I'm a results-driven Blockchain Developer and AI Engineer with hands-on experience designing and deploying secure, scalable decentralized systems. My expertise spans smart contract development, real-time AI integration, and data science, backed by a strong academic foundation from Bournemouth University (MSc in Data Science & Artificial Intelligence, 2024–2025).
I recently completed a cutting-edge project where I built a Solana-based decentralized vehicle trust management system, integrating smart contracts (Rust/Anchor) with a Flask backend, React frontend, and real-time simulation using SUMO. The system featured advanced components such as Zero-Knowledge Proofs (ZKPs), Cross-Program Invocations (CPI), on-chain behavior validation, and blockchain access control.
On the AI side, I developed a trust scoring model using Python, Pandas, and Scikit-learn, leveraging behavior recognition, anomaly detection, and predictive analytics to classify vehicles as trusted or malicious. I also worked with federated learning, reinforcement learning, and real-time data pipelines to ensure the system was privacy-preserving and adaptable to live environments.

I’m a full-stack developer who builds fast, reliable, and intuitive web applications — helping businesses turn complex ideas into smooth, user-friendly experiences.
On the frontend, I work mainly with React, TypeScript, and modern styling tools such as Tailwind, Sass, and styled-components to deliver clean, responsive interfaces.
On the backend, I use Node.js / Express and Ruby on Rails, depending on the project’s needs, to create solid, scalable APIs. I also integrate Strapi CMS for content management when clients need a flexible, no-nonsense publishing setup.
I’m comfortable working across the entire build process — from design concepts in Figma through to production deployment — following best practices with Git, TDD, and clean code standards.
What you’ll get working with me:
Clear communication: I keep you in the loop throughout the project — no disappearing acts.
Technical depth: I bring experience across multiple frameworks and CMSs, so you get solutions that are practical and future-proof.
Reliability: I stick to deadlines, document my work properly, and deliver code you can build on.
Empathy and focus: I take time to understand your goals before I start writing a line of code.
If you’re looking for a developer who can take ownership of your project and deliver results without hand-holding, let’s have a chat.
