In-Play Sports

When I joined the project, the platform faced several critical issues:

• -Extremely slow page load times, with some pages taking 30-40 seconds
• -Legacy infrastructure limiting scale
• -Undiscovered security vulnerabilities
• -Missing source code for critical services
• -Poorly optimized database queries

The first major task was improving performance across the platform. By analyzing database queries, application logic, and infrastructure configuration, I reduced load times from 40 seconds to near-instant response times for most features.

The root bottleneck turned out to be a production database server that had been running on a single CPU core for more than 10 years. Identifying and fixing that constraint dramatically improved scalability because the system could finally use the hardware it already had.

One of the platform's most important services was a video processing server responsible for uploads, playlists, and telestration rendering. The original source code was missing, so only compiled binaries remained.

I reverse-engineered the service behavior by tracing application and API interactions, then rebuilt the processing server from scratch.

The new system included:

• -RabbitMQ job queues for reliable task handling
• -Prioritized processing tasks
• -Automatic resource management and disk monitoring
• -Automatic service recovery

The platform contained several vulnerabilities that had gone unnoticed for years. In my first six months I performed manual security audits, identified 10+ vulnerabilities, secured hundreds of API endpoints, and added stronger validation around sensitive team data.

I also introduced structural improvements to the development workflow, including cleaner deployment cycles, better source control practices, and automated cleanup tasks.
