Built real-time update system and automated WhatsApp notifications via third-party API integration. Implemented optimistic concurrency control to handle scheduling conflicts and prevent double-bookings. Architected backend with PostgreSQL database and business logic for user, booking, and operations management. Improved operational efficiency and user experience through automation and integrated information flow.

A full-stack, single-page web app for managing your job search pipeline — with real-time stats, bulk actions, undo/redo history, multi-currency salary display, and secure authentication. Free to self-host. I built this app out of my own experiences in job hunting, acknowledging that such tool would be useful to keep track of the roles I applied for and having data like so available meant I could analyse what I could improve in from that.
