The journey, so far.

My work across four companies: the problems I took on, the decisions behind the code, and what changed after it shipped.

APPLIED AI / PRODUCT ENGINEERING

Search discovery, AI profiles, and candidate matching.

I improved search discovery, built AI-assisted profile features, and worked on matching explanations. Evaluation and tracing helped the team check what those features were doing.

Google-indexed pages: +1,700%Growth in indexed candidate and company pages after the sitemap improvements.
Candidate shortlists: +22%Increase in recruiter shortlists in profile-optimization experiments.
Candidate rejections: −20%Reduction observed in the profile-optimization experiments.

Better discovery, clearer career evidence, and more explainable recruiting decisions.

PAGE VISIBILITY

Only public pages belong in the sitemap

Public pages enter the sitemap so search engines can find them. Private pages stay out of the list.

How discovery works

A sitemap gives search engines a list of pages to discover. It helps crawlers find content, but does not guarantee indexing. Page access controls remain separate from sitemap inclusion.

My sitemap work improved the discoverability of public pages.
