Hey, I'm Laurentiu

Software engineer, founder of Bitheap, AI builder. Based in Zürich, Switzerland.

I'm a full-stack developer with 15+ years across software development, security and QA automation. I spent the better part of a decade building and breaking systems for financial institutions, and these days most of my energy goes into AI products, systematic trading research and options analytics.

Since 2022 I've been running Bitheap, where I build and ship the ideas for small and medium organizations.

What I'm working on

• GPT Trading Agent — an LLM-driven agent that researches and executes trades.
• GreekFlow — options analytics: Greeks, flow and volatility surfaces.
• Select Supply — clothes, cars, games and other objects that I love.
• Dave — a one-stop shop for everything AI-related.
• QuantiQ — real-time market, historical and financial data.

Teaching

Somewhere along the way I ended up teaching more than 100,000 students — 75k+ on Udemy, plus courses on Pluralsight. I've written four books on Amazon, I write on Medium and the Pluralsight blog, and I put videos on YouTube.

This is where I keep the longer-form notes. Start with the articles, or say hello.
