Experience[3y 0mo]

Perssonify & Virallens

  • Built the Perssonify company website from scratch in Next.js, Tailwind CSS, and Framer Motion — owning the full frontend from layout and design system to animations and production deployment.
  • Built HelixCrawl, a high-throughput web-crawling platform on a fully Go (1.25) microservices backend, processing ~50K pages/day across nine specialized services (bfs-frontier, crawl-engine, doc-parser, http-fetcher, and more).
  • Designed the HelixCrawl data pipeline around Kafka, Redis, and bloom-filter deduplication, enabling reliable concurrent crawling at scale without redundant fetches.
  • Engineered HelixCrawl's anti-bot fetching layer (TLS fingerprinting via utls + go-rod), lifting successful crawl rates on protected targets from ~60% to ~90%.
  • Re-architected the crawl backend from a Celery/Temporal pipeline to a Kafka-driven Go system, tripling throughput (~3x) while cutting infrastructure cost by ~35%.
  • Designed and built the UI dashboard for the Stock Drop Analysis platform, a securities-fraud detection tool for law firms — delivering a clean, law-firm-grade interface in IBM Plex Sans with a teal/navy design system.
  • Built Content publishing platform now used by clients in production — powering blog content published live on the ZLK (Levi & Korsinsky) website.
