ML &NN - Stellantis ML Generator:

• I/O Parameterization: Developed workflow automation for parametric data extraction, including loadcase-specific implementations.
• Exploratory Data Analysis (EDA): Designed modules to identify missing/duplicate values, detect outliers, summarize data, and interpret results. Conducted sensitivity studies for linear and nonlinear design variables and applied correlation techniques to analyze variable contributions.
• Auto ML Development: Built an automated machine learning framework to train models using various algorithms, optimizing for the best-performing model with suitable parameters.
• Neural Network Implementation: Developed basic architectures for CNNs, RNNs, and ANNs to handle image datasets, time series data, and other applications.
• Design of Experiments (DOE): Integrated functionality to generate DOE data as an addon feature for the tool.

Generative AI - Stella Script AI (Azure Databricks):

• API Extraction: Leveraged cross-encoding techniques (all-miniLM-v12) for efficient extraction of ANSA and METAPOST APIs.
• Code Synopsis Generation: Developed code synopses using advanced prompt techniques with CodeLlama-13b-Instruct-hf.
• Code Generation: Implemented code generation pipelines using RAG Architecture with CodeLlama-13b-python-hf.
• Error Detection & Auto-Fix: Designed a system to identify and automatically fix syntax errors in code.

PINN - Microsoft Structure & Scalable

• Physics Informed Neural Network : Developed a simple PINN for simple hormonic motion and steady state 1D flow for navier stoke equation.
• End to end learning in terms of Git, PR generation and microsoft azure cluster handling.

• Identified automation opportunities across CAE domains (durability, safety, NVH, etc.) to streamline processes and enhance efficiency.
• Created over 100 automation tools, saving approximately 20,000 man-hours per program.
• Worked extensively on integration of all developed scripts into single tool named as FCA Integration Toolkit.
• Worked extensively on automation of various CAE process automation tool such as Joint Stiffness Analysis, Brake Pedal Analysis, Skid Plate Analysis, Roof Snow Load Case, Roof Cargo Load Case, Tow Eye, Tow hook, Hood Torsion, Hood Lateral, Hood Overload, Seal Load Compensation Analysis, Engine Roll Wiring Harness, Brake rotor process automation tool and Load Deflection Analysis process automation tool.
