Live forecast ledger
My contribution
Prediction engine, calibration, and versioned forecast ledger.
Challenge

Football form fluctuates, context matters, and moving between competitions introduces calibration problems that a single signal cannot handle reliably.

Solution

A prediction engine that blends XGBoost, ELO ratings, and market consensus into calibrated forecasts for the Premier League and World Cup. Every forecast is recorded and settled against the result.

Working demo · In development
My contribution
Broadcast analysis pipeline: detection, tracking, and team classification.
Challenge

Broadcast video is unstructured. Manually tagging players and estimating positions takes time away from tactical analysis.

Solution

A pipeline that detects and tracks players and the ball, classifies teams, and renders annotated broadcast footage with trajectories and analysis overlays.

Annotated rugby output

Cropped frame from the Sports Vision rugby demo showing player detections and team labels.

The demo shows detections, persistent track IDs, and team labels. Pitch projection and velocity estimates remain in development; the health warnings in the clip reflect incorrect velocities.

Available on the App Store
My contribution
iOS application, on-device guidance, and agentic development workflow.
Challenge

Trying to change everything at once can lead to burnout and make a sustainable daily rhythm harder to find.

Solution

An iOS app for seasonal focus, small actions, and reflection. On supported devices, Apple's on-device model suggests actions privately; built-in suggestions keep the app usable when Apple Intelligence is unavailable.

Published iOS application

Shipped for iPhone and iPad

The App Store listing includes app screens and release history, with Chester Corin listed as the developer. Cadence data stays on the device, and no account is required.

Agentic Health

Status
In development · No public demo
My contribution
On-premise AI architecture and distributed local inference.
Challenge

Automating personal healthcare workflows while keeping sensitive data away from external AI providers.

Solution

An on-premise AI cluster that distributes inference across local hardware to support private health workflows.

Flo

Status
Prototype · No public demo
My contribution
Raspberry Pi companion and conversational debugging workflow.
Challenge

Making rubber-duck debugging a conversation with a physical companion on the desktop.

Solution

A 3D-printed, Raspberry Pi-powered companion that grew from a weather widget into an LLM-integrated assistant. Flo responds to spoken problem descriptions with questions that help work through the problem.
