I build full-stack AI and real-time systems with RAG, React, and Node.
ZimbabweWhat I'm looking for
I’m currently pursuing a B.Tech. in Artificial Intelligence and Data Science at Galgotias College of Engineering and Technology (expected). I focus on turning research-style ideas into working products, especially where Retrieval-Augmented Generation (RAG) and real-time experiences intersect.
In my AI work, I engineered a full-stack multi-agent RAG system powered by Groq LLaMA 3.3 70B to automate literature reviews, research gap analysis, and citation Q&A. I designed a custom RAG pipeline using ChromaDB with user-scoped cosine similarity retrieval to enforce isolated data boundaries.
I also optimize for practical deployment constraints. For example, I reduced memory footprint by ~90% by replacing 2GB+ neural embedding models with lightweight TF-IDF vectors—while keeping the system’s retrieval behavior usable.
On the software side, I’ve built full-stack, authentication-secured, real-time experiences—like a React.js + Node.js collaborative code editor with live cursors using Socket.io, and a blockchain-powered carbon credit ledger using SHA-256 hashing with JWT/bcrypt-backed stateless sessions. I enjoy building clean APIs, reliable persistence, and systems that fail gracefully.
Experience
Work history, roles, and key accomplishments
GreenChain
Built a full-stack telemetry dashboard to stream and visualize simulated IoT environmental energy data. Implemented a server-side SHA-256 cryptographic blockchain ledger for immutable telemetry in MongoDB Atlas and added bcrypt password hashing with JWT authentication.
AI Research Assistant
Engineered a full-stack multi-agent RAG system to automate literature reviews, research gap analysis, and citation Q&A. Built a custom ChromaDB retrieval pipeline with isolated data boundaries and optimized deployment by replacing large embedding models with lightweight TF-IDF vectors to reduce memory usage by ~90%.
PairCode Collaborative Editor
Developed a full-stack real-time collaborative code editor with live cursors, selection highlighting, and code sync across 22+ languages. Implemented PostgreSQL persistence with auto-save, snapshot versioning, and one-click restore, and used a Dockerized Piston execution engine for sandboxed multi-language runs with stdin/stdout/stderr.
