Personal Projects Portfolio
I build apps, tools and AI systems on my own, from an autonomous trading system to a privacy-first wellness app, macOS apps and a Japanese learning app.
Featured Project
Velox is my most ambitious project.
A terminal-native autonomous equity trading system on Alpaca. Six strategies feed an 18-stage signal pipeline with ML confidence gating, a unified exit orchestrator, real-time VaR and a tiered circuit breaker, all driven from a single velox command. Paper trading by default.
My Work
Apps, tools and models across macOS, iOS and the web.
A privacy-first wellness companion for university students: on-device stress signals, an adaptive daily check-in and short evidence-based exercises. Started in the KU Leuven KICK Challenge, now being built as a native iOS app.
Your Claude.ai session and weekly usage, right in the macOS menu bar. Built from scratch so you know exactly what it does with your session key.
A small, native macOS browser on WebKit: sidebar and pinned tabs, a memory-conscious tab lifecycle, and sessions built never to lose your tabs. Swift and SwiftUI with no third-party dependencies.
An offline-first Japanese learning app for JLPT N5: FSRS spaced repetition across 720 vocabulary words, 39 grammar points and 83 kanji, with streaks, mock exams and optional cloud sync.
A Go (囲碁) web app with a built-in MCTS AI and 30 tsumego puzzles, each proven solvable by an exhaustive solver. The whole interface is in hiragana and katakana, so it doubles as reading practice.
An automated pipeline that grows a DPO preference dataset: the same model answers each prompt twice, once as a thorough expert (chosen) and once tersely (rejected), so no human annotation is needed.
About
Lumen Studio is my personal projects portfolio. I research, design, and build intelligent systems with a focus on performance, reliability, and real-world impact.
My work spans autonomous trading systems, NLP models, AI assistants, and smart productivity tools. Every project is built with care, from architecture to deployment.
