DESCRIPTION:Modern astronomical web platforms increasingly integrate intera
 ctive data exploration\, authenticated data access\, and online analysis s
 ervices. As these capabilities expand\, usability\, accessibility\, and se
 curity become fundamental design requirements. We present the Cherenkov Te
 lescope Array Observatory (CTAO) Science Data Challenge (SDC) Portal as a 
 case study of how these complementary requirements can be addressed within
  a modern\, open-source astronomical web platform.\n\nThe portal couples a
  React front end with a FastAPI microservice architecture and exposes obse
 rvation metadata through International Virtual Observatory Alliance (IVOA)
  standards\, including TAP/ADQL and ObsCore. These community standards mak
 e Cherenkov data accessible to astronomers beyond the high-energy communit
 y while promoting FAIR access to astronomical data through open interfaces
  and an open-source implementation.\n\nUsability is supported through sour
 ce-name resolution\, coordinate and time conversions\, interactive visuali
 sations\, reusable data baskets\, and submission of selected observations 
 as preview jobs. Accessibility is improved through colour-blind-safe visua
 lisations and CTAO usability guidelines.\n\nThe platform follows a service
 -oriented architecture separating authentication\, application logic\, and
  data download. Authentication and authorization are handled through OpenI
 D Connect. A dedicated download service resolves logical file names to dis
 tributed storage endpoints and performs OAuth 2.0 Token Exchange for direc
 t file downloads. Persistent application data are associated only with pse
 udonymous user identifiers\, while personal profile information remains co
 nfined to temporary session state. The platform is deployed using containe
 rs\, Helm\, and Kubernetes\, supported by continuous integration\, automat
 ed code quality checks\, and Grafana observability. Together\, these engin
 eering practices improve software quality and maintainability\, while ongo
 ing cybersecurity hardening prepares the platform for future CTAO operatio
 ns.
