druvu

Modular Java libraries and JVM tooling, built to last.

Small, focused open-source Java — from options pricing and GnuCash to JMX and JVM diagnostics. Maintained by one engineer.

---

Finance & accounting

Options pricing and Greeks (options-math), and GnuCash read/write through a clean Java API (druvu-acc). Backed by trading-systems domain experience: matching engines, FIX Protocol, STP, market data, financial risk monitoring, xVA, swaps, forwards, futures, spots, FX.

JVM tooling

JMX over JMXMP without the legacy baggage (druvu-lib-jmxmp), and JConsole enhancements for JVM diagnostics and monitoring (JConsoleBooster).

Libraries & foundations

Small modular building blocks: a JPMS-friendly ServiceLoader wrapper (druvu-lib-loader), JDBC helpers (druvu-lib-jdbc), and web utilities (druvu-lib-web). Full Java Platform Module System support throughout.
