Platform Engineer / Infrastructure Architect and Team Lead with 15+ years of experience delivering scalable cloud and self-hosted platforms. I build internal platforms, AI infrastructure, and high-performance systems - and I lead the teams that run them (up to 8 engineers: hiring, mentoring, architecture ownership).
- 🧠 AI infra at scale - GPU orchestration on Kubernetes (MIG profiles, multi-GPU scheduling, H100-class nodes), LLM stacks with vLLM · Ollama · Ray/KubeRay, models up to 671B parameters in multi-GPU environments
- ☸️ Kubernetes everywhere - EKS, kubeadm, Kubespray, hybrid cloud + bare-metal, custom Calico CNI traffic routing, GitOps with automated self-healing
- 🛠️ Platform services in Go & Python, Terraform, GitHub Actions with self-hosted runners, Karpenter autoscaling, APISIX
- 🎮 Off-hours: real-time 3D on the web (Svelte + Threlte + WebXR), multiplayer game servers on Agones, Godot games, and electronics - my GitHub history starts with quadcopters and Arduino PID loops
🚀 Now building - theprototype.app
Collaborative peer-to-peer 3D prototyping in the browser. Open source, no backend. Svelte 5 + Threlte, P2P sync, zip-installable community modules, content packs, and a PR-driven community gallery.
