Projects
A selection of projects showcasing my work in data engineering and software development
Competitor Pricing Tool 🏆
Hackathon Winner 2017Winner of the 2017 Drukwerkdeal Hackathon. Developed an automated competitor price tracking system that eliminated hours of manual work. The tool tracks prices based on fixed configurations, monitors new or removed products from competitors, and sends alert messages to webhooks (Slack integration). Uses custom scraping patterns per competitor with configurable time intervals. Successfully transitioned from hackathon POC to full production system, now used by Marketing and Products teams.
The system stores price data in databases and uses Qlik Sense for visualization. Currently tracking over 20 competitors including Drukwerkdeal, Flyeralarm, Vistaprint, Print24, and many others across multiple regions.
Project CHAPPiE - ML Service Monitoring
Machine Learning 2017Pioneering machine learning project from 2017 - a time when ML was still relatively new in the industry. Developed an intelligent service monitoring system that uses machine learning to detect anomalies in service response times, going beyond traditional hard-coded thresholds.
The system learns from historical data to understand normal response patterns, accounting for factors like time of day, workdays vs. weekends, and seasonal variations. Unlike static alerting systems, CHAPPiE adapts to changing usage patterns and can detect problems that would be missed by hard triggers. This early work in ML for operations monitoring demonstrated forward-thinking in applying data science to infrastructure problems.
Data Mesh Architecture with dbt Mesh
Data EngineeringLeading the transition to Data Mesh architecture using dbt Mesh, enabling decentralized data ownership while maintaining governance. Implementing semantic layer connections and AI-powered Streamlit applications for enhanced data accessibility and insights.
Data Ingestion & Transformation Pipeline
Data EngineeringDesigned and implemented scalable data ingestion pipelines using Fivetran and custom Python scripts, ingesting data from multiple sources into Snowflake. Built comprehensive dbt transformation layers, flattening raw source data into reusable base models for all data teams.
Customer Care Analytics Platform
Data EngineeringBuilt comprehensive analytics platform for Customer Care, integrating data from Genesys CIC, Zendesk, PostNL, Mopinion, Trustpilot, Kiyoh, and Closealert. Transformed data using Alteryx and dbt, creating numerous Looker dashboards for KPIs and business insights.
DTAP Street for Data Engineering
DevOps & InfrastructureDesigned, developed and deployed the complete DTAP (Development, Test, Acceptance, Production) street for data engineering teams. Implemented GitLab repositories with automated linting and testing of merge requests, using dbt Core for pipelines and dbt Cloud for documentation.
E-commerce Backend Systems
Backend DevelopmentDeveloped and maintained various backend systems for e-commerce platform including purchasing, manufacturing, shipping, and quality control modules. Built using PHP, Symfony framework, MySQL, and integrated with AWS services (DynamoDB, SNS, SQS) for scalable operations.
GPS Tracking & Route Optimization System
Software DevelopmentEnhanced and developed GPS tracking and route optimization system integrated within CTIS (Car Technics Information System). Processed real-time location data from GPS trackers, including speed, altitude, and operational metrics. Integrated with warehouse operations for automated inventory management.
