## Talk Description

Modern frontend teams often rely on powerful UI frameworks to move fast, but over time, those tools can quietly become bottlenecks. What once accelerated development begins to add weight, slow down performance, and make customisation more complex than it should be. In a world where performance budgets are tight and user expectations are high, these slowdowns aren’t just inconvenient — they’re real risks.



In this talk, the speaker shares a real-world story of how their team decided to move away from MUI and rebuild their component library using Clean CSS and CSS Modules. The goal was clear: reclaim speed, flexibility, and full control over the UI. From analyzing performance bottlenecks to managing the migration in production, this session covers the key decisions, trade-offs, and outcomes that reshaped how the team builds frontend experiences.
