LEAGUE MANAGEMENT AND LIVE SCORING PLATFORM
Built for a professional sports league
A league management platform replaced legacy cricket tooling with offline-first scoring, sub-second sync and broadcast-grade overlays. Scorers keep working when field connectivity drops, and public scorecards update as play happens.

Challenges
Legacy cricket platforms were slow, administration-heavy and disconnected from broadcast. Scorers worked on unreliable field connections, overlays lagged behind play, and league staff had limited control over scheduling and historical records.
Unreliable connectivity
Field cellular connections dropped mid-match, risking lost scoring data.
Slow presentation
Overlays lagged behind the scorer, making live broadcasts feel delayed and amateur.
Administrative burden
Scheduling, historical records and league setup were manual and error-prone.
Constraints
Offline-first scoring with reliable local recovery.
Sub-second sync between scorer actions and broadcast overlays.
Compatibility with OBS browser sources used by streaming partners.
Historical player and league data must survive migration.
Administrative controls for fixtures, records and league setup.
Reference
Architecture
Scoring client
A fast scoring interface maintains local state on the device, so a dropped connection does not interrupt or lose the match record.
Local state · Offline cache
Sync engine
Scoring events reconcile with the server when connectivity returns, and live events propagate to public surfaces with minimal latency.
WebSockets · Event sync
League administration
Fixtures, teams, players and historical records are managed in a structured admin surface with migration tooling for legacy data.
Admin UI · CSV migration
Broadcast layer
A dynamically generated browser-source URL renders the live scoreboard for OBS, so partners can present consistent graphics.
OBS browser source · Overlay rendering
Data
Flow
- 1
The scorer records a ball or event on the device.
- 2
The scoring client updates local state immediately.
- 3
The event syncs to the server when connectivity allows.
- 4
Public scorecards update from the synced event stream.
- 5
The overlay URL renders the current score for OBS.
- 6
Historical records are written for league statistics.
Delivery
MVP wedge
Offline-first scoring, scheduling and public scorecards.
Broadcast
OBS overlay URLs and live presentation.
Administration
Fixtures, records and historical migration.
Ecosystem
Expanded commercial and league features.
Hard
Problems
Offline recovery
Problem: A dropped connection mid-over could leave the match state inconsistent.
Resolution: The client keeps authoritative local state during the match and reconciles with the server on reconnect, preserving event order.
Overlay latency
Problem: Broadcast graphics lagged behind the scorer, which viewers notice immediately.
Resolution: Scoring events are pushed to the overlay surface through a low-latency channel instead of polling.
Historical migration
Problem: Legacy platforms held player career records in inconsistent formats.
Resolution: A CSV-assisted migration pipeline normalizes records before import so Day 1 statistics remain continuous.
Results
Resilient scoring
Matches continue when field connectivity drops, and data recovers without re-entry.
Broadcast-ready
Overlays update in step with scoring through a standard OBS browser source.
Controlled administration
Fixtures, records and league setup are managed from one platform.

Lessons
Offline-first is a state-ownership decision, not a cache setting.
Broadcast latency is a product feature; viewers forgive errors faster than they forgive lag.
Migrate historical data before launch, not after — continuity is the trust signal.

FAQ
Frequently asked questions
The scoring client keeps authoritative local state during the match. If connectivity drops, scoring continues on the device, and events reconcile with the server when the connection returns.
Scoring events are pushed through a low-latency channel to the overlay surface, so graphics update in step with the scorer rather than polling on a delay.
Yes. A CSV-assisted migration pipeline normalizes legacy player and league records before import, so historical statistics remain continuous from Day 1.
Yes. A dynamically generated browser-source URL renders the live scoreboard inside OBS, so streaming partners can use consistent graphics.
