Software Architecture

System design work for products that have outgrown their first architecture — multi-tenant data isolation, event-driven processing, and API contracts that can serve more than one client.

System DesignMulti-TenancyPostgreSQLRedisBullMQ

What you get

  • A data model and tenant-isolation strategy that scales past the first client
  • An event-driven background architecture for anything that doesn't need to be synchronous
  • An API contract designed to serve mobile, web, and third-party integrations from one backend
  • A migration plan from an existing architecture, where relevant

Who it's for

  • Products scaling from single-tenant to multi-tenant
  • Teams hitting request-path bottlenecks from synchronous work that should be queued
  • Founders who need a second opinion on an architecture decision before committing to it

How I work

  • Start from the data model and tenant boundary, not the framework choice
  • Identify what actually needs to be synchronous versus what can be queued
  • Design for the API consumers that exist today and the ones likely to exist in a year
