I'm an Electronics & Computer Technology student passionate about Embedded Systems, IoT, Smart Energy solutions — and, more recently, building and evaluating LLM tool-calling agents.

I'm currently pursuing a Bachelor of Science in Electronics & Computer Technology at Mount Kenya University, building on my Diploma in Electrical & Electronics Engineering.

I enjoy designing systems that combine electronics, embedded firmware, and modern web technologies to solve real-world engineering problems — and I'm now applying the same systems mindset to AI agents that call tools reliably.

A real-time embedded system designed to monitor electrical parameters and protect connected loads.

Key Features

• ⚡ Real-time voltage and current monitoring
• 📊 Power, energy, and power factor measurement
• 🌐 Built-in web dashboard for live monitoring
• 🔒 Automatic protection against overvoltage, undervoltage, and overcurrent
• 📡 IoT-ready architecture for future cloud integration

A hand-built suite of multi-turn tool-use conversations for an LLM assistant, plus the schemas, validator, and a working agent that runs each scenario against a real model.

What's in it

• 📝 7 hand-written conversation logs covering chained tool use, ambiguity handling, infeasibility, tool failure, and disambiguation
• 🧩 6 strict OpenAI-compatible function schemas (calendar, email, maps, contacts) with additionalProperties: false
• ✅ Python validator that checks every conversation against the schemas using jsonschema
• 🤖 Groq-backed agent that replays each scenario turn-by-turn against openai/gpt-oss-120b and reports conformance drift
• 📐 An 8-rule quality playbook each conversation is written and reviewed against
