MACHINE LEARNING & ROBOTICS · CWRU

I study and build
machine learning systems.

I'm Fotih, a BS/MS student at Case Western Reserve University. I'm a machine learning research assistant for Prof. Shuai Xu, I built a language model from scratch, and I write computer vision code for the CWRUbotix robotics team.

FEATURED PROJECT2026

Story MoE

A mixture-of-experts language model I built from scratch.

I wrote and trained a decoder-only transformer in PyTorch with sparse top-2 expert routing, rotary position embeddings, and KV-cached text generation. I also wrote tests to check causal attention, routing gradients, and that cached and uncached generation match.

ONGOING RESEARCH

Neural Network Pruning

I'm studying how to prune neural networks so they get smaller without giving up much predictive performance.

Research background

CWRUBOTIX · MATEROV

Robot vision and control

I build real-time computer vision pipelines with ROS and FLIR cameras. I've also written Python nodes for simulated robot control and set up camera streaming on a Raspberry Pi Zero 2 W.

DATA & DECISION TOOLS

Neighborhood Navigator

A terminal program that filters and ranks homes by what you care about, with graphs for comparing them.

Visualization

Project details

I wanted an easier way to compare the properties in a housing dataset. The program reads each home's attributes, applies the filters you choose, ranks the matches with a weighted score, and shows the results in the terminal along with graphs.

INTERACTIVE APPLICATIONS

Virtual Pet Simulator

A pet game where your choices change how it plays. It has a shop with its own money system and an inventory that the game keeps track of.

02 / ABOUT ME

I like knowing
how things work.

I'm pursuing a BS in Computer Science and an MS in Machine Learning and Artificial Intelligence at Case Western Reserve University, with minors in Business Management and Mathematics. My expected graduation is May 2028.

My work spans ML research with Prof. Shuai Xu, robotics software with CWRUbotix, and teaching introductory AI. I'm interested in how model design affects both predictive performance and the practical cost of running a system.

I like to see a project through, from the first version of the code to testing it and checking whether the results hold up.

Where I've worked

SEP 2025 TO PRESENT

AI / Machine Learning Research Assistant

Case Western Reserve University · Prof. Shuai Xu

I read papers on deep learning and mixture-of-experts models to find open questions. I help design experiments that measure model performance and architecture trade-offs, and I talk through model design and next experiments with faculty and graduate students.

JAN 2025 TO PRESENT

Robotics Software Team Member

CWRUbotix · MATEROV

I wrote ROS nodes in Python to control a simulated robot during the team's training bootcamp. I set up a Raspberry Pi Zero 2 W to stream video for a USB photosphere imaging system, and I build real-time object detection pipelines with ROS and FLIR cameras.

AUG 2026 TO PRESENT

Teaching Assistant · Introduction to AI

Case Western Reserve University · CSDS 330

I hold office hours and recitations for a 48-student course and grade assignments and exams for 15 of those students. I also help students debug their programming assignments and review their code for search, machine learning, and probabilistic reasoning.
