I build and improve production-ready web, mobile and SaaS products with a strong focus on clean UI, reliable backend logic and fast delivery. I work with React, TypeScript, Node.js, Express, Flutter, Dart, PostgreSQL, Python, Java, HTML, CSS and WordPress. I deliver fixed-scope features, integrations, bug fixes, responsive interfaces, APIs, dashboards and automation. My work includes Cora.family, LiveView.fun, StromLogic and an IoT traceability system created during Covid-19 using ESP devices, MQTT and Mosquitto. You receive tested code, clear communication and a concise handoff.
