I build the systems I operate.

Most IT managers buy their tools. I write the ones my department runs on, and answer for their uptime on the same report.

  1. Internal platform

    TI Hub

    IT service desk with an SLA engine, inventory, maintenance, custody letters and monthly KPI reporting, plus a friction-free portal for any worker to file a report.

  2. Internal system

    Attendance

    Time clock for home-office staff with no application server: every business rule lives in PostgreSQL, punches are append-only and the client holds no write privilege on any table.

  3. Internal platform

    Maintenance portal

    Work orders with assignment, log, per-machine history and statistics, scoped across five sites including customer-site service centres at BRP, Hella and Faurecia.

  4. E-commerce

    B2B Marketplace

    Recycled-plastics commerce with direct purchase and RFQ. Selling to invited customers since 1 September 2026, multi-vendor in production since 15 September.

  5. Corporate website

    PIMSA Web

    Public website of an engineering-plastics recycler, with the panel that runs it: Marketing works the leads and the stock catalogue, HR runs a job board that takes CVs, and neither area sees the other's data.

  6. Open source

    MeetScribe

    Real-time meeting transcription and minutes, fully local on Windows: dual-track WASAPI capture, CPU Whisper and on-device diarisation.

  7. Browser extension

    Password Vault

    Local password manager for Chrome and Edge. Envelope encryption with AES-256-GCM and scrypt derivation at twice the OWASP minimum; keys live only in the service worker.

  8. Board game companion

    Woodland Setup

    A companion for balanced Root games, with faction selection, turn-based drafts, Reach validation and local game history.

  9. Tabletop RPG companion

    D&D Companion

    A D&D 2024 tabletop console with a character sheet, attack rolls, rules-aware spellcasting, resource tracking and a campaign journal.
