## About

I'm a builder at heart. After 20 years in software I keep coming back to the same thing: taking an idea from zero to a working product with my own hands — the storage engine, the UI, the go-to-market, all of it.

Right now that means [LogzAI](https://logzai.com), an AI-native log observability platform I built solo on a hand-built Delta Lake storage engine (one of 3 winners at the inVest accelerator Demo Day), and [Zenve3d](https://zenve3d.com), my newest venture. Before these I co-founded Zapant, a trading platform that executed 300K+ live transactions, bootstrapped from AntSignals — a trading-journal SaaS I grew to ~€2K/month with zero ad spend.

I like hard technical problems (I once wrote an OS from scratch), small teams, and products that make money without permission.

## Projects

### LLMBrain — Founder · Cross-project brain for coding agents

- URL: https://llmbrain.dev
- Status: building (active)
- **Agent-first remote MCP server** — coding agents start every session blind and siloed per repo; LLMBrain is the one hosted place they read and write context about *all* of your projects.
- **Canonical docs per project**, maintained by the agent itself — architecture, data model, product, status — with a **docs_health** signal that tells the agent what has gone stale.
- **Milestones and issues** as the roadmap — the agent picks up work, marks what is in progress, and records where it left off for the next session.
- **Tool descriptions are the UX** — the primary user is an LLM, so every response is shaped for a context window instead of a screen.
- One-line install — `curl | bash` bootstraps an npm CLI that wires MCP config, session hooks, and a conventions skill into Claude Code and Codex.
- Tech: Python, FastAPI, FastMCP, PostgreSQL, React, Next.js, MCP

### Zenve3D — Founder · Professional parametric CAD for makers

- URL: https://zenve3d.com
- Status: beta (active)
- **Full parametric CAD** — editable sketches, constraints, dimensions, features, and a complete modeling history: change an early dimension and the rest of the model updates with it.
- Every field takes **expressions** — a parameter's name works anywhere a number does.
- One modern **C++ geometry engine**, native on macOS and iPad — touch and Pencil on the tablet, full desktop workflows on the Mac.
- Built-in **MCP server** — AI assistants plug straight into the modeler: sketch, model, and inspect parts through natural language.
- Professional CAD workflows **without enterprise complexity or enterprise pricing** — built for makers: 3D-printed parts, CNC components, robotics, enclosures, prototypes.
- Tech: C++, Swift, Geometry kernel, MCP, macOS, iPad

### LogzAI — Founder · AI-native log observability platform

- URL: https://logzai.com
- Status: active
- **AI-native log analysis** — chat with your logs, get any log explained, and let automatic pattern and anomaly detection surface problems before you go looking.
- **Purpose-built log agent** — custom tool suite and prompt architecture that plans multi-step investigations across millions of logs and answers with evidence.
- Custom storage engine on the **Delta Lake open format**, over S3 or local disk — **6M+ logs** for a single organization, full-dataset SQL queries in seconds.
- **Full SQL** over everything through DuckDB — query builder with attribute filters, saved and shared queries, and smart alerts when something goes wrong.
- Open format end-to-end: no bespoke index, **no lock-in** — any tool that reads Delta Lake can read your logs.
- Tech: TypeScript, Node.js, Python, DuckDB, Delta Lake, Docker, Kubernetes

### Zapant — Co-Founder & CEO · Automated trading platform

- URL: https://zapant.com
- Status: 300K+ tx
- **Automated trading bots** for stocks and crypto — pick a public bot with strict risk-management protocols, connect your broker, and go live in minutes.
- [**Zplang**](https://zaplang.com), an open-source Clojure-inspired trading language with built-in assets and indicators — a strategy is a few lines of code, backtested and executed from the terminal with [**ZapCLI**](https://zapcli.com).
- **Custom strategies** — write your own bots in JavaScript or Zplang and run them live on the platform.
- **300,000+ live transactions** executed against real brokers, with real money on the line.
- Tech: TypeScript, React, Node.js, Zplang

### AntSignals — Solo founder · Trading-journal SaaS

- URL: https://antsignals.com
- Status: €2K MRR (active)
- **A trading journal that finds your edge** — import trades straight from your broker and let the reports show which setups make money and which quietly bleed it.
- **Data-driven feedback** on everything: peak-performance hours, position sizing, pattern and mistake detection — across stocks, indices, forex, options, and crypto.
- **AI insights, a trade simulator**, and multiple portfolios with customizable reports and rich data visualization.
- Independently reviewed — [Bullish Bears](https://bullishbears.com/antsignals-review/) calls its **data-driven feedback** the platform's biggest strength.
- Tech: TypeScript, Vue, Node.js

### vue3-charts — SVG charting library for Vue 3

- URL: https://github.com/ghalex/vue3-charts
- Status: 150+ stars
- **#1 search result for “vue3 charts”** — SVG charting for Vue 3, intuitive and extensible.
- **Charts are templates** — Grid, Bar, Line, and Area compose as declarative layers.
- Docs and live examples at [vue3charts.org](https://vue3charts.org).
- Built on top of **D3** — D3's math, Vue's reactivity.
- Tech: Vue 3, SVG, TypeScript

### PhiOS — Operating system from scratch

- URL: https://github.com/ghalex/phios
- Status: hobby
- **Boots on bare metal** — assembly bootloader into a C++ kernel, shipped as a bootable x86 image.
- **C++ with no OS underneath** — hand-rolled runtime support, VGA text driver, port-I/O layer, custom linker script.
- Runs in **QEMU** straight from the repo — x64 and ARM ports sketched in the tree.
- Tech: Assembly, C++, x86
