YaBudu — Making Event Registration Effortless

Organizing small group events might sound simple — until you’ve tried doing it through a group chat. Whether it’s a local tennis club, a study circle, or a table-tennis group, coordinating who’s coming can quickly turn into a flurry of messages, crossed wires, and last-minute confusion.

That’s the everyday problem I set out to solve with YaBudu — a modern web app that simplifies how people register for upcoming events in shared spaces.

From chaos to clarity

In places like table-tennis clubs, where the number of available tables is limited, having ten people sign up for eight spots is more than a minor inconvenience — it’s a scheduling headache. Traditional messaging tools like WhatsApp or Telegram aren’t designed to manage such constraints.

Yabudu replaces those scattered messages with a clear, structured interface. Participants can see all upcoming events, register with one click, check who’s already signed up, and instantly know if a session is full. No confusion, no overbooking — just clarity and fairness.

A story of iteration and growth

This isn’t my first time tackling this kind of problem. Eight years ago, while mentoring students at Novosibirsk State University (NSU), I built a similar app in Golang. Back then, the goal was to help coordinate student projects and events more efficiently.

That early version taught me the importance of simplicity and reliability. Yabudu is its modern successor — rebuilt from the ground up using Next.js, and designed to demonstrate not only how far web technology has come, but also how much I’ve grown as a full-stack engineer.

Beyond code — a showcase of craftsmanship

YaBudu highlights my ability to take a real-world coordination problem, design a user-friendly solution, and implement it end-to-end. It brings together everything I value in software engineering:

Empathy for users, by solving a tangible pain point
Clean, scalable design, ensuring every interaction feels intuitive
Ownership from concept to deployment, demonstrating independence and accountability

Why it matters

While YaBudu may seem like a small app, it reflects a larger philosophy — that technology should make human coordination smoother and more transparent. It’s a simple idea brought to life through thoughtful design and technical precision.

For me, YaBudu isn’t just a side project. It’s a reflection of how I approach problems: observe, simplify, and build something that just works.

Would you like me to tailor this further for LinkedIn publication (with a strong opening hook, shorter paragraphs, and a closing call-to-action about your skills or availability)? That version tends to perform best when HR or hiring managers are the primary audience.
