# Adam Lahbib — Principal Platform & Security Engineer Adam Lahbib is a principal platform and security engineer based in Barcelona who designs and runs multi-cloud Kubernetes platforms, GitOps delivery, eBPF and zero-trust security, and self-hosted AI systems. He works in-house and as an independent principal engineer. - **Location:** Barcelona, Spain - **Availability:** Open to conversations about platform, security and AI engineering work. Email adam@adamlahbib.com. ## Experience - Lead infrastructure security engineer at a global HR SaaS platform: multi-cloud security architecture across AWS and Azure, endpoint protection, compliance. - Principal engineer for a sovereign government monitoring platform serving criminal-justice systems across the Five Eyes nations. - Platform engineer for an airline-operations SaaS: 50+ microservices on AWS EKS with ArgoCD, Istio and Karpenter. - Tech lead and cloud architect for a UK public-sector procurement-compliance SaaS on GKE. - Co-founder of xounce, an edge API security platform that rebuilds every request and response from schema. - PhD candidate in agentic security (SERCOM Lab, University of Carthage). ## Core capabilities - **Cloud native & orchestration:** Kubernetes at scale (EKS, GKE, k3s), multi-cluster and zero-downtime cluster replacement, Istio and Linkerd, Karpenter, Helm. CKA and CKS certified. - **Infrastructure as code & GitOps:** Terraform, Pulumi (C#/.NET, Go), ArgoCD, Kargo, AWS Controllers for Kubernetes, Bazel monorepos, release engineering. - **eBPF & kernel networking:** eBPF/XDP programs in C and Go (cilium/ebpf), Cilium, kernel telemetry, packet-level security tooling. - **Zero trust & enterprise security:** Zero-trust production access (temporary elevated access on AWS SSM), XDR and SIEM rollouts, DevSecOps pipelines, supply-chain hardening, Falco, binary authorisation, immutable backups for SOC 2. - **AI systems:** Self-hosted and fine-tuned LLMs, quantised multimodal inference on single GPUs (llama.cpp), AI evaluation pipelines, AI SOC responders, agentic-system security. - **Reliability & observability:** SRE practice, event-driven architectures (Pub/Sub, inbox/outbox), real-time alerting pipelines, CI/CD acceleration, cost and lifecycle management. ## Track record - Re-architected a production platform for multi-cluster EKS, enabling zero-downtime cluster replacements via weighted-DNS cross-cluster routing and continuous lifecycle upgrades. - Migrated 50+ AWS Lambda functions and event-source mappings from the Serverless Framework to Kubernetes-native GitOps with AWS Controllers for Kubernetes. - Drove an IaC modernisation from Terraform to Pulumi, rebuilding network layers, platform add-ons and security stacks with zero downtime. - Authored an immutable-backup RFC delivering 15-minute, 2 TB restores required for SOC 2. - Led a global XDR rollout, a SIEM migration, and the integration of AI SOC level-1 responders for high-severity threats at a global HR SaaS platform. - Enforced zero-trust production access through a customised temporary-elevated-access workflow on AWS SSM. - Built an enterprise offender-monitoring platform end to end: ~56% of commits across a polyglot backend (Python/FastAPI, Go, Rust), GCP/GKE infrastructure and mobile agents; event-driven Pub/Sub with transactional inbox/outbox; per-device DNS-over-TLS monitoring; in-memory threat-list pipeline for real-time alerting. - Self-hosted and fine-tuned quantised multimodal LLMs on single GPUs to power an automated AI image-evaluation pipeline. - Migrated a public-sector SaaS to multi-cluster GitOps (ArgoCD) under zero-trust, binary authorisation and Falco; productised the internal DevSecOps stack into a multi-tenant AI security SaaS. - Achieved a 150% CI/CD speed-up by architecting auto-scaling GitLab runners and centralised pipeline templates; instituted security and quality gates reporting into SonarQube. - Designed a hybrid multi-cloud Kubernetes platform with Pulumi and Karmada, automated with Kubebuilder; eBPF/Cilium integration for 15% more efficient packet processing and 40% faster security audits. ## Selected technical work - **pingkiller** — Low-level eBPF/XDP network utility in C and Go (cilium/ebpf, LLVM IR) that drops ICMP at the driver interface and exposes real-time kernel metrics to userspace. (https://github.com/adamlahbib/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. (https://xounce.com) - **Kli8nt backend** — Go backend orchestrating cloud-native deployment pipelines: GitHub APIs, GKE, Redis, Google Crane for daemonless image operations. (https://github.com/kli8nt/backend) - **4n6nk8s research blog** — Co-founded technical blog on vulnerability research, DFIR and Kubernetes exploitation; hosted DFIR workshops for university students.
