Hi there!

I'm Daniel, a Senior Full Stack Developer based in Amsterdam, working at iPractice, a company focused on making mental health care accessible to everyone.

I specialize in architecting, designing and developing scalable software solutions on Azure and AWS. I also use AI-driven tooling daily, from code reviews and monitoring to generating tests and scaffolding features.

On the backend, I'm experienced in .NET, Go, Python and SQL. On the front, I'm experienced in TypeScript & JavaScript (React, Astro, Solid, HTMX). Most recently, I've been working with React Native and Expo. I use LLM tooling and automation heavily in my daily workflow, to stay fast and focus on the parts that actually need a human.


Daniel Agg

I advocate for modular monoliths with vertical slicing, Domain Driven Design, true CI/CD with Trunk Based Development and feature flags, fitness functions, procedural code and compartmentalizing volatile parts of our applications.

I'm passionate about researching adaptable software architectures, enabling applications to gracefully evolve over time: I came to realize the value of an adaptable architecture, which can facilitate the ever-changing landscape of business needs and keep the tempo of development rapid, without accumulating technical debt. I use AI tooling the same way: to automate code reviews, generate and maintain tests, triage production issues and turn repetitive engineering chores into prompts and pipelines.

While I love geeking out over architectures, I like to think that I'm also pragmatic, always keeping in mind that my goal as a software developer is to deliver a working product, not the blueprint of it.
