About Me

  • Currently building MovieMatch, a movie recommender that learns your taste
  • I enjoy designing databases and putting business logic where it belongs
  • I like networking work: TCP/UDP protocols, client–server systems and reliability
  • I'm exploring machine learning: EDA, classification and recommender systems
  • I care about secure software: authentication, access control and OWASP-minded design
