Data Extraction Specialist Developer (Web Scraping) at Aina Marchel

In May 2018, I held the position of Developer at Aina Marchel, specializing in Web Scraping. This experience allowed me to acquire fundamental and practical skills in automating data collection, a key asset for analysis and Business Intelligence projects.

My responsibilities included:

Extraction Robot Development: Designing and implementing scripts to automatically navigate websites and extract structured and unstructured data.

Data Processing and Structuring: Ensuring that data collected through scraping was properly cleaned, transformed, and formatted for direct use in databases or analysis tools (like Power BI).

This experience is crucial as it demonstrates my ability to manage the beginning of the data lifecycle, from automated collection to structuring, which is essential for any project requiring a reliable supply of external data.

From 2023 to 2025, I served as a Trainer and Business Intelligence (BI) Consultant at Madagascar Data Camp. This hybrid role allowed me to leverage my dual technical and pedagogical expertise for data analysis and digital transformation.

I was primarily responsible for:

Business Intelligence Consulting: Designing and implementing complete decision-making infrastructures. This involved data modeling, using Power BI, and mastering the DAX language to ensure the accuracy and performance of dashboards.

Specialized Technical Training: I trained professionals and students in the advanced use of Excel and Power BI. My web development expertise also allowed me to supervise projects involving Python and SQL.

This experience was essential for honing my client communication and BI project management skills, and for transforming raw data into concrete growth levers for businesses. I am capable of overseeing the integration of analysis solutions from end to end, from data source to final visualization.

Perfect, here is the description of your experience at GSI University, focusing on programming technologies and development fields.

Teacher and Technical Supervisor at GSI University

From 2019 to 2025, I worked as a Teacher at GSI University, specializing in fundamental and advanced courses in programming and emerging technologies. This role was crucial for deepening my mastery of object-oriented languages and Full-Stack frameworks.

My responsibilities and the courses taught covered the following areas:

Basic and Advanced Programming: I taught PYTHON, C#, and C++. This expertise ensures a solid understanding of Object-Oriented Programming (OOP) and algorithmic logic, essential for robust development solutions.

Web and Software Technologies: I taught students to master modern frameworks such as ASP.NET (C#) and Django (Python). These skills are directly applicable to creating complex web applications and business tools.
