About Me

I’m Syed Rafsan Ahmed, a Computer Science & Engineering student and aspiring Data Analyst & Data Engineer passionate about transforming raw data into meaningful insights and practical solutions. I work with Python, SQL, MySQL, Excel, Power BI, Java, C/C++, and data visualization, with hands-on experience in data cleaning, analysis, dashboards, and machine learning projects.

Alongside my technical journey, I have professional experience in virtual assistance, cold calling, lead generation, appointment setting, data entry, web scraping, CRM management, email/SMS marketing, and client support. I’ve worked with real-estate and insurance businesses and developed strong communication, research, and problem-solving skills.

I’m currently building my portfolio through real-world projects, internships, freelance work, and continuous learning. My goal is to combine data, technology, and business understanding to build solutions that create measurable value.
