Bol.com’s big Data Journey

As techlead on bol.com’s technical platform my responsibilities include how we work with BigQuery. For us it’s not just a way to park a lot of data. It is a place where development teams store their data so that the rest of the business can get their insights and analysis. Our analytics use cases ranges from insights such as margin, price and stock at the product level all the way up to overall corporate performance. While we look back, we also look forward using Machine learning and AI to accurately…

This year the bol.com Spaces Summit was held virtually and Anastasija and myself, Quiran Storey, presented a talk on a topic that is close to our daily work “From prototype to production. A real-life cloud story.” About the talk All things start out as ideas, or prototypes, and our R2D2 is no different. In this talk we will give you a glimpse of how bol.com’s self-service cloud provisioning tool came to be. But also how it is constantly evolving from a proof of concept to a full-on production system. We…

Spaces Talk #2: Introduction to Sociotechnical Architecture

I’ve had the great pleasure of giving a talk at the Spaces Summit 2020, the internal bol.com Tech conference. About the talk Maximizing the impact of our products is more than just thinking about their technical architecture. Doing so would lead to just partially optimizing their potential impact. Instead, we need to follow an approach that also recognizes people (i.e. the teams building the products) as a central element in the design space. This way of co-designing is termed “Sociotechnical Architecture”. In my talk on this topic, I first lay…

Introducing Stanley: bol.com highway to (heaven) BigQuery

Yes, it’s confirmed! Bol.com is going to the Cloud! The contract with Google has been recently signed, which gives us about 1 year to migrate from Platfora (our BI visualization tool), before it stops having support. 1 year thus to migrate many datasets and dashboards to the Cloud. The tools in Google Cloud are great, and our colleagues are too; so, what could possibly go wrong?… At least this is what we thought in 2017… Our Big Data situation in 2017 Bol.com was storing its Big Data on Hadoop…

Refactoring your code

Jasper van Heijst, on 17-09-2019
Category: Blog, Architecture, Development Tags: Software Refactor

It’s common sense of course to keep your codebase clean all the time, but this isn’t always the case. It simply happens that a codebase grows in ways that were not foreseen on forehand resulting in an unclear architecture or dirty code (that must be the opposite of clean code). In this article I’d like to share our experience in dealing with such a situation, why we needed to refactor, what we did and how it improved our codebase. Why you need to refactor Modern software engineering is an agile…

TL;DR: this article discusses in detail my presentation at Spaces Summit 2018. I talked about the need to stop smashing our keyboards and “blindly” focus on “high-speed”, and start thinking about what we are doing, why and how we are doing it.

Web applications usually start small and loveable, but gradually become larger and larger as more people work on them and front-end technologies move on. If you’re not careful they can potentially end up as the one thing no-one wants to touch anymore and cause a lot of frustrations for agile teams and business innovators alike.

According to figures from Ingenico, around 15% of site visitors in the Netherlands that begin the payment process do not complete their transaction. This can have many causes which will be examined later in this article.

“My past year as a software engineer at bol.com has mostly been dedicated to breaking down one of the big monoliths within our software landscape into smaller services. To be more specific: I’ve been working in a team to extract the processes related to customer returns into a separate microservice.”
