Julien Castets, aka niluje / brmzkw, fullstack & infrastructure engineer.
I build the infrastructure
other engineers build on.
What I love
Infrastructure is what gets me up in the morning
I like it best when what I build isn't the end product, but the thing other people build their own product on.
-
Plakar
Building the backup software that keeps everyone else's data, and work, safe.
-
KoyebA cloud platform giving developers containers and serverless compute to build on.
-
Scaleway
Fullstack engineer across REST APIs, networking, deployment and sysadmin.
-
beta.gouv.fr. Tech lead on le.taxi and MesADS, two French govtech products. -
Rentabiliweb. System engineer in telecom, where it all started. -
Freelance. Various missions over the years: development, sysadmin, audits.
The common thread: good infrastructure is invisible. I like building the part nobody notices, so everything on top of it just works.
Range
Comfortable across the whole stack
"Fullstack" for me means more than frontend and backend: it's systems and network too, and everything else it takes to get something into production.
- React & frontend
- REST / API design
- Systems programming
- Network programming
- DevOps & CI/CD
- Linux & sysadmin
- Cloud architecture
- Troubleshooting production
How I work
Scope is a suggestion
I know how to program, and I enjoy it, but writing code has never been the goal for me. The goal is doing whatever the project actually needs. In practice, that has meant:
-
Organizing team building
Planned and ran every team building event at Scaleway.
-
Designing hiring
Specified the recruitment process later used to hire hundreds of engineers at Scaleway.
-
Running the offsite kitchen
Organized the grocery shopping and cooking for Koyeb's team offsites.
-
And much more
I talk to clients, show up at physical events, give conferences, train people, write specs, and generally do whatever needs doing.
Some of that is engineering in its own way: designing a hiring process is really just designing a system for people. Cooking for twenty people at an offsite isn't. Either way, it needed doing, and I'd rather be useful than stay inside a job description.
Let's talk
Available for a few days of consulting
I'm currently full-time at Plakar and not looking for a new role. That said, I'm sometimes available for short, focused consulting engagements: an infrastructure audit, help unblocking a gnarly backend problem, or a fresh senior pair of eyes on your stack, done remotely from Prague, Czech Republic.
