About

Hi, I am Isaiah Nyalali — engineer, builder, and strategic technology leader based in Tanzania.

Full Stack Developer
Wireless Engineer
Fractional CTO

I operate at the intersection of Software Engineering and Wireless Telecommunications, dedicated to engineering high-impact technical solutions. With a BSc in Business Information Technology from the University of Dar es Salaam (CoICT), I have built a strong foundation in full-stack development, network architecture, and startup leadership.

Currently, as a Wireless Engineer at Huawei Technologies, I specialize in automating mission-critical workflows, significantly reducing site design times and enhancing network reliability across national infrastructure projects. My expertise spans JavaScript (ES6+), Python, React.js, Node.js, Radio Access Network (RAN) systems, and MML scripting.

How I Work as a Fractional CTO

I start every engagement with a thorough Technology Audit — a deep dive under the hood of your business. I get full access to your codebase, infrastructure, team, and processes, then deliver a detailed report covering:

Documentation
Team Assessment
Security Posture
Data Model
Disaster Recovery
Scalability
Code Review
Growth Readiness

Each category receives a proprietary score and a risk-priority rating, giving you a clear roadmap of what needs attention first. The audit eliminates guesswork and you'll know exactly where your technology stands and what it takes to get it where it needs to be.

The secret with tech audits is you will always find something that needs addressed — and I'm the person who found it, documented it, and knows how to fix it.
