Behindthe click.
I build software,
inside and out.
The interface, the services it calls, and the infrastructure that keeps it running. Products at Seaionl. Projects of my own. A few things I’m still figuring out.

Things I’ve built, independently and at Seaionl.

InfrastructureStill tinkering.
Open source, loose ends, and ideas worth trying.
Task Executor
Distributed task execution with database-enforced exclusivity, expiring leases, and bounded concurrency. Built to recover when a worker disappears.
GoOpen source
Garbage
A small command-line tool that moves files to the trash, restores them, and empties the bin when you're ready.
RustOpen source
ColumnarDb
An embedded, append-only columnar store for read-heavy analytical workloads. An ongoing experiment in how data gets stored and read.
GoEarly work in progress
A little
context.
I like being close to the whole thing.
A screen is only part of a product. There's also the request that takes too long, the deployment that needs a safer path, and the certificate that has to renew on time.
My work spans frontend, backend, and infrastructure. At Seaionl, that includes React, Django, and Go, alongside PKI systems, Docker hardening, and supply chain security. In my own projects, it means seeing an idea through to something people can use.

TypeScript / React / Next.js
