I build the systems that keep records honest.

Consensus is a boring word for something that matters.

Open to backend, platform and open-source engineering work.

I work on the unglamorous half of software: the APIs, schemas, queues and consensus plumbing that decide whether a product can be trusted at scale. Day to day that means TypeScript and Node on the surface, PostgreSQL and Prisma underneath, and Hedera’s consensus service when a record has to outlive the company that wrote it.

Most of my output is open source, and most of it is maintenance rather than launches. I help maintain the Python and Swift ledger SDKs for Hiero — the Linux Foundation project underpinning Hedera and compatible networks — and the conformance runner that holds every Hiero SDK to the same test suite. I also maintain ClyCites, a market intelligence platform for Ugandan farmer cooperatives that started as a university project and did not stop.

I studied Software Engineering at Bugema University and work at Open Elements across Java and TypeScript services. Most of that has been OES, their S3-compatible object storage service — proving it against the workloads a real application throws at object storage: multipart uploads, presigned URLs, versioning and ranged reads, with no fixtures and nothing mocked.
