Over deze dienst
Automatische vertaling
Heb je een Flutter app nodig die communiceert met BLE apparaten, IoT sensoren, wearables of slimme hardware? Je bent op de juiste plek.
Ik ben een Flutter Team Lead met meer dan 5 jaar ervaring en 15+ gepubliceerde apps. Ik specialiseer me in BLE communicatie en IoT mobiele oplossingen, een gebied waar veel Flutter ontwikkelaars geen echte productie-ervaring in hebben.
WAT IK bouw
BLE apps scannen, verbinden, lezen/schrijven, meldingen en apparaatbeheer
IoT dashboards real-time sensor monitoring, grafieken en waarschuwingen
Wearable companion apps fitness trackers, gezondheidsapparaten, slimme banden
Hardware controlepanelen beheren en bedienen apparaten vanaf mobiele apps
Cloud-verbonden systemen Firebase, Firestore, MQTT, pushmeldingen
Cross-platform apps één codebasis voor Android en iOS
WAAROM MET MIJ WERKEN
Ik heb echte hardware-verbonden apps uitgebracht naar zowel de App Store als de Play Store. Ik begrijp packet parsing, verbindingsstabiliteit, beperkingen bij achtergrond scannen, firmware communicatie en productieklare BLE architectuur, niet alleen demo projecten.
