eforus-overseer — AI research, useful tools, and a little curiosity.

LinkedIn   /   X   /   Explore the repositories

Hey, I'm Efi ! 🖖

I'm an AI researcher and data engineer. I like turning interesting ideas into working experiments: training agents, investigating how language models fail, building security tools, and making things you can actually interact with.

I've been working with machine learning since before everything became “cool AI stuff.” The curiosity stuck. Give me a new method or tool and I'll probably build a proof of concept with it.

My recurring interests: language models · reinforcement learning · cybersecurity · data visualization

A few things I've built

Photo Studio's dark workspace displaying a cheerful brown Labrador puppy Photo Studio
A photography playground with 24 desktop effects, foreground segmentation, and an interactive browser demo.

Try the demo ↗ · Source
Python · OpenCV · CustomTkinter · Canvas
Propwash drone simulator flying over the Grand Canyon's satellite terrain PROP//WASH
FPV flight over real satellite terrain. Quaternion flight physics, race gates, and a whole lot of altitude.

JavaScript · Three.js · Terrain data
Iron Tide submarine on patrol in a three-dimensional ocean Iron Tide
A Silent Hunter–inspired submarine game. Hunt convoys, line up torpedoes, and evade destroyers in the browser.

Tools I reach for

Models & data   Python · PyTorch · scikit-learn · pandas · NumPy · OpenCV
Experiments & interfaces   Gymnasium · Matplotlib · Plotly · JavaScript · TypeScript · Three.js
Automation & infrastructure   Playwright · Docker · Git · AWS

A little history: from 2018 to now

My original Photo Editor GUI was written entirely by hand in 2018, before today's AI coding assistants. It's preserved as a legacy project.

Photo Studio revisits that idea with an AI-assisted development workflow, a redesigned interface, more effects, and segmentation. Same curiosity, new tools. Also, a much cuter Labrador.

Research it. Build it. See what happens.
