QUEST LOG

Experience

  1. MAIN QUEST · IN PROGRESS

    Software Engineer @ TakeOffLabs

    Oct 2024 – Present
    • Served as the sole full-stack developer for 2 years on an AI-first B2B CRM/ERP, owning Rails, React, TypeScript and PostgreSQL end-to-end and working directly with clients.
    • Built a sandboxed AI agent able to perform any action available to the current user; generated its callable TypeScript/JavaScript API from YARD-documented Rails services.
    • Implemented customizable role-based access control (RBAC) and interactive approval for state-changing actions across background processes and foreground WebSockets using IPC.
    • Improved AI-agent performance by replacing web API communication between the agent worker and main server with IPC and pipes, eliminating the need for networking.
    • Optimized AI latency and inference cost through prompt/context design, code-based tool execution, caching and regular cross-model benchmarks.
    • Built multi-account AI email automation for Gmail, Outlook and IMAP/SMTP, plus real-time private, group and announcement messaging.

  2. QUEST COMPLETE

    Software Engineering Intern @ Accenture Industry X

    Jun 2024 – Aug 2024
    • Built a demonstration manufacturing execution and operations management (MES/MOM) application with Angular and ASP.NET Core, modelling industrial manufacturing workflows.

  3. QUEST COMPLETE

    Lead Developer @ ACard (KMDSZ)

    Nov 2022 – Jun 2023
    • Implemented every major feature of a Flutter and Directus student-card app used by hundreds of students at its peak.
    • Delivered most core features in a three-developer team, covering registration and access to public transport, events and partner discounts.

  • Drives locally installed Claude Code, Codex and similar tools, so users bring their existing subscriptions instead of another API bill.
  • Electron, React and TypeScript desktop app for Windows and macOS (Apple Silicon and Intel).
  • Every pull request runs typechecking, unit and component tests, a production build and an Electron end-to-end suite.
  • Every green push to main ships versioned installers to GitHub Releases, picked up by the app’s built-in auto-updater.

Windows Orphan Cleaner

Ownership-aware cleanup for Windows 10/11 that links leftover application data to the software that created it.

  • Explains every conclusion and never deletes directly: cleanup goes to a restorable quarantine, only after review.
  • One Rust engine, two front-ends: a Tauri desktop app and a browser UI backed by a loopback-only local agent, sharing a single command dispatcher.
  • Live scan progress over Server-Sent Events, with snapshot reconciliation after reconnects and dropped events.
  • Its folder analyzer also runs entirely in the browser through the File System Access API.
