How I Approach Problems

A few things that show up consistently in how I work:

Test-Driven Development — Writing tests before code isn't just a methodology; it's a way of thinking through requirements precisely before committing to an implementation.

Benchmark before optimising — Opinions about performance are cheap. Numbers aren't. I tend to measure first before drawing conclusions.

Clean architecture in constrained environments — Power Platform has limits. Combining it thoughtfully with Azure (Functions, Service Bus, etc.) opens up better patterns without fighting the platform.

Writing as learning — Blogging consistently since 2015, covering real problems encountered in real projects. Not tutorials for beginners, but working notes from the field.

Open Source

A couple of public projects on GitHub:

  • Niam.Xrm.Client — A wrapping framework that simplifies Dynamics CRM / Model-Driven Apps front-end customisation
  • pcf-form-json — A PCF component that renders a predefined JSON string as a form and returns the result as JSON

Writing

I write regularly on technical topics at temmyraharjo.com. Recent topics include:

  • AI-powered summaries for Power Platform solution changes via GitHub Actions
  • Concurrency patterns in Dataverse using Azure Service Bus
