I specialize in designing end-to-end ETL pipelines, workflow automation, web scraping, API integrations, and interactive Power BI dashboards that improve operational efficiency and support data-driven decision-making. I have successfully delivered projects involving Python automation, data extraction from dynamic websites, REST API integrations, data cleaning, SQL database development, business intelligence reporting, and cloud-based data processing. My solutions are designed to handle large datasets, automate repetitive tasks, and provide reliable, production-ready results. My technical expertise includes Python, SQL, Apache Airflow, Selenium, Scrapy, BeautifulSoup, Pandas, Power BI, PostgreSQL, MySQL, MongoDB, AWS, REST APIs, ETL pipelines, workflow automation, data engineering, web scraping, data analysis, and business intelligence. I focus on writing clean, scalable, and well-documented code while maintaining clear communication throughout every project. Whether it's building automated data pipelines, extracting structured data from websites, integrating third-party APIs, creating executive dashboards, or automating business processes, I aim to deliver high-quality solutions on time and exceed client expectations. My goal is to help businesses save time, reduce manual work, improve data quality, and make informed decisions through reliable data engineering, analytics, automation, and reporting solutions.
