- CRM migration: Moved a UK agency's 18 GB legacy CRM, with no declared keys, into a SaaS CRM that could only be written through its REST API. Nothing lost, nothing invented.
- LLM matching for a Japanese recruiting platform: Recruiters type a job description and get a ranked shortlist with reasons, in English and Japanese, fast enough to use live.
- Evals that tell the truth: My first result said +30%. I didn't trust a number that good, found the artifact, and reported +12.9%.
- RefineCV: A B2B SaaS that turns any CV (PDF, DOCX, scans) into an agency-branded document, sold to recruitment agencies.
- Recruiter Copilot: A Chrome extension that scores every LinkedIn profile 0–100 against a job description, with pros and cons.
- Fine-tuning Mistral-7B with DPO: With three college friends I built the backend of an AI wellbeing companion, then fine-tuned Mistral-7B when the base model wasn't good enough.
- The Studio: an AI content engine: One engine runs several short-video channels: an AI agent drafts, local models render, and nothing goes out without my approval.
- Freelance: agent evals and automations: Graded AI coding agents against real upstream bugs, and built duplicate-safe automations for small businesses.
