Context :

BNP Paribas is a French international banking group, I joined their global investing arm BNP Corporate and institutional Banking (BNP CIB), BNP is building their own private internal cloud, each service now is or is about to furnish it’s value in an automated way. I joined the data agility service, as a Tech Lead to help them with their automation by building APIs and workflow around the product and services they fournish to the other teams.

Mission & realisations :

Our service team is based between Paris, London and Madrid, most (70%) are DBAs, the dev team I am responsible for (3 other devs) are in Paris.

Before being completely entrusted with the Tech Lead position,

The biggest technical challenge I had to take, was a complete rewrite of the main legacy software our service is relying on.

Once the rewrite was successful, with the team, we made to stabilise the delivery of our products by building monitoring tools, improving the logs introducing smarter strategy to handle failures of the external systems our

apis interact with.

We're constantly trying to facilitate the work of our support by shortening their feedback loop to customers or adding value to our customer trough features

I'm also responsible, of 4 kubernetes cluster in 3 regions (Europe/middle-east, America, Asia-Pacific)
