Challenge
- Help major US sports leagues safely return players and staff to arenas during the COVID-19 pandemic.

01 — Challenge
When the pandemic hit, professional sports faced a problem no one had planned for: how do you safely bring hundreds of players and staff back to arenas and training facilities? League protocols demanded proof of vaccination, clearance workflows, and up-to-date health status for every person in a team's environment, and none of that could run on spreadsheets.
Two of the largest professional sports leagues in the United States needed dedicated platforms to manage it. The systems had to be simple enough for players to use without training, strict enough to satisfy league health protocols, and ready quickly, because seasons do not wait for software.
03 — The Solution
We engineered health compliance portals tailored to how sports organizations actually operate: around teams, rosters, and league-wide rules.
- Invitation-based onboarding, with account activation via secure email verification on both web and mobile webn- Guided vaccination intake: personal details, vaccination status, vaccine manufacturer, and dose dates captured in a few stepsn- A personal vaccine record with card-based dose tracking, so each person could add doses as they received them
- Team roster views with live vaccination status for every player and staff member: fully vaccinated, partially vaccinated, not vaccinated, or pending clearancen- Fast roster search and filtering by role (players vs staff), built for the daily reality of team operationsn- User management with tiers and roles reflecting league and team hierarchiesn- Support for identifiers connecting each person to the league's wearable contact-tracing devices and testing facility workflows
- Implemented secure, invitation-driven account activation flows, including tokenized email verification suitable for a high-profile user basen- Modeled vaccination status as a derived state machine, so clearance labels updated automatically as doses and league rules changedn- Built roster views and search to stay responsive for full team rosters, applying the same query discipline and frontend performance practices we bring to every projectn- Designed the data model to accommodate league-specific requirements, such as third-party device identifiers and testing facility integration points, without hardcoding either league's rules
Result
Both leagues received working, league-branded compliance platforms during a period when speed mattered as much as correctness. Team staff could see at a glance who was cleared, players could manage their own records in minutes, and health protocols that would otherwise have been enforced through paperwork became a live, searchable system.
The engagement also demonstrated something we value: the engineering practices we developed in regulated clinical research translated directly to a completely different industry with its own urgency and its own rules.
06 — Business Impact
The platform became the operational backbone of the client’s participant engagement: agents could move through scheduled calls efficiently, managers had live visibility into the floor, and study teams received clean, attributed survey data. Phone-based outreach turned from a manual coordination problem into a managed, measurable workflow that ran across multiple studies at once.
