About quadratic²

Hey, I am Ilija 👋 Nice to meet you!

Every week I publish an article on topics related or adjacent to product engineering. Quadratic tries to pay respect to the unsung heroes of our industry - product engineers, who build delightful experiences for their customers.

If you are a product engineer who wants to level up and learn how to truly build scalable products and experiences that delight their users, this is the place for you.

Here’s some writing from the past:

I strongly believe that you will not find a better publication aimed at product engineers.

About me 🙋‍♂️

I am a senior software engineer, working with the fine folks over at Stripe on the Stripe Tax team. Before that I worked with some great people in Scribd, Catawiki and in Siyelo.

In my career now spanning ~10 years my roles have varied from a full-stack developer, to technical leader, backend software engineer, and even moonlighting as a product manager.

Throughout my career I have been fortunate to collaborate and be challenged by invigorating people. I have worked on ambitious projects and have had to set up foundations for others to build upon while solving interesting problems.

This newsletter is my attempt to write the content I have always wanted to read. How to engineer products, collaborate well with cross-functionally, write well, and grow personally in the process.

I would love to have you on board 🚢
