration complete ReactView integration live, API layer documented and tested Platform commercially deployable for first institutional pilot

ReactMotion already works with a working prototype. This role is not about building from zero. It is about taking a functioning prototype and turning it into a live platform.

To be considered, a concise reply must be received for all 3 interview questions.
