View projectIsikole
Actively developedSchool management, built for Africa.
Founder · Product · Engineering
I built Isikole to simplify how schools manage academics, attendance, finance, communication and operations in one unified platform.
- 01
Problem
Schools shouldn't need five different systems to run their day.
- 02
Product
A unified platform for academics, attendance, finance and communication.
- 03
Architecture
Modular backend services designed to evolve with the school.
- 04
Engineering
Modern stack, clean code and scalable APIs with strong engineering practices.
- 05
Infrastructure
Cloud hosting, automated deployments and built-in observability.
- 06
Shipped
Isikole is live and actively being developed.
Built from a real problem.
Shipped as a real product.
Engineering
I care about what happens
behind the interface.
From APIs and distributed systems to cloud infrastructure and AI-powered workflows, I build software designed to work beyond the demo.

How I build
- 01
Start with the problem
I don't start with a framework. I start by understanding the workflow, constraints and people using the system.
- 02
Design for production
Architecture should account for reliability, security, observability and scale from the beginning.
- 03
Keep complexity behind the interface
The best systems make complex workflows feel simple to the people using them.
- 04
Ship. Measure. Improve.
Production feedback is part of engineering.

Walter Ruganzu
Engineer · Builder · Founder
I'm a software engineer and founder focused on building production software around real-world problems.
My work has taken me across healthcare, fintech, education, enterprise systems and AI, from backend infrastructure and distributed services to products used by real organizations.
Today, I'm especially interested in the space where engineering meets product: finding a problem, understanding it deeply, and building the simplest system that can solve it well.
Building my own products
Isikole started from a simple observation: schools need better tools to manage the complexity behind education.
I build it end to end, across product, backend, frontend, infrastructure and deployment.

Isikole
School management, built for Africa.
What I care about
- 01
Simplicity
Complex systems should feel simple to the people using them.
- 02
Ownership
I like understanding a product from the problem all the way to production.
- 03
Craft
Good software is not only correct. It should be thoughtful, maintainable and reliable.
- 04
Impact
The best systems solve problems that matter outside the codebase.
Beyond the code
Outside of engineering, I enjoy learning, creating, exploring ideas and finding new ways to turn things that seem complicated into something useful.
Still learning. Still building.
WritingWriting
Things I've learned
building software.
Notes on systems, production software and the space where engineering meets product.
In progress
I'm writing about the things I keep running into while building production software. The first pieces are on the way.
- 01SystemsWhy architectures hold up, and where they quietly don't.
- 02ProductionWhat running software in the real world teaches you.
- 03ProductTurning a problem worth solving into something people use.
More soon.
Let's build
Have a problem worth solving?
Let's build something
useful.
I'm open to interesting products, engineering problems, and opportunities to build things that matter.
