About Me

Sadia Farzana Jessi

I’m a Software Engineering graduate of SUST, having completed all coursework and my internship, with a strong interest in building scalable, intelligent web applications and in empirical software engineering research. I work primarily with modern JavaScript frameworks, backend systems, and AI-powered features, focusing on clean architecture and real-world usability.

My undergraduate thesis investigated LLM-based pull request reviewer recommendation using frequency-weighted knowledge units, evaluated across four large-scale JavaScript repositories; the manuscript is currently being finalized for submission to the E-Informatica Software Engineering Journal.

I’ve built and deployed full-stack projects using Next.js, Node.js, Go Echo, PostgreSQL, GORM and Prisma, and have hands-on experience integrating Gemini AI, authentication systems, and data-driven features. My work also extends to machine learning and computer vision, including projects with YOLOv8 and AI-based automation.

Beyond development, I actively participate in hackathons and problem solving. I’m also involved in technical communities at SUST, contributing through leadership and collaboration. I’m passionate about continuous learning, building impactful products, and turning complex ideas into practical solutions.
Outside of tech, I enjoy traveling, exploring nature, and discovering different cuisines, experiences that fuel my creativity, adaptability and curiosity.
