Final-year BSc Computer Engineering student at Shahid Beheshti University focused on reinforcement learning, robotics, multi-agent systems, and reasoning in large language models. I co-developed a SEMI-CTDE region-based multi-agent deep RL architecture for adaptive traffic signal control and am extending this line of work in my bachelor thesis using graph neural network–based MARL on urban traffic networks. I also have hands-on experience with modern large language models through the LLM Armenia summer school and applied NLP and vision–language projects. I enjoy tackling difficult problems, learning new things, and exploring fields in depth.
I am currently seeking Master’s and PhD positions aligned with these interests.

Multi-Class Emotion Recognition using DistilBERT
Final project – Introduction to Machine Learning
Multi-Class Emotion Recognition using DistilBERT
Natural Language Processing · Emotion Recognition · Multi-Class Classification

Implemented an end-to-end emotion recognition pipeline: fine-tuned a pre-trained DistilBERT model on a custom emotion dataset, then used its embeddings as input to an MLP classifier with per-label threshold tuning to improve classification performance. The project includes dataset preprocessing, hyper-parameter search, and a simple real-time inference.

Fundamentals of Robotics Course – Projects
Mobile Robotics · Kinematics · Localization · Navigation

Developed a sequence of assignments and a final project for a mobile robotics course, covering kinematics and wheel-velocity control, localization and hallway mapping, local navigation with Bug algorithms, and an indoor mapping and navigation project where a Mavic platform and TurtleBot perform wall-following, door detection, and particle-filter-based localization to reach target doors.

Connect Four AI – minimax and Q-learning agents
Final project – Artificial Intelligence
Connect Four AI using Minimax and Q-Learning
Game AI · Minimax · Alpha-Beta Pruning · Q-Learning

Implemented two AI agents for the Connect Four board game. The first uses a minimax search with alpha–beta pruning and configurable depth to control playing strength; the second is a tabular Q-learning agent trained via large-scale self-play. The project contrasts search-based and reinforcement-learning approaches to decision making in a fully observable game.

Final project – Game Design
Unity 2D Platformer
C# · Unity · 2D Platformer

Built a tiny 2D platformer in Unity with a responsive run/jump controller, simple enemies with health bars, and collectible hearts. The game features multiple themed biomes (forest and snow) with a smooth transition and a clean project structure, making it a reusable template for future sidescroller ideas.
