Client Project

Shitonova

Full-stack food delivery platform built for a food service business. Features user authentication, a full menu system, custom order requests, and real-time order tracking from kitchen to door.

The client needed a way to take orders online and give customers visibility into their delivery status. I built the entire platform from scratch using Next.js and TypeScript — auth with protected routes, a menu with categories and filtering, a custom order flow for special requests, and a live status tracker. Deployed on Vercel with CI/CD on every push.

Sheppy's Publications

Professional multi-page website for a Ghanaian publishing house. Covers service listings, author submission flow, blog, and contact.

Built for a publishing house in Ghana that needed a credible online presence to attract authors. I translated their business requirements into a clean Next.js site with a service showcase, a step-by-step publish-with-us flow, blog, and newsletter subscription. Source code is private per client agreement.

WhitetoGray

Elegant event planning platform with booking flow, service showcase, portfolio gallery, and client testimonials.

An event planning company in Ghana needed a site that felt as premium as their service. I focused heavily on design — large imagery, smooth scroll, a services breakdown, a portfolio gallery of past events, and a booking form. Built with Next.js and TypeScript, deployed on Vercel.

RAG Technical Assistant

Production RAG pipeline over 389 arXiv papers — 1,500 semantic chunks in ChromaDB, 0% zero-result rate, deployed with MLflow tracking and CI/CD to Hugging Face Spaces.

Built a full retrieval-augmented generation system to answer technical questions over a corpus of ML research papers. Ingested and chunked 389 arXiv PDFs into ChromaDB with sentence-transformer embeddings. Built a FastAPI backend with dual-mode LLM (Mistral-7B local / API fallback), MLflow tracking across 3 evaluation runs, and automated CI/CD deployment to Hugging Face Spaces.

CyberGuard Multi-Agent Assistant

5-agent LangGraph StateGraph with typed state, conditional routing, and a Critic retry loop. 85% quality score at 7.6s end-to-end.

Designed a multi-agent system for cybersecurity research using LangGraph. The Supervisor routes queries to specialised agents — RAG (ChromaDB over security papers), WebSearch (Tavily), CodeAnalyst, and a Critic that retries low-quality responses. Built with Groq LLaMA 3.1 for speed, FastAPI serving, MLflow per-query tracking, and GitHub Actions CI/CD to Hugging Face Spaces.
