My Story

The Journey So Far

Not just a résumé — a narrative of curiosity, grit, and continuous growth from Nairobi to Paris and beyond.

Aug 2024 — Present Nairobi, Kenya

🚀

The Full-Time Leap

Software Engineer · Vitafluence.ai

Stepped into a full-time role developing AI-powered agents for Lakesai with Python, Django, and LangChain, building a Windows desktop extraction tool for Neurobee data, and training a gaze-tracker ML model with OpenCV and Random Forest. Resolved a critical GCP outage by setting up a temporary AWS server to keep traffic flowing, and deployed scalable apps with Python and React Native.

🎖️

AI Campus Certificate

Certificate of Achievement · AI Campus — The Learning Platform for Artificial Intelligence

Deepened expertise in AI technologies and machine learning through AI Campus, sharpening the skills behind the agents and models I build in production today.

Aug–Oct 2024 Nairobi, Kenya

🏆

Africa to Silicon Valley

Certificate of Recognition · A2SV (Africa to Silicon Valley)

Earned recognition through A2SV's program, sharpening problem-solving and technical skills as part of a network built to connect African engineering talent with global opportunity.

May–Jul 2024 Frankfurt, Germany

✈️

The Internship That Took Me to Europe

Software Engineer Intern · Vitafluence.ai

Based in Frankfurt, I built a teaching-assistant AI agent for Lakesai (with an internal mobile app version), shipped Notion-style AI note-taking, and fixed a critical bug to let users stop generative AI responses mid-stream. Built and deployed Xaidi end-to-end — React Native apps, Django/Node.js backends, and AI models — live on Google Play, TestFlight, and AWS, then added multi-agent support. Represented Vitafluence.ai at VivaTech 2024 in Paris, showcasing Xaidi and emotion-recognition AI models.

May 2020 — Aug 2024 Nairobi, Kenya

🎓

The Degree

B.Sc. Applied Computer Technology · USIU-Africa

Graduated Cum Laude with a 3.621 GPA in Computer Software Engineering — building the theoretical bedrock in software design, systems, and engineering principles that underpins every real-world problem I'd later solve.
