Labeling Experience

Research & Simulation Engineer — Battery Design Engine (IIT (BHU) Varanasi)

OtherDocument

Built and validated a physics-based simulation engine for lithium-ion cells by cross-referencing computed outputs against provided ground-truth spreadsheets. Authored tolerance-based regression test cases to isolate edge-case configuration gaps, applying a workflow comparable to AI output evaluation and fact-checking. Reconciled discrepancies across multiple computed variables and documented each correction for traceability. • Validated 99.9% computational accuracy across 8 functional domains • Created 25 regression test cases for edge-case coverage • Performed discrepancy analysis and written documentation of fixes • Developed an AI-assisted workflow using LLM tools for validation and technical documentation
