Modular Monoliths, Multi-Tenancy & High-Velocity B2B Systems
Battle-tested systems design for software founders. Avoid premature microservices, enforce domain boundaries, and scale with PostgreSQL row-level security.
Practical, code-backed engineering teardowns for saas & systems architecture.
Naive B2C auth breaks the moment enterprise teams sign up. Learn how to architect multi-tenant workspace switching, granular RBAC, and SSO-ready schemas from Day 1.
Eliminate HTTP 504 timeouts and dual-write bugs in your SaaS MVP. Learn why Postgres-backed queues outperform Redis and Kafka for early-stage startups.
Eliminate cross-tenant vector data leaks in enterprise AI SaaS. Learn deterministic RAG isolation patterns using pgvector RLS, metadata pre-filtering, and strict namespaces.
Avoid burning $2,000/mo on idle Kubernetes clusters. Learn how a modular monolith maximizes shipping velocity and investor-ready architecture for your MVP.
Learn how PostgreSQL Row-Level Security delivers enterprise-grade multi-tenant isolation on a single database without complex infra or cross-tenant data leaks.
Non-negotiable architectural practices we implement across founder codebases to prevent premature rewrites and ensure investor-grade quality.
Never introduce distributed microservices until a single compute runtime cannot sustain load or when multiple autonomous teams require separated deployment boundaries.
Enforce multi-tenant data isolation directly at the database engine level via RLS policies rather than relying on brittle ORM application-level WHERE clauses.
Use typed in-process event buses for domain module separation. Postpone external cloud queue brokers until multi-instance background workers are required.
Expose only designated public module contracts via index.ts and prohibit cross-domain internal imports with compiler and linter rules.
