Red Teaming & RLHF for Compliance-Safe LLM Training

TextRLHF

I did a mix of red teaming and RLHF. Basically, I tried to break the model by asking tricky questions that might get it to leak private info (PII, PHI) or give unsafe advice. I also ranked responses for how helpful vs. harmful they were. On top of that, I reviewed Python and SQL code the model generated — checking for correctness and security issues. All together, I completed around 2,500 tasks, including 500+ detailed write-ups on model failures.

Skill Extraction & Coding Task Review for Job Matching Models

TextComputer Programming/Coding

I annotated job descriptions and student profiles to help their recommendation algorithm get better at matching people to roles. A big part of the work was tagging technical skills — Python, SQL, AWS, Tableau, that kind of thing. Because of my engineering background, I also reviewed model-generated coding task examples and flagged the ones that were incorrect or poorly written. I went through about 8,000 job postings and 3,500 profiles. I also did evaluation ranking to compare different versions of the skill-matching model.

Prompt Writing & Function Calling for Healthcare Finance AI

TextPrompt + Response Writing (SFT)

I worked on training an LLM for healthcare and financial use cases. Most of my time was spent writing example prompts and ideal responses — things like explaining prior authorization denials or pulling claims data. I also helped design simple function-calling workflows so the model could interact with external APIs. On top of that, I did RLHF ranking, comparing two model responses side by side and explaining which was more accurate and safe. Finished over 1,500 ranking tasks across a bunch of model versions and stayed above 90% agreement with quality checks.

Legal Document Entity Extraction & FOIA Redaction for LLM Fine-Tuning

TextEntity (NER) Classification

I worked on a legal AI project where I labeled sensitive government documents, mostly FOIA-related records. The main goal was identifying PII, dates, case numbers, and exemption categories to help train a model for automated redaction. I also did some red-teaming on the side — basically trying to trick the model into over-redacting or leaking info so the team could fix weak spots. In total, I went through roughly 15,000 document chunks. We had regular calibration sessions to stay aligned, and I consistently hit above 95% agreement with other reviewers.
