About

I'm Edwin Stoltz, a cloud engineer and value investor based in South Africa. I spend my days building data infrastructure on AWS' Platform and my evenings digging into JSE-listed companies looking for mispriced value on GCP.

This blog sits at the intersection of those two interests. I write about cloud engineering, data pipelines, programmable banking, and value investing — often combining them into projects that automate the boring parts of personal finance or turn raw financial data into actionable insight.

What I write about

  • Cloud & Data Engineering — GCP, AWS, BigQuery, Terraform, serverless architectures, and data warehouse design.
  • Programmable Banking — Building on Investec's Open API to automate savings, categorise transactions, and create personal financial dashboards.
  • Value Investing — Screening JSE stocks using Buffett-Munger principles, building automated valuation pipelines, and honest write-ups when bets go wrong.

Why this blog

I'm not just bored — I'm ready for something new. Well, maybe a little bored. But honestly, there's more to it than that. I want to explore new paths, challenge myself, and help both myself and others find success along the way.

If any of this resonates, feel free to get in touch.
