I help robotics, energy, motor-drive, and power-electronics teams turn control and estimation problems into working, validated systems — fast, and backed by the math. PhD researcher in control & automation. I design controllers, build high-fidelity Simulink/MATLAB and Python simulations, identify models from data, and train reinforcement-learning policies — then prove they work against both the equations and the data. I've published first-author research in IEEE Transactions on Cybernetics on data-driven, adaptive, and nonlinear control. Where I'm strongest: • Motor & power-electronics control — field-oriented control (FOC) of PMSM/BLDC drives, current/speed loops, cross-coupling decoupling, anti-windup, in Simulink/Simscape • Data-driven control & state estimation — system identification, Kalman filters and unknown-input observers, fault/anomaly and cyber-attack detection for power systems and microgrids • Reinforcement learning for control — Gym/MuJoCo, PPO/SAC, reward shaping, sim-to-real • Paper reproduction & algorithm implementation — clean, runnable code with figures that match the original Recent work (public on GitHub): • PMSM field-oriented-control speed drive, built programmatically in Simulink • Data-driven unknown-input observers that detect and localize false-data-injection attacks in a DC microgrid (IEEE method, reproduced end-to-end) • Soft Actor-Critic swing-up of an inverted pendulum Why me: I'm not a generalist who "also does control." I read the paper, derive the math, build the model, and validate it — so you get a result you can trust, not a black box. I move fast with modern tooling, but correctness comes first. Scope: I do legitimate engineering, reproduction, simulation and analysis. Send me your plant, your spec, or the paper — I'll tell you how I'd approach it and what the first deliverable looks like.

Hi, I'm a 𝑫𝒆𝒏𝒕𝒂𝒍/𝑴𝒆𝒅𝑻𝒆𝒄𝒉 𝑺𝑻𝑳 𝑷𝒊𝒑𝒆𝒍𝒊𝒏𝒆 𝑬𝒏𝒈𝒊𝒏𝒆𝒆𝒓 specializing in 3D mesh geometry and CAD/CAM automation. I build production-grade Python and C++ tooling that converts raw intraoral-scan STLs into precision, print-ready tooth-preparation guides — automated offsetting, variable-thickness shelling, boolean slot/slit cutting, and watertight validation, fully batch-ready. 🤝 I deliver geometry that manufactures, not just renders. My pipeline approach: Scan Intake → Mesh Repair → Parametric Offset → Variable-Thickness Shell → Boolean Feature Cuts → Watertight QA → Print-Ready Export. What sets me apart: deep computational-geometry fundamentals (mesh offsetting, B-rep/CAD kernels, non-manifold repair) fused with hands-on anatomical CAD/CAM experience.
