GeoStrap — RFID Asset Tracking SaaS
Designing and building an end-to-end IoT SaaS platform for logistics companies — RFID strap tracking via ESP32 + HZ540 hardware, FastAPI ingest and API services, React/Vite frontend, and a full Kubernetes deployment on Proxmox. Multi-tenant, append-only event streams, and a complete observability stack. This is the primary portfolio piece: real product, real architecture decisions.
# what's built
FastAPI ingest + read services · PostgreSQL 16 · Redis · React/Vite frontend · ESP32 firmware (WiFi, NTP, ring-buffer offline queue) · Proxmox K8s architecture designed (Traefik, Longhorn, MetalLB)

AWS 3-Tier Architecture — Terraform

Open to the right role.

I'm looking for DevOps, SRE, or Cloud Engineer roles — ideally somewhere that values a solid IT and support background and wants someone serious about growing into the craft properly.

I'm not pitching myself as senior. I bring 10+ years of IT, real running infrastructure, and a structured learning plan I'm executing against. If that sounds like a fit, I'd like to hear from you.
