## Interactive applications

- [AeroLab 2D](https://alexengineer.net/aerolab/): Browser-based NACA airfoil laboratory combining a WebGL 2 D2Q9 lattice-Boltzmann flow solver, Hess-Smith panel method, integral boundary-layer model, pressure and force plots, and engineering diagnostics.
- [AeroLab 3D](https://alexengineer.net/aerolab-3d/): Browser-based aerospace laboratory for vortex-lattice aircraft analysis, viscous performance estimates, Barrowman rocket stability and drag, and atmospheric re-entry simulation.

## Selected engineering work

- UCI CubeSat Structures: static and modal analysis plus FlatSat V1 systems-integration hardware.
- Mission to Didymos: MATLAB astrodynamics, Lambert transfers, delta-v analysis, and launch-window mapping.
- OBD-II Read-Only Diagnostic Dashboard: local FastAPI and WebSocket diagnostics with a protocol-level read-only safety contract.
- Photon Paths Near a Black Hole: MATLAB computational-physics simulation and visualization.
- Autonomous Robot and PID Controller Design: controls, experimental verification, and technical reporting.
- ExtrakPak SAR Drone Concept: aerospace systems proposal, operational framing, and risk analysis.
- Hands-on Mechanical Project Logs: documented suspension, braking, lighting, exhaust, diagnostics, and installation work.

## Notes for agents

- The interactive labs run entirely in the browser and require JavaScript and WebGL 2 for their full visualizations.
- Public reports, project files, and the current resume are linked from the project archive.
