Burning the last GIT commit into your telemetry/log

I enjoy knowing exactly what happens in the systems that I am actively working and that I need to maintain.

Google Analytic with React and Redux

I had to integrate Google Analytic in one of our website at Netflix. It’s been a while I had to use Google Analytic and the last time was simply copy-pasting the code snippet provided by Google when creating the Analytic “provider” account.

I recently have a side project that I am dogfooding at Netflix. It is a library that handles HTTP request by acting as a proxy to cache requests. The goal is to avoid redundant parallel call and to avoid requesting data that is still valid while being as simple as possible. It has few configurations, […]

TypeScript and React – Continuous Integration for Pull Request from 3 minutes to 1 minute
