Abstract
I'm Marcos Lara, a full-stack developer in Belo Horizonte, Brazil, with 8+ years of experience. I design, build and run web platforms end to end: database schema, API, interface, and the deployment behind them.
Buddi, Membra and Seeng are in production right now and documented in Section 2. To hire me, see Section 6 or write to contact@dbug.me.
1. Introduction
For 8+ years I've taken products from an empty repository to production: the schema, the API, the interface, the deployment, and the parts nobody demos, like billing and reports.
I lead development at Buddi and I'm a founding member of Seeng. This document is how I work, written down, with every claim linked to something you can open.

1.1. Requirements Language
The key words MUST, MUST NOT, SHOULD and MAY in this document are to be interpreted as described in BCP 14 [RFC2119]. In the list below, each keyword links to its evidence.
2. Running Implementations
The following implementations are in production at the time of writing. Each figure is a real screenshot; it is drawn from characters as it enters the page. Point at a figure to see it as characters again.
