Built production SaaS with 1k+ users

I led the development of a modern SaaS platform designed for high-throughput data processing. Key technical challenges solved: - Implemented a serverless architecture that scales automatically based on load. - Optimized database queries reducing average response time from 1.2s to 120ms. - Built a custom real-time notification engine using WebSockets and Redis. The project currently serves over 1,200 active users and remains a core part of the organizations infrastructure.
