About Me

Hello! I'm Sajed, a detail-oriented and fast-learning CSE undergraduate from Rangpur, Bangladesh. I have hands-on experience building Kotlin Android applications, integrating REST APIs, and applying data analysis and modeling techniques through a data science internship and industry certifications from Deloitte and DataCamp.

I'm comfortable working independently or in cross-functional teams — following structured workflows, maintaining clear documentation, and delivering under deadlines. My competitive programming background in C++ keeps my problem-solving sharp.

I'm eager to bring strong analytical skills and a quick learning attitude to real-world AI/Data projects in a hybrid, deadline-driven environment.
