SideQuest — a fullstack job-tracking platform I designed and built during a career sabbatical. It tackles a real pain point: scrolling through endless LinkedIn (and other) job descriptions to see if a role matches your stack.

• The product: A Chrome extension captures job postings from LinkedIn, Indeed, Reed, and CV Library; the app uses AI (OpenAI) to summarise each listing into structured tech stack, skills, pay, and contract details so you can scan quickly.
• The stack: .NET 8 backend (ASP.NET Core, Vertical Slice / CQRS with MediatR, DDD, Transactional Outbox, PostgreSQL, EF Core, JWT + OAuth, SignalR), React 19 SPA (TanStack Router & Query, Radix UI, Tailwind CSS 4, Framer Motion, Storybook), Chrome extension (content scripts + server-side parsing with AngleSharp), and a static marketing site (TanStack Start).
• What I learned: Modern .NET (async, event-driven, DDD, CQRS), AI integration at scale (prompt pipelines, token billing with Stripe), building Chrome extensions and cross-site scraping, and owning the full lifecycle from UX and frontend through backend, payments, and deployment.
