    Category: Blog, Culture

    I, Asparuh Hristov, a Data Science Craft Lead at bol.com, believe that my working experience actually helps my other huge passion: Climbing. Sure, my work leaves a limited amount of time for actual climbing, but at the same time improved the quality of this time spent practicing my hobby tremendously. During the Spaces Summit 2020 digital conference from bol.com, I did a talk on “How to work the climbing ladder?”. About the talk “Your job should be your passion” has been repeatedly questioned by work/life-balance “gurus” with the argument that…

    Spaces Talk #2: Introduction to Sociotechnical Architecture

    Category: Architecture, Development

    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…

    Or: Everybody is a remote UX Researcher   In our previous post we talked about how ‘Everybody is a UX Researcher’ and we believe that involving all stakeholders and letting them talk to our users is vital for a good product development.  Then corona happened, but we wouldn’t let a global pandemic bring us down.

Limited resources give you an opportunity to be creative.    Remote Usability research  We love to geting our user’s feedback; with a quick guerrilla test, full scale usability test,…

But we found out there’s an even more important step before. It’s getting the answer to the question “what are we going to do?” Many people and organisations who are organizing conferences, meetups, summits…

    Category: Development

    We can imagine that at a regular company your colleagues might become very nervous when you worsen the frontend performance by more than a second on the onload, just before the peak season. In this story we’d like to share our journey from experiencing a setback in performance that was caused by us innovating, to the point where we became the retailer with the second fastest frontend response times (Twinkle and Computest benchmark study) in the Netherlands. Before diving into the details, it’s worth mentioning that we as software engineers…
