What I'm looking for

I'm available for remote, full-time, contract, or research-based roles.

At Outlier AI, I refined machine-generated transcripts and responses for technical and financial domains, correcting terminology and speaker attribution. My work reduced critical errors by 95%, and I created timestamp-aligned transcript deliverables and tracking logs.

At Alignerr AI, I review, rank, and annotate AI-generated responses through RLHF. I fact-check claims and reasoning, assess code snippets, and design edge-case prompts to evaluate model behavior and safety.
