Centene Corporation

Application Software Engineer June 2022 - Current

Improved multi-aspect search system featuring simultaneous search queries across various data sets, with optimized mongo indexing to avoid collection scan, provides easy and quick search for user.

Enabled PWA functionality by registering service worker using Workbox. With landing page being cached at initial user login and member data precached in Indexed DB, ensured continuing access to essential app features when offline.

Caching only business required apps upon login, avoiding caching unused apps thus slowing down the overall system efficiency and memory usage. Allowing users to perform tasks with modularized, offline-accessible data, ensuring individual child app functionality without network connectivity.

Designed a background sync queue to enable record manipulation offline with service worker to track sync progress and queue changes made offline. Once the internet connection is restored, queued data updates are processed sequentially to ensure consistent synchronization.

Implemented a time-based cache validation mechanism by checking the last synced timestamp stored in IndexedDB, ensuring outdated data is cleared to prevent cache overflow. This optimization improved overall app performance and mitigated potential memory leaks.

Using RBAC for SSO to ensure each account has access to pages and data appropriate to their responsibilities

Centralized configuration allows the main platform to control versioning and deployment of all child applications, restricting changes to authorized maintainers only. Ensuring consistent behavior across the system and simplifies access, integration, and maintenance.

Designed a GUI that sends requests to application endpoints providing health status and displays the relevant information in the UI. This was achieved by leveraging REST APIs and subscribing to observables to reactively update app details.
