Nexus
A distributed scheduling engine built for zero-latency conflict detection across all major calendar providers.
Nexus is a Calendly-inspired <strong>high-performance scheduling platform</strong> engineered from the ground up for speed, using <strong>Go's native goroutine concurrency model</strong> to handle heavy calendar synchronisation logic at scale.
Real-time calendar conflict detection across multiple providers (Google, Outlook, Apple) is computationally expensive and brutally slow in traditional interpreted languages, causing <strong>latency spikes</strong> that degrade the booking UX at scale.
Architected a <strong>multi-threaded Go backend</strong> utilising <strong>Redis caching</strong> and <strong>Google Calendar + Microsoft Graph webhooks</strong> for near-instant availability updates, with optimistic UI ensuring the experience feels instantaneous.
