After a full week of intensive Bitcoin programming training, the developers at Zone01 Kisumu moved into the most exciting phase of the bootcamp: building real-world solutions powered by Bitcoin, the Lightning Network, and LND.
One thing I learned throughout the experience is that the human mind is truly fascinating. The room was filled with innovative ideas, each attempting to solve a different problem. As the saying goes, no idea is a bad idea—every concept had the potential to make an impact.
A total of 17 teams were formed, and each team embarked on a 24-hour hackathon journey to transform their ideas into working products. After an intense day of development came the presentation phase, where we had the privilege of showcasing what we had built.
Our team developed Kasi, a WhatsApp chatbot that enables Bitcoin transactions directly through WhatsApp. The goal was to make Bitcoin payments more accessible by leveraging a platform that millions of people already use daily.
To build Kasi, we integrated the Twilio API for WhatsApp communication and utilized the Bitnob platform to facilitate Bitcoin transactions. Python was used throughout the development process. The project was brought to life by six developers: Claire, Lamka, Ijay, Dishon, Talo, and myself.
Beyond the technical implementation, the hackathon strengthened our understanding of collaborative software development. We practiced Git workflows, team coordination, version control, task management, and effective communication under tight deadlines—skills that are just as valuable as writing code.
Although we did not finish at the top of the leaderboard, the experience was incredibly rewarding. Every team brought something unique to the table, and the winners fully deserved their recognition. Congratulations to all the teams that participated and showcased their creativity, determination, and technical skills.
One moment from the presentation will stay with me for a long time. As we were demonstrating Kasi to the judges, the free Twilio trial credits we had been relying on ran out. Imagine the panic. One moment the demo was working, and the next we were standing in front of the judges trying to explain and maneuver around an issue we never expected to happen at that exact moment.
It was painful, frustrating, and almost comical at the same time. But that's the reality of software development—sometimes the biggest lessons come from things that fail when you least expect them to. It's a lesson our team will never forget.
Developer tip: Always double-check your free-tier limits, API quotas, and trial credits before a live presentation. Trust me on this one.
This bootcamp and hackathon reinforced my passion for technology and problem-solving. It reminded me that innovation begins with an idea, but impact comes from taking that idea and turning it into something real.
I hope that one day, through the ideas I develop and the technical skills I continue to build, I will create solutions that make a meaningful difference in people's lives.
⚡ Build. Learn. Collaborate. Improve. Repeat.
