About
I'm Oluwatimileyin Adewumi — Tony — a software engineer in Lagos. I care about the point where engineering discipline meets experience: products that are fast, tested, and a pleasure to use.
My work runs the stack end-to-end: architecture, databases, payments, messaging, CI/CD, and the design systems that hold a product together. Most of it ships on Next.js, Supabase or Postgres, and Payload — with Paystack, Stripe, and the WhatsApp Cloud API doing the commercial heavy lifting.
The thread through everything: build for the channel people actually use, prove claims in production, and keep the craft visible in the details.
What I'm doing
Founder, Nafara
Building a WhatsApp-first healthcare marketplace connecting Lagos patients with MRTB-verified physiotherapists. 535+ tests and counting.
Adewumi Studio
My engineering practice. Commerce platforms, EMRs, marketplaces — shipped end-to-end for clients across retail, health, and fashion.
Engineering roles & partnerships
I work with product teams as an engineer and with founders as a technical partner — architecture, AI integration, and getting v1 out the door.
