AWS RDS database management for cloud-hosted workloads.
IoT device integration over MQTT and CoAP — telemetry, status and control.
PICO device configuration and cloud data transmission.
Release support on Linux and Windows/IIS environments.

Mobile development & release

React Native and Flutter alongside earlier hybrid Android/iOS work.
REST/mobile API development and backend integration for mobile clients.
Firebase push-notification integration for Android and iOS.
Payment gateway, order tracking and notification workflows.
Delivered apps to Google Play and Apple App Store.

Data analysis & visualisation

Power and energy consumption analysis with chart-based visualisation.
Operational data dashboards and reporting-oriented features.
Environmental metrics: temperature, humidity, CO, CO₂ and PM levels.
Excel/spreadsheet-based data processing and automation.
