SEO for Software Engineer Portfolios
You will not outrank LinkedIn for the query software engineer. That is fine. The goal is to own your name, your niche, and long-tail searches that match what you actually do.
A clean title (your name), a human meta description, JSON-LD Person and FAQ schema, robots.txt pointing to sitemap.xml, and crawlable HTML for SPAs. Google runs JavaScript, but prerendered snapshots for key routes remove doubt.
Favicons must exist as real PNG/ICO files at stable URLs. Open Graph images need absolute https:// URLs, not relative paths.
