Self-Hosted Systems for a Subscription-Free Life
I design and build Django applications and self-hosted tools for creators and small businesses who want control over their digital systems. My approach blends modern Django development with a growing focus on offline-first applications - giving people software they can run and own themselves.
From micro eCommerce sites to personal productivity systems and privacy-focused tools, my work centres on stability, ownership, and pricing that stays accessible - either low-cost subscriptions or one-off purchases.
