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
Loyalty and rewards platform for a business: employees grant points to customers, who redeem them for rewards through employee-verified exchange codes. Includes an admin approval flow for exchanges, top-client/top-reward stats, and JWT auth for both employee and customer roles. Currently with a ready points store, with plans to grow into a full fidelity system.
Privacy-first B2B SaaS platform I'm building: a reactive, multi-tenant microservices system providing authentication, organization management, secrets handling, and inventory management as composable backend services. Fronted by nginx, with a React admin UI and a Grafana/Loki/Prometheus observability stack.
Kenoma's organization and credential registry. Provisions tenants, registers services, and issues short-lived database credentials through OpenBao so downstream services never hold long-lived secrets. Also owns billing: per-module pricing, multi-currency invoicing, and disaster-recovery backups.
Kenoma's authentication and identity service. Issues and validates ES256 JWTs via OpenBao's transit engine, manages sessions in Redis, and handles the full user lifecycle, including email-based password recovery.
Kenoma's multi-tenant inventory service, with tenant data isolated at the data layer. Supports products with configurable metadata, multi-option variants, an append-only stock ledger, and low-stock alerts.
