What we’re about

Welcome to Berlin Software Design — a community for engineers and architects who want to sharpen their software design and architecture skills through practice, discussion, and collaboration.

We focus on learning by doing: software architecture katas, design challenges, system walkthroughs, and peer feedback sessions. Each meetup is a chance to tackle real-world design problems, share approaches, and improve how we think and communicate about architecture.

Whether you're an experienced architect or a developer curious about system design, join us to grow your skills, exchange ideas, and connect with like-minded tech professionals in Berlin.

[Pair Programming] Leetcode Grinding Session
Online
We take turns, one member acts as the coder sharing their screen while the rest of us guide the solution.

We use Codewars.com instead of Leetcode. Codewars is perfect for this format — after solving a kata, you can explore community-ranked solutions, seeing how others approached the same problem.

#### What to expect:
- We will solve several Codewars problems together
- Each coder takes a turn while the group collaborates
- After each problem, we review top community solutions and discuss what we learned
#### What you’ll need:
- A Codewars account (free)
- A stable internet connection
- Willingness to engage, discuss, and share insights
#### All skill levels welcome!

No matter your experience level, this is a supportive space to grow your algorithmic thinking and learn from others’ perspectives.

[pair programming] code review random Java git repositories
Online
We read small github repositories, and try to understand the code and what design decisions were behind it.

Here is a list of such small Java apps, you can add your own to it:
- https://gitlab.com/burak-dev/url-shortener
- https://github.com/harismuneer/Library-Management-System-JAVA
- https://github.com/ebarlas/microhttp
- https://github.com/bowbahdoe/json
- https://github.com/bowbahdoe/regex-router
- https://github.com/joel-jeremy/externalized-properties
- https://github.com/joel-jeremy/deezpatch

Together, we’ll:

Read and understand the code

Discuss the architectural decisions/its design

Write some Architecture Decision Records (ADRs)

Draw a class diagram and a C4 diargram

Decide what testing strategy the repo should have

Discuss pros and cons of the current implementation

It’s a great way to sharpen your architecture skills and see how others design and structure their systems.

No prep needed — just bring your curiosity and your intuition.

[face to face] Interview Simulation
Strandbad Mitte, Kleine Hamburger Straße 16, 10117 Berlin, Berlin, DE
Join this Interview Simulation session — to sharpen the skills for both interviews and architectural pitches.

💡 How it works
The event is split into three parts:

Most common behavioral & HR questions - you will receive a printed list of behavioral/HR questions and we brainstorm tips on how to prepare for them

Interview Simulation (10 minute rounds) – One participant acts as the interviewee and answers a round of behavioral and design-focused questions. Each other participant gets to ask him one interview question.

Feedback Round – The group provides feedback on communication, structure, and clarity. Constructive criticism is encouraged.

💡You will be asked:

Behavioral questions (“Tell me about yourself”, “Describe a challenge you faced...”)

Technical questions (based on your tech stack)

Light design problems (high-level reasoning, not code)

No need to prepare anything in advance — just bring curiosity and an open mind.

Feel free to bring your CV if you’d like feedback from others, or share a few words if you’re currently job hunting. If so, we will also brainstorm answers to more common questions that you were asked.

Whether you’re preparing for an interview or simply want to grow as a software designer or architect, this session is for you.
