Marcos Lara: Full-Stack Developer, Database to Deployed UI

rfc-lara-1

Status of This Memo

This memo describes a developer who is available for full-time and lead roles, and for freelance or partnership work. Distribution of this memo is unlimited.

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.

  • The author MUST ship to production.
  • The author MUST own the whole stack: database, API, interface and deployment.
  • The author SHOULD say when a product did not survive.
  • The author MUST NOT claim anything this document cannot link to.
  • Recruiters MAY skip straight to Section 6.
