Senior Software Engineer · AI-Augmented

Backend architecture for fintech & B2B SaaS — distributed systems in Node, TypeScript, and AWS.

What I do

I drive backend architecture at Xenia — a B2B SaaS platform for 10,000+ deskless workers. 5+ years across fintech and B2B SaaS, focused on distributed systems, performance, and reliability.

I work in an AI-augmented style — Claude Code with custom skills, plugins, and parallel agents. Established AI-native service docs across our repos that cut new-engineer onboarding by 70% and lifted sprint throughput 3×.

Recent work at Xenia

  • Real-time analytics on CDC + ClickHouse — offloaded 70% of read traffic from primary databases
  • Enterprise SSO via WorkOS (SAML, Google, Azure AD) — onboarded 10+ enterprise clients with zero auth incidents
  • Offline-first mobile sync for low-connectivity environments — cut data loss by 90% across 10,000+ field workers
  • AWS RDS tuning — reduced CPU 50%, saving ~$3K/month
