Under The Hood

Pretty interfaces are easy. What's underneath is where it gets interesting.

01
Architecture
  • Event-driven pipelines for real-time observability (Velyn)
  • Multi-tenant SaaS patterns across products
  • Public SDK design — APIs used by other devs in production
  • Service layer separation, domain modeling
02
Backend
  • NestJS + Node.js for production-grade APIs
  • Auth, RBAC, multi-tenancy from scratch
  • MySQL schema design, MongoDB document modeling
  • Webhooks, background jobs, queues
03
Engineering
  • Leading and reviewing code for a team
  • Balancing product velocity vs. tech debt
  • Full-stack shipping — solo, across 3 live products
  • All products maintained and iterated in parallel
