Experience

Frontend Engineer @ Bricsys 24/7 (Hexagon) (Sep 2023 - Mar 2026)

  • Built real-time projection of 3D annotations into 2D space for browser-based BIM viewer using React and CSS transforms across shared monorepo functionality.
  • Helped convert Vue 2 to React as part of a migration using Module Federation, working on converting apps and components within the team lead's architecture.
  • Added form validation to the internal Bricsys component library using TanStack Form for use by other teams.
  • Performed daily tasks including feature design, Azure releases, cross-team ideation, documentation, performance measuring, and i18n.

Projects

Pure-Paste

macOS menu-bar app that strips tracking parameters from copied URLs using merged rules from uBlock Origin and ClearURLs. Fully local and private.

Audio Bonanza

Chrome extension for per-tab audio control (speed, reverb, bass) focused on YouTube, with optional Flask SSE backend for LAN-wide remote triggering.

DoubleDash Editor

Chrome DevTools sidebar with fuzzy-search and live edit CSS vars with better workflow than native browser tooling.

Podcast Tooling

Local pipeline using WhisperX and Ollama to transcribe audio, generate summaries, and output ready-to-post social clips.

Timesheet Automation

Headless background process and CLI that pulls Git commits and PR data to auto-fill R&D entries into the internal timesheets app.

Ideaditor

Lightweight Markdown knowledge base bundled with Tauri and Bun for faster ideation, compatible with Obsidian.
