About

Backend developer working in Java. I build APIs, design databases, and put together distributed systems. Lately focused on secret management and keeping applications stateless.

Projects

Vassago PoC

GitHub ↗

Proof-of-concept for validating OpenBao as an identity provider. The goal was to confirm it could handle credential management and JWT signing before building Kenoma on top of it.

vassago_docs_util

GitHub ↗

CLI I built to stop writing READMEs by hand. Points it at a repo, repomix extracts the source, Claude Haiku generates the docs in whichever mode you need. Shows token cost before it sends anything.

Kenoma In Progress

GitHub ↗

Base layer for distributed multi-tenant services. Raum stores database connection metadata and issues short-lived credentials through OpenBao. Vassago is the client-facing gateway. Together they provide identity to multiple tenants across different databases, designed so future modules can plug in on top.
