~4,000 real matches

1958 to 2022

fully client-side

Context

Built for United Hacks V7. Runs entirely client-side: no backend beyond one optional LLM route, no database, no accounts.

PitchSide

Event data says who passed from where to where, but never where all 22 players stood at each instant.

The hard part

The work is making that sparse record continuous without ever contradicting it.

What it took

Stitched the ball path from real waypoints, hashing each player's id into a persona.
Normalized each match into uniform-grid typed arrays so a seek is one O(1) sample.
Drove mixers, gait, and audio by match time, so pause freezes mid-stride for free.

Outcome

Won 1st place at United Hacks V7 with a browser match player spanning Pelé's 1958 final to Messi's 2022, carrying five camera modes, an auto-cutting director, and per-decade film stocks.
