Despite all its “sticks and stones”, 2020 had a significant impact on entrepreneurship. With cross-industry shifts towards digitalization, it was a year of “think different and respond fast.” In a Fireside Chat at an online Thursday Gathering event by Venture Café Warsaw, Sylvestre Lucia, co-founder and CEO of thirty3, reflects on some of the major changes in the sector, and points out unintended silver linings and emerging trends to observe in 2021.

Connect, Negotiate, Act

I think there were two ways businesses have approached challenges in 2020. One was to say “ok” and go along with it, continue working on what one has…

The idea for the article came to my mind a long time ago, when I was already working remotely, before the COVID era. Since then I am often questioning myself — what is the ideal remote setup (also recently I’ve started to get more and more of those questions from my family members and friends)? And I’ve realized that to properly answer this question — I need to analyze it on multiple dimensions. In the last 18 months, I’ve been leading the organization which one of the most important principles was remote first organization. On top of that, I’ve been…

A comprehensive guide on how migrations with django-tentants work and what we should keep eye on.

Usually, we don’t pay much attention to migrating things in Django. As long as we keep everything simple, running makemigrations and migrate commands are more than enough. Sometimes things get a little more complicated and we, developers, need to help the Django do its job. It is usually done with RunPython operation that allows running some Python code within the migration. While it is pretty straightforward for standard Django migrations, things get more complicated when we use multitenant architecture provided by the django-tenants package.

So here, I will dive into django-tenants migrations — describe how they work, and inspect the…

Thank you, Marta, for the illustration.

Understanding/using multi-tenant architecture in Django from the perspective of my protegee, our new teammate, a junior engineer at thirty3 — Dominik. Without further ado, I’ll let him do the writing.

Junior Introduction

Hello there! My name is Dominik, I am a junior developer at thirty3, recruit among a bunch of professionals.

An environment that’ll be challenging, but is probably the best one for a beginner like me to be in. Place where there’s a mentor which can help me in tough times, answer all my questions and point the way, tell me about mistakes I make.

Does it make learning programming easier…

You can read this post on my blog too —

Recently I started thinking about changing my blogging engine and the template that it used. It felt a bit too bloated for my tastes, outdated and messy. After a couple of months of waiting, I’ve finally spun into action to create braindead — a braindead simple static site generator with markdown and code highlighting support.

The first thing that I did was to look through available solutions for blogs, blogging engines and free templates. I had experience with Pelican and Jekyll. Both were quite okay, yet felt like they’re…

A time has come in which I have to write a very tough article. Today I’m going to ponder a bit about failure.

My failure to be exact. I think it’s a rare topic in this day and age, where everyone and everything is perfect, life is `sculpted` to fit a certain image and you are only allowed to be a `winner`.

For now, I still have no clue where I’ll publish it, maybe nowhere, maybe only on my blog, or maybe on the company’s medium.

It’s more of a way of sorting stuff out for me rather than something…

Recently I had the opportunity to facilitate a retrospective for the first time in my life, this will be my summary of the experience.

The idea began with one of our founders asking me if I’d like to do that.

Me? Agile/scrum-slavery/whatever-sceptic, leading a retrospective? Sounds like a recipe for a disaster.

Well, I agreed immediately. Despite the fact that for the most part, I’m not a huge fan of all the current buzz around agile, scrum slaves (I love this term and abuse it often) and so on, plus the only pleasant thing that comes to my mind when…

I am in the IT industry for quite a long time and somewhere on the line, the idea emerges that full-stacks do not exist — and I was always really skeptical about this idea. I believe I have plenty of arguments to defend this hypothesis. Of course, this will be my personal opinion on the topic, but with a solid background and maybe with a bit of luck this article will trigger some discussion and will help me to understand the other side — which will be: Full-stacks actually do exist.

What does it mean to be full-stack?

First of all, we should start with a definition…



Curious title, right? I mean who does that these days? Adhere to eXtreme Programming principles at work, do it in a remote and asynchronous way. And in a distributed manner. On top of that, hire juniors that are not always that fit for such type of work. Sounds like recipe for a disaster? Wrong.

Well, we do that. This article is my own take on how that works for us and especially, for me. I’ll write not only about work, but also life.

And my personal development, my growth as a person, what changed compared to my earlier jobs.
