About

I'm Alex — a Senior Principal Software Engineer and Platform Architect in fintech, building internal developer tools and platforms that scale.

Previously, I built trading and financial systems at Credit Suisse in Brazil.

I call myself "The Platform Toolsmith" because I'm an architect who still ships code. I design systems, but I also build the tools that make those systems work. This blog documents what I build and why.

Work With Me

I'm always interested in:

  • Speaking — Talks on platform engineering, developer experience, and building internal tools
  • Collaboration — Open source projects, technical writing, or podcast appearances
  • Mentoring — Helping engineers grow into staff+ and leadership roles

Mentoring

I mentor engineers navigating the transition from senior to staff+ roles. Sessions focus on technical leadership, platform engineering, and career strategy.
