Highlights
Nairobi County Hackathon
Winners • $1000 Cash Prize
Track Record
Power Hacks Hackathon - 4th Runners-Up
October 2024 • First Hackathon Experience
SOSTOS Blog is a platform to verify public statements and combat misinformation. I participated in my first hackathon representing SOSTOS Blog, sponsored by Safaricom and SpaceYaTech. As second project lead, I helped develop the platform, coordinate the team, and pitch our solution.
Our project earned 4th Runners-Up, giving me hands-on experience in full-stack development, rapid prototyping, teamwork, and presenting innovative solutions.
Key Outcomes:
- • Built a platform to verify public statements
- • Coordinated team and supported pitching
- • Secured 4th Runners-Up in a major hackathon
- • Gained practical experience in full-stack development and teamwork
MOMENTS FROM MY JOURNEY
Blockchain & Web3 Bootcamp
April 2025 • Blockchain Hackathon win
I participated in an intense 4-day Blockchain & Web3 Bootcamp, where we were introduced to cutting-edge technology and trained on leveraging blockchain to design innovative solutions for real-world problems. On the second day, I led a team of 4 to brainstorm and pitch a project aimed at helping the Nairobi County Government implement a startup-level environmental solution called the Go Green Initiative.
Our pitch was selected among the top 5 team ideas, and we were given two weeks to develop a fully functional system. I coordinated the team's tasks, designed the smart contract layer, and ensured the platform architecture was robust and scalable.
On the day of the hackathon presentation, our project BebaPay won $1,000 in cash, earned collaborations, and opened a broad path for my career in technology. BebaPay is a tokenized recycling platform that incentivizes residents to recycle by rewarding them with digital tokens, which can be redeemed for goods or services. It aims to reduce waste and promote sustainability through decentralized, transparent transactions.
After the bootcamp, we refined BebaPay and presented it to the Nairobi County Government, showcasing it as a startup-ready solution for their environmental initiatives. The Go Green Initiative integrates technology, community engagement, and blockchain-based incentives to create measurable environmental impact while fostering entrepreneurship and innovation.
Key Outcomes:
- • Led a team of 4 to design and build a full-functioning blockchain platform
- • Winner of $1,000 cash prize at the hackathon
- • Developed the Go Green Initiative for Nairobi County Government
- • Created a tokenized recycling platform to incentivize sustainable behavior
- • Gained collaborations, mentorship, and exposure to advanced blockchain technologies
