Services
Twenty years of building and running software and hardware infrastructure, available for your projects.
I design and build web platforms, deploy smart homes that respect your privacy, and help teams run reliable systems.
Based in Prague, working remote or on-site.
Web development
Websites & web applications
Web development | Sparrow CMS · Django · Wagtail
Complete websites and web applications, from first sketch to production. Most of my web work is built on Sparrow CMS, a Django/Wagtail platform with presentation, education and e-commerce editions.
It powers this site, geekedu.eu, gameedu.eu and mathbook.cz. Your project gets a proven production platform, not a one-off codebase.
E-commerce & integrations
Web development | Sparrow commerce · invoicing · imports
Product catalogs, subscriptions and invoicing with PDF generation, search, and integrations that pull structured content from any external source.
Operations included
Web development | Kubernetes · monitoring · backups
Every site ships running on a managed Kubernetes platform with TLS, backups, monitoring and automated deployments. You get a working product, not a code handover.
Smart home deployment
Design & deployment
Smart home | Home Assistant · ESPHome · MQTT
Smart home automation designed around your household: lighting, heating, shading, security and presence. Everything runs locally on your own hardware, with no cloud accounts required.
Custom sensors & devices
Smart home | custom firmware · 3D-printed enclosures
Purpose-built ESPHome devices for measurements off-the-shelf products do not cover: energy, water, air quality, garden and workshop telemetry.
Household observability
Smart home | Grafana · Prometheus
Dashboards and alerting for your home: energy consumption, temperatures and device health, on the same telemetry stack I run for production systems.
IT consultancy
Observability platforms
Consulting | Prometheus · Grafana · Loki · OpenTelemetry
Design and operation of self-managed monitoring platforms: metrics, logs and traces, dashboards as code, alerting strategy and SLOs.
Kubernetes & GitOps
Consulting | ArgoCD · Terraform · Helm
Cluster architecture, GitOps delivery, CI/CD pipelines and infrastructure as code, in the cloud or on-premise.
AI-assisted operations
Consulting | LLM agents · automation
Language-model agents wired into monitoring, deployments and routine operations. I run my own platforms this way and can set it up for yours.
Training & mentoring
Consulting | workshops · reviews
Team workshops on GitOps, Backstage, SaltStack, Prometheus and Grafana, plus architecture reviews and mentoring. See Trainings for the current catalog.
