Portfolio
Production IoT systems I designed, built, and deployed for clients in Vietnam, Denmark, and Germany.
SaaS / Cloud Hosting / Platform Engineering
A multi-tenant SaaS platform that hosts managed Node-RED, InfluxDB, and Grafana instances. Users spin up an isolated, ready-to-use instance in minutes — with automated backups, one-click upgrades, and per-plan resources — backed by a bilingual storefront.
Solar Monitoring / Industrial IoT / Energy Management
An edge-deployed monitoring platform that centralizes solar production, grid import/export, load consumption, and electrical parameters for an industrial rooftop solar plant.
Energy IoT / Education / Operations Management
An IoT solution monitoring electricity, heat, and water at Idrætshøjskolen Bosei in Denmark — connecting multiple device types and protocols into one centralized platform for clearer consumption visibility and early anomaly detection.
Smart Building / HVAC / Energy Monitoring
A custom end-to-end monitoring solution for heat pump performance, floor-level energy analysis, and historical reporting.
Smart Building / Heating
A fail-safe, 3-layer smart heating system for 40 apartments: Shelly edge control keeps running offline, Node-RED orchestrates MQTT data per apartment, and Datacake provides centralized operations with timer-based energy saving.
