Senior Software Engineer@Lotus Chess· Berlin (hybrid)

Less latency. More wonder.

I'm Samy — senior software engineer at Lotus Chess in Berlin. I build APIs, cloud infrastructure and data pipelines that don't break a sweat, and 3D toys that exist purely because they're cool. This page weighs less than a JPEG.

Nutshell

ML · NLP

Summarizes multiple news articles into one. Each article runs through a seq2seq model — Bi-LSTM encoder, attention, LSTM decoder — and the abstractive summaries are fused with LexRank into a single extractive summary.

stack: Python, Flask, Next.js, React

This site

WebGL · Web Audio

A raymarched neural core rendered as ASCII, synthesized UI sounds, and a statusline that measures the page while you use it. Zero runtime deps beyond React.

stack: Next.js, React, raw WebGL2

Let's build something cool.

Backend or data problem that needs taming? An AI tooling idea? A 3D experiment that needs a co-conspirator? My inbox is open.
