Detailed notes about architecture, Firebase, offline systems, SaaS boundaries, POS transactions, payments, real-time features, and the decisions behind maintainable applications.
True multi-tenancy is enforced at the database security boundary—not through fragile WHERE clauses in your Flutter client code.
Handling thousands of price updates per second without freezing the UI thread requires strict event throttling and isolate processing.
Automated pipelines transform store releases from an anxiety-inducing chore into a single git tag or pull request merge.
Production Flutter work is a sequence of risk-reduction decisions—not a sprint from mockup to store build.
Architecture succeeds when common changes stay local and important workflows remain easy to reason about.
Firebase scales best when data ownership and query patterns are designed before collections start growing.
I can help translate architecture and reliability concerns into working Flutter, Firebase, API, and SaaS product decisions.
