Who is RD Purno?
I'm Rahimanid Dian Purno — a final-semester Computer Science & Technology student from Bangladesh, working at the intersection of AI, human-computer interaction, and intelligent systems.
My work starts with a question: how do we make computers understand humans more naturally? AURA was my first real answer — a gesture control system that replaced the mouse and keyboard entirely using only a webcam and hand tracking. No special hardware. Just code that understands what your hand is doing.
I built JLPT Samurai because I needed it myself. I'm learning Japanese because Japan leads the research I want to pursue: HCI, robotics, and applied AI. I'm not going as a tourist. I'm going to work.
Right now I'm studying ML module by module — not rushing, actually understanding. My industrial attachment targets an ML/AI placement. I direct AI as a research and build partner, not a shortcut. Research-first approach before every project.
“I'm not the finished product. I'm someone in motion.”

Things I've Built.
Each project is an answer to a real question. Not tutorials repackaged.
AURA ⭐
“Control your PC with your hand. No gloves. No sensors. Just a webcam.”
The question was: can a computer understand human gesture as naturally as it understands a mouse click? AURA is that answer. Real-time gesture control using MediaPipe's 21-point landmark model, a custom Gesture FSM, multi-process SharedMemory IPC architecture, and a PyQt6 dashboard with live telemetry. 11 distinct gestures. Zero overlap. Fully offline.
JLPT Samurai ⚔️
“I needed a Japanese learning platform. So I built one.”
The question was: why don't Japanese learning platforms feel like they were built by someone who actually needs to learn Japanese? So I built one myself. Full SRS system, 3D flashcards, time-attack quiz engine, and Firebase cloud sync. I use it every day. That's the best proof it works.
Smart Home 🏠
“Works even when the internet goes down.”
Dual-microcontroller system. Voice control via Alexa and Google Home. But the safety pipeline — fire detection, gas monitoring, emergency door unlock — runs fully offline. No WiFi needed for safety.
UniLib 📚
“AI-assisted. Human-directed.”
A next-gen library management system built with a deliberate AI-assisted workflow — I directed every architectural decision, AI handled implementation. Human judgment directing machine capability.

The Road So Far.
Not a timeline of achievements. A research direction.
The Foundation
NOWFinal semester CST student. Building AURA v4. Studying ML — linear algebra, statistics, NumPy, Pandas — module by module. Japanese every single day.
First Real Test
SOONIndustrial attachment in ML/AI field. Not just coursework. Real problems, real data, real constraints.
The Key
IN PROGRESSJLPT N4 → N3 → N2. Japan's research community operates in Japanese. I intend to operate inside it, not beside it.
The Environment
THE GOALBSc in AI in Japan. Not because it's prestigious. Because Japan's work in HCI, robotics, and applied AI is where I need to be to answer the questions I'm asking.
The Work
WHYPhD in AI. Build systems that understand humans more naturally than they understand themselves. That's the research direction. Everything else is preparation.
Let's Talk.
If you're a recruiter, scholarship committee, research lab, or internship manager — I'm actively looking for the right opportunity. Let's talk about what I can contribute.
