Building AI Systems from the Inside Out

I'm a Computer Engineering student who genuinely enjoys understanding how intelligent systems work. I mainly work with Python and have a strong interest in Natural Language Processing, Information Retrieval, and search systems. I also have hands-on experience with Elasticsearch and search concepts such as indexing, retrieval, and relevance. Whenever possible, I like building things from scratch. Working without ready-made libraries can take longer, but it helps me understand what is happening behind the code and gives me more freedom to experiment with different ideas. Recently, I've been spending more time learning PyTorch and exploring how machine learning can connect with the systems I already enjoy building. The part of AI I find most interesting is where research, experimentation, and real software come together.

Core Expertise

I learn best by building things from scratch. If I don't understand how something works, I usually open a notebook and try to rebuild it myself. That's why I enjoy working on search engines, tokenizers, and NLP systems. Getting the final result matters, but I also want to understand what happens underneath.

Aria Haman Mehr Parse

2021 - Present

I started at Aria Haman Mehr Parse as an intern and gradually moved into an engineering role. Over the past four years, I've worked with experienced AI engineers and contributed to AI systems developed for production environments.

One of my main contributions has been to the RGNN project, where I helped develop the tokenizer used in its NLP pipeline. This work gave me practical insight into how research ideas are developed into reliable software for real-world use.

Search-Engine-From-Scratch

A lightweight Information Retrieval system built from scratch in pure Python. I avoided external NLP libraries so I could understand each part of the search pipeline, from tokenization and indexing to TF-IDF, cosine similarity, ranking, and autocomplete.

Learning Together

Learning Together

Learning alongside someone who shares the same curiosity.

I've never enjoyed learning entirely on my own. One of the best parts of this journey has been having one of my closest friends beside me. We spend a lot of time discussing ideas and solving problems together, especially when a concept does not make sense the first time.

Recently, we've been exploring graph learning together. Looking back, I think learning side by side has helped both of us become more effective learners.

Where Retrieval Meets Graphs

The direction I’m exploring at the moment.

A large part of my current learning focuses on RAG systems and graph-based approaches. I’m still exploring both areas, building the foundations step by step and trying to understand how they work in practice.

What interests me most is the connection between retrieval and structured knowledge. I want to understand how a system can find useful information, recognize relationships between pieces of data, and use that context to produce better answers. Graphs make this especially interesting because they offer another way to represent information beyond plain text.

This is still a work in progress for me, which is why I wanted to include it here. RAG and graph systems are the areas I’m actively experimenting with, and I’m interested to see how far I can take them as I learn more.

Growth Without Borders

New places, different perspectives, and more room to grow.

I’ve always been curious about how much I can grow when I step outside what feels familiar.

Living in a new country, especially in an environment shaped by modern technology and new ideas, would give me a chance to challenge myself and adapt to a different way of life. I want to experience places where innovation is part of everyday work, learn how people approach technology and problem-solving, and develop new ways of thinking and working.

For me, moving abroad is a chance to grow through a new experience, become more flexible, and see how far I can push myself when I’m surrounded by unfamiliar challenges and possibilities.

Beyond the Screen

The little things that help me stay creative.

Research and programming take up a large part of my life, but I also find that creativity grows away from the screen. These are a few things that help me recharge and return with a fresh perspective.

Guitar & Music

Music has always been part of my life. I enjoy playing guitar, discovering new songs, and sometimes getting lost in the rhythm. Dancing comes naturally with it and is another way I enjoy music.

Running & TRX

Training helps me slow down and clear my mind. I've noticed that some of my favorite ideas come after a workout, away from my laptop.

A Small Habit

Whenever I'm stuck on a problem, I usually step away for a while. A walk, a workout, or a conversation often helps me find an answer that was not clear at my desk.
