Software Engineer Intern

Light RFP

Jun 2026 - Aug 2026

Built a public directory for 679K+ vendors and enrichment pipelines using scraping and AI for production-ready pages. Reduced search from 4.35s to 152ms by replacing queries with prebuilt facets, bounded counts, trigram GIN indexes. Fixed production vulnerabilities like stored XSS, broken access control, SSRF, and added security headers like CSP.
