I build infrastructure that handles billions of webhook events and serves property records to millions of users.
About
I'm Success Kingsley, a backend and systems engineer. I build infrastructure that needs to work reliably at scale.
Over the past five years, I've helped companies like Svix deliver billions of webhook events and Landeed bring transparency to India's property records. Most of my work is in distributed systems, API design, and data infrastructure.
I write mostly in Rust these days, though I'm comfortable across the stack. I've worked on secure sandboxes for untrusted code, string search algorithms, and crash-proof logging for payment systems. I care about getting things right and writing code that's clear enough for the next person.
Right now, I'm working independently with early-stage teams. I also tinker with side projects like NaijaScript, a programming language that lets you code in Nigerian Pidgin English.
If you're working on something hard and want someone who sweats the details, let's talk.
