About us

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.

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 Golang apps, you can add your own to it:
- https://github.com/air-verse/air
- https://github.com/christianselig/apollo-backend
- https://github.com/miniflux/v2
- https://github.com/golang/pkgsite
- https://github.com/benbjohnson/wtf
- https://github.com/discourse/discourse
- https://github.com/bevane/repocheck
- https://github.com/saravanasai/goqueue
- https://github.com/golang/groupcache
- https://github.com/olric-data/olric
- https://github.com/hashicorp/memberlist
- https://github.com/dgryski/go-shardedkv/tree/master
- https://github.com/dgraph-io/ristretto
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.

[Golang & Java] free agentic coding workshop
Sun, May 10 · 11:00 AM CEST
AES, Albert-Einstein-Straße 14, Berlin, DE
Join us for a hands-on, collaborative 4-hour workshop where we use LLMs to code. We will be implementing the following 3 exercises: connect four amazon locker and elevator

### What we will do

We will use the LLM (any free one, like chatGPT) to write code that solves a given problem. Our goal is to not write code by hand, and to produce an application that passes a set of specifications.

### 🛠 Share ideas about agentic coding

We will be practicing our agentic coding skills:
- bring a laptop with Java or Golang installed
- know how to code in either Java or Golang
- share and explore ideas about how to use LLMs to create production-ready applications
### 💬 Atmosphere & Logistics

The workshop is free. There will also be a 20 min pause, if you want to order snacks.
