Principal Platform & Security Engineer · Barcelona, Spain

Adam Lahbib

Multi-cloud Kubernetes platforms, GitOps delivery, eBPF and zero-trust security, and self-hosted AI systems, built and run at production scale.

I take ownership of the platform layer everything else depends on: cluster architecture, infrastructure as code, production access, telemetry and incident response. Teams bring me in when the work has to be done right the first time and keep running afterwards.

Outcomes, not job titles

Zero-downtime cluster replacements. Re-architected a production platform for multi-cluster EKS with weighted-DNS cross-cluster routing and continuous lifecycle upgrades.
50+ serverless functions to Kubernetes-native GitOps. Migrated AWS Lambda functions and event-source mappings from the Serverless Framework using AWS Controllers for Kubernetes.
Terraform to Pulumi, zero downtime. Rebuilt network layers, platform add-ons and security stacks during an IaC modernisation.
15-minute, 2 TB restores. Authored the immutable-backup RFC required for SOC 2 at a global HR SaaS platform.
Global XDR rollout and SIEM migration. Integrated AI SOC level-1 responders for high-severity threats.
Zero-trust production access. A customised temporary-elevated-access workflow on AWS SSM, enforced for every production touch.
An offender-monitoring platform built end to end. ~56% of commits across a polyglot backend (Python/FastAPI, Go, Rust), GCP/GKE infrastructure and mobile agents; Pub/Sub with transactional inbox/outbox; per-device DNS-over-TLS monitoring; in-memory threat-list pipeline for real-time alerting.
Self-hosted multimodal LLMs on a single GPU. Fine-tuned and quantised models powering an automated AI image-evaluation pipeline.

06 — Selected technical work

Low-level and open work

pingkiller

xounce
Edge API security platform (Envoy ext_proc or eBPF agents) that rebuilds requests and responses from schema so attacker-crafted input never lands and sensitive data never leaves.
Kli8nt backend
Go backend orchestrating cloud-native deployment pipelines: GitHub APIs, GKE, Redis, Google Crane for daemonless image operations.
4n6nk8s research blog
Co-founded technical blog on vulnerability research, DFIR and Kubernetes exploitation; hosted DFIR workshops for university students.
