Featured Projects
Sample works and personal projects
Farmsy — Local Farm Discovery SaaS
Live subscription platform for finding local farm shops across the Netherlands and Belgium. ~8,000 listings, five languages, web app plus iOS and Android.
Farmsy is a production subscription SaaS I built and run end-to-end: an interactive map of ~8,000 farm shops across the Netherlands and Belgium, a subscription paywall with free trials, and a full admin platform for managing listings, claims, submissions and support. Payments run across three billing rails — Stripe on web, RevenueCat on iOS and Android — kept in sync by webhooks so a user is never double-charged. Also includes a community feature-voting roadmap, five-language internationalisation, automated trial and win-back email sequences, and EU-compliant analytics. Live on Google Play, with the iOS build in review.
Chlorophyll-a Estimation System

Pamper & Relax Spa
Web-based appointment and spa management system with inventory tracking, transaction monitoring, and convenient booking platform for customers.
Pamper & Relax Spa is a web-based appointment and spa management system designed to support both customers and business operations. The website allows users to browse available spa services and products, schedule appointments by selecting a date, time, and service, and submit payment proof for booking confirmation. On the administrative side, it supports inventory tracking, transaction and sales monitoring, and appointment management. Overall, the system streamlines spa operations while providing customers with a convenient and user-friendly booking and information platform.
Eye Blink-Pattern Detection System
Real-time eye blink detection system using computer vision to monitor patterns and assess cognitive states, fatigue, and eye strain through comprehensive analysis.
A real-time eye blink detection and analysis system using computer vision and machine learning. This system monitors eye blink patterns to assess cognitive states, detect fatigue, and identify potential issues like eye strain or stress through comprehensive JSON logging.
BPO Company Monitoring System
A comprehensive real-time PC monitoring system designed for BPO (Business Process Outsourcing) companies to track and monitor computer performance metrics across multiple workstations.
A comprehensive real-time PC monitoring system designed for BPO (Business Process Outsourcing) companies to track and monitor computer performance metrics across multiple workstations.
