Top SchoolSergey Tulentsev is a senior software engineer with 17 years of professional experience and 20+ years scaling backend systems across startups and large companies.

His background spans payments at Stripe, high-throughput social analytics (peaking at ~5k writes/sec), and full-stack work that improved API endpoints by orders of magnitude, reflecting a pragmatic focus on measurable outcomes.
