Hi, I'm Hidekel (Niko) Irizarry 👋

Mechanical Engineering student at UCF — building things that simulate the physical world.
Self-studying machine learning on the side, working toward the intersection of engineering and AI.

 


Featured Project

A complete finite element solver for planar truss structures, built from scratch in both Python and JavaScript. Uses the Direct Stiffness Method — the same algorithm behind ANSYS and Abaqus.

Truss Solver Preview

Given any truss (nodes, members, supports, loads), it assembles the global stiffness matrix K, solves K·u = F for displacements, computes reaction forces and axial member forces, and renders a color-coded visualization (green = tension, red = compression).
