Interviewing is a very important skill to have as a developer. We need to actively practice for improving our interviewing skills as developers. The way to develop interviewing skills is not just solving questions on Leetcode and calling it a day. Interviewers care about how you communicate, what kind of clarifying questions you ask and the way you break down the problem just as much if not more than your coding skills. So mock interviews are the best way to work that interviewing muscle to improve your confidence while also communicating your solution under time pressure. I use https://www.tryexponent.com/practice for conducting mock interviews with random people around the world every weekend. I noticed that Indians are the most active on the platform and I realized why they are getting much more opportunities in the international job market compared to any other country. I have conducted 9 mock interviews on the platform as of yet and 8 of them were with Indians. If we want to get great opportunities in the international job market, being able to do the job is not enough. We first need to get our feet in the door. After all, we can't do the job, if we are not offered the job right?😁 Let's focus on skills that get us the job just as much us the skills that allow us to be useful once we get the job.

​Let’s take a painful trip down memory lane ​The year is 2016. I just graduated. My first fulltime salary? 5,400 ETB. back then, with the rate at 22 ETB/USD, that was a respectable $245 ​But wait ... the dollar hasn't been sleeping either. Thanks to US inflation, that $245 in 2016 is worth about $330 today ​If we take that inflation-adjusted $330 and convert it at today’s CBE rate of 154 ETB, do you know what we get? ​💥 50,000 ETB. 💥 ​The Conclusion: To live the exact same lifestyle you had with 5,400 birr in 2016, you need to be earning 50,000 birr in 2026 ​Let that sink in

Don’t let the gatekeepers slow your momentum When someone looks down on you for using frameworks, open source code, or AI agents, remember that true innovation isn't about doing it the hard way — it's about how far you go with the tools you have. As Carl Sagan famously said:

"If you wish to make an apple pie from scratch, you must first invent the universe."

Unless you’re hand-soldering your own CPU and writing your own binary, we’re all standing on the shoulders of giants. Don’t get stuck in the "from scratch" trap. Use the tools. Leverage the tech. Ship the product 🚀

🔄 Event Update

🚀 GDG AAU Open Lectures: Session #01 Just a quick update from us — big thanks to our guest speaker Abenezer Alebachew for kicking off our very first open lecture session 🙌 On Monday, Dec 22, we hosted Session #01, where the focus was on Clean Architecture and Domain-Driven Design. It was a relaxed session that introduced how these ideas help developers organize codebases in a clean, scalable, and maintainable way.

✨ Key Highlights: - What Clean Architecture is and why it matters - Basics of Domain-Driven Design - How these concepts apply to real-world projects - Open discussion and Q&A with the audience

📢 Stay in the loop If you want access to resources from the session and updates on upcoming open lectures, make sure to 👉🏼 JOIN THIS GROUP And Huge Thank You for everyone who was part of this session, we really hope to see you again, make sure to join the group to get access to all the resources.

For anyone who wants resources from the Clean Architecture lecture I gave, the GDG team has posted them in their group. It was a great session and I want to thank the GDG AAU team and all who were there for making it possible

🚀 GDG AAU Open Lectures: Session #01

Is your codebase working against you ❓

We’ve all been there: a project starts off great, but as it grows, it becomes a "spaghetti" mess. You change one line of code, and three unrelated things break. Suddenly, adding a simple feature takes weeks because the logic is tangled with the database and the UI. Join us for the very first GDG AAU #OpenLectures—a new series of deep-dive technical sessions designed to bridge the gap between academic theory and industry practice. Topic: #CleanArchitecture & DDD Speaker: Abenezer Alebachew (Senior CS, AAU) Key Highlights: 📌 The Problem: Why codebases rot and how architecture stops it. 📌 Core Concepts: DDD, Layering, and Dependency Inversion. 📌 Python Pro-Tip: Using Protocols for Go-style implicit interfaces. 📌 Practicality: Real backend examples and knowing when to keep it simple. 📍 Venue: 5Kilo Campus NB 107 📅 Date: Dec 22, 2025 G.C 🕒 Time: 11:00 LT Register Now: https://forms.gle/CqwZb4dbbr9HyidFA

I will be speaking on Clean Architecture & DDD on Monday at GDG AAU. If any of you guys are interested in the topic, you can join.

The slide says this, but the school still choose to give us the course 😑 @cyber_Guardian5

Real

In my current job, I am mostly refactoring previously written code to follow DDD (Domain Driven Design) principles. If any of you are experienced with DDD or Clean Architecture, you would know how much Interfaces are used for dependency inversion. This can usually be implemented in languages that support interfaces very easily. You define the interface you want in the domain layer, and you extend that interface and implement it in any of the layers that the domain should never depend on. But in Python, you don't have access to interfaces. So what I found out recently is the concept of Protocols in Python. Protocols allow you to define contracts that can be implicitly implemented by your layers. It works exactly like interfaces in Go. You don't have to explicitly inherit from or extend the protocol. As long as you implement all the methods defined in it, it just works. I hope this will be useful for anyone who is working on DDD with Python.

This is just a meme but eventhough programmers in rich countries get paid more than average salaries, they are usually in the middle class - upper middle class range in their countries. The cost of living is also very high in places where big tech companies are located making them spend more than people living in areas where the cost of living is lower. Meanwhile programmers in poor countries usually earn an amount of money small - medium sized business owners earn in their countries when they are employed at companies located in the rich countries remotely, which places them among the highest earners in their countries. Wealth is just relative and whenever salaries are considered, cost of living in the area should also be considered. When saying this, I'm not denying the fact that there are benefits that come with residing in the developed countries such as reliable electricity, reliable internet access and better systems and infrastructures. I'm just saying that everything is a tradeoff and there is no perfect scenario

I just solved today's Advent of Code challenge. The second part took me a lot of time. Been staring and writing out the pattern on excalidraw for so long. My solutions are in my repo: https://github.com/abeni-al7/advent_of_code

I am switching my main backend language from Python to Go. Since it has been a while since I touched Go, I decided to refresh my memory of its syntax by building a wc clone from John Crickett's https://codingchallenges.fyi/. I built the line, word, byte, and character count functionalities and wrote unittests using testify. I have also included the architecture documentation and an easy-to-follow Readme. Here is my repo: https://github.com/abeni-al7/aben-wc I would appreciate any feedback on my code and suggestions for improvement. LinkedIn X
