Joachim (Marnu) Grobbelaar
SciML & Autonomous Systems
Senior Systems Developer, Physicist, and SciML Engineer. Creator of the NanoDynamics symplectic Hamiltonian PINN simulation suite and the Swarm-Nexus zero-deletion multi-agent autonomous fleet.
Core Systems & Scientific Implementations
Production-grade astrodynamics tools, neural surrogate models, and multi-agent systems designed, tested, and maintained by Joachim Grobbelaar.
NanoDynamics — Earth-Moon PINN Orbital Simulator
Symplectic Hamiltonian neural surrogate predicting low Earth orbit decay, J2–J4 oblateness perturbations, and 3-body Lagrange points. Features 18+ interactive 3D WebGL spacecraft models and real-time ESP32-S3 Hardware-in-the-Loop telemetry.
Swarm-Nexus — Autonomous Multi-Agent Coordinator
Autonomous task decomposition and parallel execution engine coordinating OpenAI Codex, Google Antigravity, and GitHub Copilot across isolated worktrees with strict zero-deletion safety invariants and Redis DB 0-2 caching.
Sovereign Telemetry & Database Standby Mesh
Distributed observability stack with sub-second health probes, HostAfrica MySQL replication with local SQLite standby fallback, HostAfrica SMTP email relays, and automated recovery loops across all services.
