The engineering problem
A real-time companion platform combines complex asynchronous state, long-lived sessions, and external services. As the product grew, the frontend needed to support that complexity while improving the experience on mobile.
What I owned
Frontend architecture and system design, from server rendering and data loading to client-side state, background synchronization, analytics, and production monitoring. I also established frontend standards, led code reviews, and mentored engineers.
The work
Optimized media, deferred resources, and tightened the critical rendering path. Alongside the performance work, I built product features and integrated external APIs, working closely with product and design.
Outcomes
- LCP improved from approximately 20 seconds to approximately 3 seconds.
- Initial mobile payload fell from approximately 4.3 MB to approximately 1.7 MB.
- Eliminated major main-thread blocking problems.
