Hi There! I'm Tomer Klein
I build and self-host the tools I want to use — Docker containers, Home Assistant integrations and security tooling at MSD Animal Health Technology Labs. Most of it is open source, and all of it runs in production somewhere.

Docker & Containers
Packaging tools and services as clean, self-hosted containers that just run.
IoT & Home Automation
Home Assistant integrations, MQTT, ESP/Arduino and LoRa devices that talk to each other.
Security & DevOps
Zero Trust, firewalls, SIEM/DLP and hardened pipelines — security built in, not bolted on.
Web APIs
FastAPI and .NET services with clean contracts, docs and sensible defaults.
Infrastructure
Nginx, Traefik, Cloudflare, RabbitMQ and databases wired up to stay quietly reliable.
Open Source
Dozens of maintained repositories — tools other people actually run and contribute to.
The tools I reach for, day to day.
Years of building and shipping across backend, containers, IoT and security — here's where I'm strongest.
Discover, learn and replay Broadlink RF/IR commands from a clean web UI, shipped as a container.
Send WhatsApp notifications through the GreenAPI cloud over one simple HTTP endpoint.
A small Flask service that pulls text out of images and PDFs with OCR.
Spot known faces in WhatsApp group photos with DeepFace and alert the right people instantly.
Train and test DeepStack AI models from the browser, no command line required.
A Telegram bot in a container for running and watching your Docker hosts.
