Hey there! πŸ‘‹ I'm Katheu :)

Psychologist & Software Engineer

I'm a psychologist turned software engineer who enjoys understanding complex problems and building technology that makes them simpler. My work sits at the intersection of people, technology, and problem-solving. I spend my time on backend systems and APIs, AI-powered applications, and tools that turn data into useful decisions.


🧠 HOW I THINK

Psychology taught me to ask: Why do people behave this way?

Engineering taught me to ask: How can we build something that works?

AI makes me ask: What becomes possible when we combine the two?

I'm drawn to problems where the technical solution is only one part of the equation. The harder part is understanding the people using it.


βš™οΈ WHAT I BUILD

Backend Systems

APIs, business logic, authentication, databases, integrations and reliable services that scale.

AI-Powered Applications

LLM applications, RAG systems, intelligent assistants, AI agents and practical AI that solves real problems.

Data & Automation

Data pipelines, ETL processes, forecasting models and systems that turn data into actionable insights.

Cloud & Infrastructure

Deploying, containerizing and operating applications in production. I care about reliability, observability, and maintainability.

Human-Centered Technology

Products where understanding the people using them matters just as much as the technology behind them.

πŸš€ FEATURED PROJECTS

MindConnect

A mental-health platform designed around the needs of young people in Kenya. This project emerged from conversations about how technology can support mental wellbeing in contexts where resources are limited.

MoodForecast AI

An AI application exploring the relationship between environmental conditions and mood. This project sits squarely at the intersection of psychology and engineering: using weather data and machine learning to understand how context shapes wellbeing.

🧩 ENGINEERING PHILOSOPHY

I care about more than getting code to run.

I care about understanding the problem before solving it. Building systems that are maintainable, not just functional. Designing around real users and real constraints. Making complex systems understandable. Learning the why, not just the how. Using technology where it creates meaningful value.

Code is communication. It should tell a story.


πŸ”¬ WHERE PSYCHOLOGY MEETS ENGINEERING

My background in psychology directly influences how I approach software.

It makes me naturally curious about human behaviour, decision-making, user experience, systems thinking, communication, and learning. I'm especially interested in how people interact with AI.

I don't see psychology and engineering as separate. One helps me understand the people. The other helps me build for them.


πŸ“š CURRENTLY EXPLORING

AI agents and agentic systems. Backend architecture at scale. Distributed systems. Deeper work with LLMs and prompt engineering. Cloud infrastructure and DevOps. Data-driven products. The emerging field of human-AI interaction.

I'm experimenting with Ruby and other languages to understand how different design philosophies approach the same problems. There's something valuable in learning across different ecosystems.


🌱 BEYOND THE CODE

When I'm not building software, you'll find me writing poetry, playing piano, drawing, playing basketball, thinking about psychology, or distracted by cats.


🀝 LET'S BUILD SOMETHING

I'm interested in working with people who are building interesting things, solving meaningful problems, and asking difficult questions.

If that sounds like you, let's talk. You're already on my GitHub, so now you know me. Feel free to get me to know you.
