Ouassil D.

I help businesses build robust backend systems and automate workflows with Python. From scraping websites and creating ETL pipelines, to developing APIs and deploying ML models, I deliver reliable, scalable solutions that turn raw data into actionable systems. With 4+ years of experience in telecom and enterprise environments, I’ve built end-to-end backend solutions handling large-scale datasets, automation, and machine learning applications. What I Do Best: ✔ Web Scraping & Data Extraction – Python, Selenium, Scrapy, BeautifulSoup, Playwright, and APIs for extracting structured data from complex websites. ✔ Data Engineering & ETL – Collecting, cleaning, and transforming data from APIs, databases, and files (CSV, JSON, Parquet) into production-ready pipelines. ✔ Workflow Automation – Python scripting and Apache Airflow for reliable orchestration and scheduling. ✔ Machine Learning – Developing practical predictive and classification models using Scikit-learn and XGBoost. ✔ Backend Systems & APIs – Building and deploying FastAPI/Django APIs and automation bots for seamless integration into workflows. Tech Stack: Python, FastAPI, Django/DRF, PySpark, Pandas, SQL (PostgreSQL, MySQL, Teradata, Hive), Selenium, Scrapy, Apache Airflow, Scikit-learn, XGBoost, Docker, Linux. I take projects from raw data to fully automated, production-ready backend systems, scalable, maintainable, and ready to integrate with your business processes.
