Software Mind
- Led content refinement initiatives for AI-driven mechanical engineering tasks by building Python pipelines that validated formulas, cross-checked references, and standardized complex engineering explanations to improve LLM reasoning accuracy by a measurable margin.
- Created highly detailed mechanical-engineering task scenarios for LLM training by combining domain principles such as statics, thermodynamics, and mechanical failure modes with programmatic Python validation tools that ensured correctness and reproducibility.
- Audited expert submissions using structured review rubrics, verifying mechanical-engineering knowledge depth, detecting inconsistencies, and rewriting unclear sections to ensure alignment with strict project guidelines and scientific accuracy.
- Moderated expert discussion channels on Discord, providing technical clarifications on mechanical-engineering problem statements, guiding contributors on best-practice prompt patterns, and resolving ambiguities to keep workflows efficient and consistent.
- Built Python scripts for automated content-quality assessments that checked dimensional consistency, validated engineering assumptions, and flagged potential hallucinations or domain errors before content was passed to the LLM training pipeline.
- Reviewed qualification exams for incoming mechanical-engineering experts by analyzing multi-step reasoning chains, verifying computational accuracy, and identifying knowledge gaps to maintain a strong contributor pool for AI-driven engineering tasks.
- Developed structured reference examples for complex topics like stress analysis, material behavior, and system dynamics, ensuring that LLM training data contained clear progressive steps, relevant terminology, and precise real-world engineering analogies.
- Collaborated with AI researchers to refine prompt templates used for engineering task generation, ensuring templates enforced clarity, step-by-step reasoning, and alignment with proper domain-specific methodologies.
- Implemented Python-based content transformations that normalized language style, added structured breakdowns to long engineering solutions, and enhanced feature completeness of mechanical problem explanations for more robust LLM training datasets.
- Partnered with cross-functional ML teams to analyze LLM evaluation outputs, identify systemic mechanical-reasoning weaknesses, and iteratively improve the dataset by injecting higher-fidelity examples, accurate boundary-condition setups, and real-world engineering patterns.

- Led Python-based backend development for a data-centric platform while contributing to AI-related content-quality pipelines that evaluated engineering correctness, enabling the platform to manage expert-reviewed datasets at scale.
- Reviewed and audited technical contributions from domain experts, ensuring explanations matched scientific standards and rewriting unclear reasoning steps to maintain a high-accuracy knowledge base for downstream AI usage.
- Built automated review tools in Python that analyzed expert-submitted tasks, checked for structural completeness, validated numerical consistency, and ensured each submission aligned with mechanical-engineering logic patterns.
- Supported expert onboarding by evaluating qualification assessments, identifying reasoning flaws in mechanical scenarios, and providing actionable feedback that improved contributor quality and reduced review iteration cycles.
- Moderated internal discussion channels by answering technical questions, clarifying domain interpretation issues, and enforcing contribution guidelines to keep all task submissions aligned with unified mechanical-engineering standards.
- Developed Python micro-services that handled structured content ingestion, metadata tagging, and engineering-task transformation, ensuring datasets were consistent, searchable, and ready for model-training workflows.
- Worked closely with reviewers to craft step-wise mechanical-engineering examples, bridging theory and calculation logic in formats optimized for LLM comprehension and error-free reasoning performance.
- Designed workflow improvements that reduced review friction by standardizing task formats, creating guideline checklists, and helping experts adapt quickly to challenging or unusual mechanical-engineering prompts.
- Participated in internal AI-model evaluation cycles by systematically checking model outputs, identifying failure modes in mechanical-reasoning steps, and drafting refined examples that corrected flawed logic patterns.
- Mentored junior contributors on Python best practices and systematic reasoning structures, teaching them how to convert mechanical-engineering concepts into clear, machine-readable, instructional content.
