Full-Stack Developer and AI Integration Engineer
Freetown, Sierra Leone
I build web applications and AI-powered tools using React, Node.js, and the Anthropic SDK. Self-taught, based in Sierra Leone, and shipping to production since early 2025. My recent work includes a real-time news platform, an AI-assisted reading app, and a blockchain application on Hedera Hashgraph.

Who I Am
I am a self-taught full-stack developer and current BSc Computer Science student based in Freetown, Sierra Leone. I started from scratch in early 2025 and have been shipping real applications ever since.
My day-to-day work is building web applications and integrating AI into products using React, Node.js, and the Anthropic SDK. Along the way I picked up Anthropic AI engineering certifications and a Hedera Hashgraph developer credential. I am looking for remote engineering roles where I can do real work from day one.
Core Expertise
My Path
15 months of self-directed learning and real-world shipping
Started building and shipping real applications from scratch. Learned React, Node.js, Express, and MongoDB by building actual projects rather than tutorials, deployed them to Vercel, and delivered the first client work including news platforms and portfolio sites.
Earned Anthropic developer certifications covering the Claude API, Model Context Protocol, and agent architecture. Completed the Hedera Hashgraph Developer Course and received the HCERT credential, verified on-chain. Added Python and Flutter to the stack.
Actively building AI-integrated and blockchain-enabled applications. Available for full-time roles, freelance projects, and collaborative ventures worldwide.

My Work
A selection of projects across full-stack, AI, and blockchain development
A multi-category news platform built with Node.js and Express. The breaking news ticker pushes updates to the client using Server-Sent Events rather than polling, which keeps the connection open and reduces unnecessary requests. Articles are stored in MongoDB with a category index for fast filtered queries. Authentication uses JWT with refresh token rotation so sessions persist across page reloads without storing credentials client-side. Deployed on Vercel with serverless API routes.
A reading curation platform built with React on the frontend and a Node.js/Express API on the backend. Content is organised by curator collections rather than algorithmic feeds, which was a deliberate product decision to keep the reading experience focused. The React frontend fetches collection data from the API on route change and caches responses in component state to avoid redundant network calls. Deployed on Vercel with the API running as a serverless function.
A portfolio site built for a researcher and academic. The brief required a clean reading experience for long-form writing, so the layout prioritises typography and minimal distraction. Built with vanilla HTML, CSS, and JavaScript to keep load times fast and avoid framework overhead for a static content site. A lightweight Node.js contact handler on Vercel processes enquiries without a third-party form service. Custom domain configured and live.
A decentralised application built on the Hedera Hashgraph network using the Hedera JavaScript SDK. Uses the Hedera Consensus Service to write tamper-evident records to a public topic, which means any third party can verify the log without trusting a central server. Hedera was chosen over Ethereum because transaction fees average under $0.001, which made it practical for frequent writes. The HCERT credential for this work is verified on-chain and viewable on Hashscan.
