I take products from a napkin sketch to a robust production environment — and I'm the person you call when the system is slow, the bug only happens on Fridays and nobody remembers why that cron job exists. Pragmatic, results-first, allergic to over-engineering.

🚀 Things I've built

Project What it does
🔔 jcm-gnome-jira-indicator GNOME top-bar counter of the Jira issues that still need you. Highlights what changed, one-click open, one-line install.
🧪 realistic-test-data Synthetic test data in CSV, JSON, SQLite, PDF, PNG & JPEG — foreign keys resolve, totals reconcile to the cent, check digits validate.
⚡ pretty-json-viewer Virtual-scroll JSON viewer: 600k+ lines, ~87 DOM nodes, zero freezes. Vue 3 component or zero-dependency vanilla JS.
🔥 cprofile-and-dashboard Profile Django API endpoints and explore the hot paths in a browser dashboard. Find the bottleneck, not a guess.
🐳 django-full-stack-template docker compose up and you have Django, Celery, Beat, Flower, Redis, PostgreSQL, Mailpit and a DB UI.
📥 django-csvfixtures Plug-and-play Django admin add-on: populate any model from a CSV like a fixture, straight from the admin.
🔐 django-vue-otp-2fa Email OTP two-factor login with Django REST Framework, JWT and a Vue front end.
😷 mask-detector Real-time video stream classifier that detects whether people wear a face mask.

…plus scrapers, Arduino experiments and a Kotlin time tracker I used every single workday — browse everything →

🧭 How I work

  • Root cause over quick fix. A patch that hides the bug is a bug with a delay.
  • Simple beats clever. The best architecture is the one the next developer understands on a Monday morning.
  • Measure, then optimise. Profilers before opinions (yes, I built one).
  • Ship it, then make it better. Production is where products start, not where they end.

🐍 Eating bugs, one commit at a time

☕ Fuel the next tool

If one of my tools, guides or snippets saved you a day of debugging, keep the coffee flowing — it turns directly into more open-source.
