Engineering

This is a tale of software architecture decision-making in large companies. The setup As part of my job as a software architect, I had to design a solution which involved the integration between 2 systems: let’s call them A and B. They were part of a new instant payment processing flow that was beeing developed. System B had a legacy integration mechanism that was no longer supported at the architectural level.

Proof-Driven Development (or — the business value of Clean Code) In the Algorithms course I took at college (back in the late ‘90s…) we’ve learned to prove the correctness of certain …

Dig in to the original goals of the Postgres academic project at UC Berkeley and how they shaped the Postgres we use today.

The Timeless Way of Building by Christopher Alexander is a classic text on real-world architecture. In computing, it was influential in the emerging field of object-oriented programming in the late 1970s and 1980s. The book still has much to teach us about how we think about software design.

Learn how to use rich types, phantom types, and partial application to eliminate impossible states and implement Clean Architecture's dependency inversion in a functional way. Discover why the compiler is your best friend for building robust domain models.

Most of what modern software engineers do involves APIs: public interfaces for communicating with a program, like this one from Twilio. I’ve spent a lot of time…

This blog is an attempt for anyone lost to find their way into observability and a wake-up call for devs to they should think about observability more actively today than ever before.

Why doing the absolute minimum is a gift in software engineering. \n

Decoupling a monolith is not a rare problem. It appeared in most of the companies I worked in. This happens because, at the early stages of any startup, there is so-called decision debt being…

This article dives into the throughput and quality of the async code review process and explains co-creation patterns – Pair and Mob programming – as an alternative way of working.
