// about me

Engineering ideas
into reality.

I'm a CSE undergraduate at East West University, Dhaka — obsessed with building things that actually solve problems, from AI-powered retrieval systems to last-mile delivery platforms.

My work sits where frontend engineering meets machine learning. I enjoy system architecture as much as a clean UI — both feel like puzzle solving to me.

As President of EWU Robotics Club, I've led events that brought together 2000+ students from across Bangladesh. Technology is more meaningful when it connects people.

// experience & leadership

Where I've shown up.

2024 — Present
President
EWU Robotics Club (EWURC)
Took over one of EWU's most active technical clubs and scaled it into a national platform. Beyond running the club's day-to-day operations, the defining achievement was directing EWU National RoboFest 2026 — Bangladesh's premier student robotics festival — from concept to execution.
"Running NRF26 taught me that the real skill isn't technical — it's getting 30 different people to care about the same goal."

Graphics Designer
Executive Committee — EWU Robotics Club
Built the visual language for club events and campaigns before stepping into leadership. Every banner, social post, and event identity passed through me. That's where I learned how design shapes perception before anyone reads a single word.
"Good design is what makes people stop scrolling."

// research & publications

What I'm thinking about.

Research Interests

Drawn to problems at the intersection of AI systems, optimization, and real-world logistics. Interested in how retrieval-augmented generation and graph-based optimization apply to delivery, legal systems, and recommendation engines.

AI in LogisticsRAG SystemsRecommendation EnginesGraph AlgorithmsIntelligent Automation

Ongoing Work

Developing Dropify as a research-grade delivery optimization system — exploring edge-based interpolation models with Shapely and OSM node snapping. Also conducting applied data mining research across clustering, text mining, and association rule learning.

Publications in progress — coming soon.
