Alexandre
Laurans

Senior Platform Engineer · SRE Tech Lead

I build internal platforms developers actually want to use. 10 years shipping cloud & on-prem infrastructure - Kubernetes, AWS, Azure - currently at Kiln.

Scale

Operated 47 Kubernetes clusters across 22 cloud and on-prem regions.

Ownership

Owned SRE roadmaps with CTOs; led teams of senior engineers.

Breadth

10 years in production across AWS, Azure, GCP, Scaleway, and on-prem - ~50% on-prem at Kiln today.

Developer Experience

Platforms as products - developer self-service from commit to production.

Security

Security by design - workload identity, zero trust at scale, supply-chain hardening, secrets management.

AI Platforms

Shipping AI-assisted tooling and agentic workflows for platform teams at Kiln; drove AI/agentic adoption across engineering at Hublo.

From product spec to production in one commit

The problem

Shipping to production meant routing through the platform team. Every new service was a ticket, a wait, and a handful of inconsistent decisions about networking, observability, and security. That doesn't scale - not the infrastructure, and not the people maintaining it.

The approach

Before committing to a line of infrastructure, I interviewed the stakeholders and the platform's real customers - our developers - to build for an actual need, not an infrastructure trend. That product mindset is the difference between a platform people are forced to use and one they reach for.

What I led - across the stack

Developer paved path

Directed the design of a golden path that takes a service from product spec to production in a single commit. Observability, alerting, and security are part of the path, not an afterthought.

Kubernetes platform

Led a re-architecture of cluster operations around four non-negotiables I refused to trade off against each other: developer autonomy, performance, security, and cost.

AWS network foundation

Drove the rebuild of the networking layer (VPC and IP-addressing design) for scale - and for safe, secured interoperability with private partners.

~3 days → ~45 min

New service: zero to production

4 teams

Shipping autonomously

Zero

Platform tickets in the deploy path

Observability, alerting, and security ship on the paved path by default - reliability built in, not bolted on.
