A New Chapter: Software Engineering at Colorkrew

Self-Introduction: Nice to meet you. I'm Mochizuki from Colorkrew. I'm currently in my second year as a working adult, and after changing jobs once, I work as a cloud engineer at Colorkrew.

I’m Atharva, a sophomore studying Media Sciences and Engineering at the University of Tsukuba under a full MEXT scholarship. I joined Colorkrew as a SaaS Software Engineering Intern in February 2026.…
Introduction: Hello. I'm Yano, who joined as an infrastructure engineer as a new graduate in April. Time flies—it's been three months since I joined the company. Although I only started three months after joining, I started interning in November 2024, so it has been 1 year and 8 months since I started working at Colorkrew. Even I was surprised at how long it was. This time, I plan to focus on things that changed during my internship and after joining. …

I’ve been a junior developer at Colorkrew for over a year now. For a long time, I resisted integrating AI into my workflow, aside from the occasional browser search. My reasoning was simple: AI felt 'dumb.' It made bizarre mistakes and felt intrusive. If you’ve ever enabled Copilot only to have its tab-completions derail your train of thought, you know what I mean. I valued my own intuition over a tool that seemed to prioritize saving keystrokes over actual logic.
Introduction I'm from Romania, and for almost half my life I've been studying and investing most of my time into programming. I joined Colorkrew 6 months ago as a junior software engineer — this is…

Happy New Year everyone! Last year was also a really turbulent year. In the world, there is no end to conflict, inflation continues, and AI-driven transformation is approaching us at a speed beyond our imagination. Looking back, 2025 was not a year of "completely new things" happening, but rather a year in which the evolution of AI, the heating of the global economy, and the continuation of conflicts that have continued over the past few years have accelerated at once. ...

Employment as a new graduate. For many people, it is one of the most important life events in their lives. Over the past 30 years, countries around the world have accelerated their economic ties and globalized. On the other hand, politically, the conflict between liberal capitalism, the former communist countries, and the expansion of the presence of the Global South have changed from the relatively stable international situation in the second half of the 20th century to the era of the VUCA, which is unstable and has no future. ...
Happy New Year! At the end of the year, I watched Slam Dunk. This is the one I'm doing in the movie theater now. THE FIRST SLAMDUNK \*No spoilers. Don't worry, Slam Dunk was a manga after I became a member of society, but I also loved the original. If I had been a student and was doing club activities, I think the level of emotional empathy would have been even different. ...
