Building at the seam of software and AI.
welldun is where I build practical, multi-tenant infrastructure — and write up how it actually works. Field notes on the bets, the gotchas, and the things you only learn by shipping and measuring.
What I'm building
projects, written up as series Drafting Table 5 parts

A multi-tenant voice-calling backend — STT + LLM + TTS, bring-your-own-keys, consumable by any third party.
Email Infra soon
A multi-tenant email-sending API — BYO SendGrid/Resend, envelope encryption, a Postgres work queue, signed webhooks.
