QuinQueでの冬季インターンは、自分にとって初めての仕事経験でした。しかも日本企業で、しかも国際的なチーム。正直かなりワクワクしていましたし、同時に少し緊張もしていました。でも振り返ると、最初から最後まで本当に濃い経験でした。
インターン前の話
きっかけはTalendyで見つけた求人です。会社のミッションや取り組みを調べるうちに、「ここで働いてみたい」と素直に思えたのが応募の理由でした。面接はシンプルで、スキルだけでなく意欲もちゃんと見てもらえた印象です。5日ほどで合格の連絡をもらったときは、「ついに来たか」と感じました。
スタートしてみて
2025年12月1日にスタートし、会社やチーム、プロジェクトの説明を受けました。最初は「自分にできるのか？」と不安もありましたが、チームがとてもフレンドリーで、すぐにその不安は消えました。質問もしやすくて、すごく助けられました。
プロジェクト内容
取り組んだのは、社員のレポートやデータを効率よく管理するための「QApps」というアプリ開発。日々の進捗を記録しつつ、企業側も全体を把握できる仕組みです。
技術的には、Next.js、ShadCN UI、MySQL、Dockerなどを使って開発しました。最初は小さなタスク中心でしたが、徐々に全体構造も理解できるようになり、特にDockerによる環境分離の考え方は大きな学びでした。
苦労したこと・学び
もちろん失敗もたくさんありました。実装がうまくいかないことも多かったですが、チームは責めるのではなく、ちゃんと時間をかけて教えてくれました。
一番印象に残っているのは、AIに頼りすぎてしまったことです。スピードは上がったものの、コードの質やセキュリティに問題が出てしまい、メンターに指摘されました。この経験から、「ツールはあくまで補助で、責任は自分にある」という大事なことを学びました。
まとめ
このインターンは、ちょうどいい難易度とペースで成長できる環境でした。無理なく挑戦できたのが大きかったですし、チームが自分の意見もちゃんと聞いてくれたのも嬉しかったです。インターンでも「プロジェクトの一員」として扱ってもらえたのは、とても貴重な経験でした。
ITの世界は広くて不安になることもありますが、このチームと一緒に働いていると、ちゃんと前に進めている感覚がありました。安心して挑戦できる、そんな環境でした。

Winter Internship at QuinQue
Winter internship at QuinQue, marked my very first professional experience, let alone working with a Japan-based company. The excitement of stepping into a real-world development environment, combined with the opportunity to collaborate in an international setting, made this experience truly special from the very beginning.
Before the Internship
My journey actually began well before December, when I came across an opening on the Talendy portal. I explored the company’s profile, its mission, and its objectives. I found myself resonating with the work QuinQue was doing, which motivated me to apply.
The interview process was straightforward yet meaningful, it focused on my resume and, more importantly, my motivation for joining the company. About five days later, I received the results, and fortunately, I was given the opportunity to join QuinQue. That moment felt like a significant milestone.
Starting Out
The internship officially began on December 1st with an introduction to the company, the team, and the project I would be working on. As a relatively inexperienced student, I initially felt nervous about meeting expectations in a professional environment. However, the anxiety quickly faded as I interacted with the team, everyone was incredibly kind, approachable, and supportive.
The Project and My Role
The problem statement focused on developing a modern solution to help companies manage and organize employees’ reports and related data more efficiently.The proposed solution was QApps – a Morning Management App, designed to provide a centralized platform where employees could log their daily progress while enabling companies to efficiently manage resources and monitor activities.
The virtual meet discussion helped me understand both the functional requirements of the application and the technical approach. The project involved setting up a Next.js environment, using the ShadCN UI library for the interface, MySQL for managing large volumes of structured data, and Docker for containerization to ensure a consistent and scalable development setup.
In the beginning, my responsibilities focused on resolving assigned issues and working on smaller features. This helped me gradually become comfortable with tools like Git, AI-assisted development, and basic Docker concepts. Over time, I was getting a better picture about how the project should look and gained a better understanding on some technical topics like how containers help structure applications by isolating different services and maintaining consistent environments.
Challenges, Mistakes, and Learning
There were many instances where I implemented features incorrectly or below expectations. However, what stood out was the team’s patience. Instead of criticism, I was given time and guidance to improve my understanding. That environment made a huge difference.
At one point, I became overly reliant on AI tools to speed up my work. While it helped me move faster, it also led to poorly structured and sometimes insecure code, something I didn’t fully realize until my mentor mentioned. It was an embarrassing moment, but also a turning point. It taught me to be more mindful and responsible in how I use such tools. It helped me understand not just how to build software, but how to grow as a developer
Final Thoughts
Looking back, this internship felt like the perfect learning environment for me. One of the biggest reasons was the pace, it was challenging enough to push me, but not overwhelming to the point of burnout. This balance helped me stay motivated and genuinely enjoy the learning process. Another important factor was the team’s openness to listening to my ideas and giving me a sense of ownership over parts of the project. This made me feel responsible and involved, even as an intern, an experience that is not always common in larger organizations.
Being in tech often feels like standing in front of an ocean of unknowns. But working with a supportive team felt like being on a stable ship, guided, safe, and constantly moving forward.
