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.
