Final-year Mechanical Engineering (B.Tech) student with a focus that goes past standard coursework FEA — I write and debug custom Abaqus material subroutines (UMAT) in Fortran, not just run built-in models. Recent work: reviewed and debugged a coupled thermomechanical shape-memory-alloy (SMA) constitutive UMAT — catching an incorrect transformation-strain direction tensor (causing ~18% underprediction), a memory-safety issue when NTENS ≠ 6, a missing corotational rotation of tensor state variables, and a secant-vs-consistent-tangent stiffness problem. I also build Python tooling for inverse material-parameter identification (Gauss-Newton / Levenberg-Marquardt refinement against nanoindentation and tensile-test data), and I'm developing my own browser-based FEA/material-characterization platform on the side — this is an active interest, not a one-off skill. What I take on: nonlinear implicit/static analysis, custom material model (UMAT/USDFLD) development, Abaqus Python scripting for parametric or repetitive workflows, and material-parameter identification from experimental test data. Happy to start with a smaller, well-scoped task first so you can evaluate the work before a bigger commitment.

I am a Mechanical CAD Designer and Mechatronics Engineer specializing in 3D modeling, mechanism kinematics, and structural simulation for aerospace and robotics. Core Strengths & Skillsets: 3D CAD & Simulation: SolidWorks, PTC Creo, Fusion 360, and Ansys. Additive Manufacturing: Optimizing geometries for FDM 3D printing with engineering composites (PA6-CF, PC-ABS, TPU). Drafting: Production-ready 2D drawings with strict GD&T. Key Projects & Education: UAV Systems: Led 3D CAD design and structural simulation for a military drone swarm (Indian Army Internship) and an internationally award-winning heavy-lift multirotor. Robotics: Authored published research (Springer Nature) on the kinematic CAD assembly and 3D print optimization of a 6-DOF robotic arm. Education: B.E. in Mechatronics Engineering, Thapar Institute of Engineering & Technology. I prioritize clean CAD architecture, functional reliability, and clear communication.
