Purpose, approach, and visual samples.

ANDROID · COMPUTER VISION · EXPERIMENTAL MVP

Motion Coach

Motion Coach is an experimental Android app intended to help users practise squats with visual and spoken feedback. It turns the front-camera pose into a responsive 2.5D avatar and counts repetitions on the device.

THE ENGINEERING DECISION

Rendering and repetition counting share a stabilized pose. Predicted landmarks keep the avatar continuous, while only fresh, high-confidence observations can advance the counter.

THE TRADEOFF

On-device inference keeps camera frames local. Single-camera depth and occlusion remain limitations; this is an experimental prototype, not a validated fitness product.

02 / GEOALARM · MOBILE APPLICATION

Your destination.
Your reminder.

GeoAlarm is designed to alert you as you approach a chosen destination, so you can spend less of the journey checking the map.

Search for a place, choose a route, and follow the journey’s progress. Background location tracking powers the arrival alarm, while saved Home, Work, and favourite destinations make repeat trips easier.

C#.NET MAUIAndroid location services

Intended useDestination reminders for everyday journeys and commutes.

03 / WIFITRACKER · COMPUTER VISION PROTOTYPE

A phone camera.
A traffic sensor.

WiFiTracker turns an Android phone into a vehicle-tracking camera and connects it to a Windows viewer over the local network.

The phone detects moving vehicles, follows them across frames, and selects snapshots for inspection. The desktop receiver displays those captures. The project also explores plate recognition and capture-quality improvements.

C# / .NET 10ONNX RuntimeAndroid + WPF

Intended useLocal vehicle monitoring and capture review, with detection handled on the phone.

Prototype: difficult lighting, overlapping vehicles, and plate recognition still need validation.

04 / PARCELTRACKINGDEMO · INDUSTRIAL VISION

From conveyor footage
to operational insight.

ParcelTrackingDemo is intended to help operators see what passes along a conveyor: detect parcels, follow each one, count it at a trigger zone, and capture a reviewable snapshot.

The interface brings together the live camera view, track IDs, counted status, and parcel snapshots. Open-versus-sealed classification supports condition checks; more precise sizing and automated handling are development directions.

.NET 10ONNX RuntimeOpenCVYOLOX

Intended useConveyor monitoring, throughput review, and visual evidence for operational exceptions.

Demonstration project: physical sizing requires camera calibration and validation on representative footage.

05 / WAREHOUSEWEB · PLATFORM ENGINEERING

Warehouse operations,
built to run anywhere.

WarehouseWeb is an ASP.NET Core MVC control and administration platform for warehouse environments. It brings connectivity monitoring, service supervision, restart scheduling, event-log search, configuration, localization, and user administration into one operational interface.

The engineering work spans a Windows desktop mode and a portable Linux container mode. The Kubernetes branch adds a repeatable app-and-database cluster setup with health probes, persistent SQL Server storage, secrets, and service discovery.

Engineering focusCross-platform runtime configuration, resilient database startup, background hosted services, Windows service integration, and production-oriented observability.
