👋 Hi there, I'm Hamza Haddougui

🚀 About Me

Welcome to my GitHub! I’m a passionate developer with a strong background in web technologies, Java and geographic information systems. I’m currently expanding my expertise into AI, modern front-end frameworks, and advanced mapping solutions.

🧑‍💻 Projects & Contributions

  • Angular/Angular: Exploring and contributing to the Angular framework. See my StackBlitz for live demos and experiments with the latest Angular features.

  • Batch Payment History Processor: A robust public repository designed to automate the processing of daily payment operations.

    • Workflow: The application ingests a flat file of CSV type, validates and processes the records through a specialized batch application layer, and finally stores the resulting items into a PostgreSQL relational database.

    • Goal: To streamline financial data workflows and ensure data integrity between raw inputs and relational storage.

  • Devographics/locale-ar-EG: Contributed to the Arabic localization of Devographics surveys, ensuring cultural and linguistic accuracy for the regional developer community.

  • Truecaller:

    • Contributed by adding names to identify both individual and business callers in the mobile application.

    • Improved data quality by suggesting more accurate names when Caller ID information was inaccurate or irrelevant.

    • Participated in UX surveys and the rewards program to optimize the user experience.

  • Samsung Global Goals: Donated to support initiatives ending poverty, reducing inequality, and fighting climate change.

🗺️ Geographic Systems & Mapbox Experience

I have hands-on experience designing and developing geographic systems and interactive maps. My journey includes:

  • Mapbox Studio and Mapbox GL JS (JavaScript-based, cross-platform: Angular/React/etc.).
  • Working with GeoJSON data for dynamic, interactive mapping.
  • Building server-side interactions with non-relational databases to serve geospatial data.
  • Designing and visualizing custom geographical cards for presentation and analytics.

I'm currently looking for help and collaboration in:

  • Designing advanced geographic systems.
  • Creating visually engaging, interactive geographical maps.

📈 Professional Impact & Metrics

  • Real-time Monitoring: Delivered a dashboard landing page tailored to 7 business profiles, providing real-time visualization of JIRA issues filtered by status and role.

  • Microservices Optimization: Developed a server-side microservice capable of filtering and calculating 1,000+ issue identifiers in under 50ms for direct front-end display.

  • Legacy Migration: Spearheaded the migration of a massive global stylesheet (+5,000 lines) into a modernized Angular v13 architecture.

  • High-Performance Data Processing: Optimized batch processing to handle 1 million payment records in 20 minutes and scaled to 10 million records in just 30 minutes.

  • Telecommunications Process Optimization: Increased contract verification speed by 60%, reducing overall processing time from one week to just 3 working days.

  • Geospatial Visualization: Streamlined access to trusted real estate listings by implementing a 4-layer geographic map interface powered by the Mapbox framework.

🌱 Currently Learning

  • Deep-diving into AI tools, services, frameworks, and concepts via the Microsoft Learn platform.
  • Enhancing my knowledge of the latest Angular features and best practices.
