We at Preply do our best to ensure that our website loads quicky as it has huge impact on business. In my talk I will explain:
- why pageload metric is important from business standpoint and how to measure its impact.
- how we evolved with our speed optimization technics starting from very basic ones(caching, orm optimizations) to more advanced(replicas, load-balancing) and the level where we are now(CDN optmization, microservices etc.)
- I will talk about both front-end and backend optimization with focus on the stack we use: AWS, Django/Python, Postgres, Docker.
