Marcelo Santos

Staff+ software engineer focused on software architecture, domain modeling, and event-driven systems.

I build backend tools and reusable engineering workflows, with a focus on clear domain boundaries and predictable runtime behavior.

I care about explicit contracts, failure handling, and changes backed by review and tests.

Selected projects

Project What it does
Cascade Declarative message pipelines built with YAML, TypeScript, and Effect.
Accord Early-stage domain modeling in TypeScript: aggregates, events, SQLite persistence, and optional Effect integration.
Chimpbase A TypeScript backend runtime for actions, queues, schedules, and HTTP routes, backed by PostgreSQL or SQLite.
Skills Reusable workflows for planning, testing, code review, documentation, and delivery with coding agents.

See each repository for setup, examples, and project status.

Writing and contact

I write about software architecture and engineering practice in Portuguese.
