AI engineer building systems for education & security
Cover image for Excited to share my first
Excited to share my first step into building and shipping in public. Over the past months, I’ve been focused on building systems that sit at the intersection of AI, education, and real-world safety. Two projects I’ve been working on: • BedfordLearn — an AI-powered learning platform that simplifies education for primary and secondary students • White Waters Sentinel — a real-time incident reporting and intelligence platform designed for faster response and better situational awareness Both projects are built around a simple idea: technology should make complex systems easier to understand and act on. I’m currently open to collaborating on AI systems, full-stack platforms, and automation tools that solve meaningful problems. More to come soon.

Cover image for Satellite Intelligence Integration in Progress
Satellite Intelligence Integration in Progress 📡 We are currently upgrading the White Waters Sentinel (W2S2) platform to support satellite-enabled monitoring, geospatial intelligence, and early warning capabilities for nationwide security. Right now, our team is working closely with our satellite imagery provider to seamlessly integrate their satellite capabilities into the system, working through the technical API documentation to map out real-time geospatial data ingestion. Looking forward to bringing enhanced operational intelligence and mission-critical response tools to all 36 states and the FCT. Stay tuned for the upgrade!

Cover image for I just published a practical
I just published a practical guide: “How to Choose the Right AI Framework for Your Use Case.” If you're evaluating AI agents (LangChain, CrewAI, no-code tools, etc.), the real question isn’t what’s popular; it’s what fits your business. In this guide, I break down: 1. Team technical capability 2. True cost of ownership 3. Matching tools to real use cases 4. How company size impacts your decision Includes decision flowcharts, cost insights, and a roadmap from prototype to production. Key insight: The winners in AI aren’t chasing hype. They test fast, learn quickly, and scale what works. Read here: Medium: https://shorturl.at/YNyU1 Ready Tensor: https://shorturl.at/X8VgR What’s been your biggest challenge in choosing AI tools?

Lately, I’ve been deep in the world of Laravel and Vue.js. Crafting web apps that are fast, scalable, and built to last. There’s something really satisfying about turning a rough idea into a clean, functional product that just works. I love collaborating with startups and small teams to bring their vision to life. If you’re building something exciting and need a reliable full-stack dev, I’d love to connect!
