Xela Oladipupo
React Native & Full-Stack Developer

My journey began with a strong foundation in programming languages like JavaScript, which provided me with the technical tools to bring imaginative ideas to life. My love for aesthetics and user experience design quickly led me down a path of developing visually stunning, highly functional applications and websites that people genuinely enjoy using.

As a Full-Stack Developer, I specialise in React, React Native, Next.js, Node.js, and MongoDB. I enjoy owning the entire product lifecycle — from wireframing and UI design through to deployment and performance optimisation — delivering solutions that are fast, accessible, and built to scale across every screen size and platform.

My work spans the complete technology spectrum. On mobile, I build cross-platform iOS and Android applications with React Native and Expo — shipping real products used by thousands of people daily, from AI-driven fintech platforms to on-demand restaurant ordering apps. On the web, I create high-performance applications with Next.js, React, and TypeScript, always optimising for Core Web Vitals, search engine visibility, and long-term code maintainability. I treat every project as a product, not just a codebase.

On the server side, I architect and build RESTful and GraphQL APIs with Node.js, Express, and NestJS, backed by MongoDB and PostgreSQL databases and deployed on cloud platforms including Vercel, Railway, and AWS. I am also experienced in blockchain development — authoring smart contracts in Solidity and Rust on Ethereum and Solana — and in integrating large language model capabilities using OpenAI, Claude, and Gemini APIs into production applications.

Over the course of my career I have shipped more than ten production-ready applications and helped grow user bases to over twelve thousand active users. My open-source repositories have collectively earned more than two hundred GitHub stars, which reflects the quality and real-world utility developers find in my work. Whether the brief calls for a consumer mobile app, an enterprise SaaS dashboard, or a blockchain-powered platform, I bring the same level of craft, ownership, and accountability to every engagement.

I am currently open to freelance projects, remote contract work, and full-time opportunities. Whether you need a quick MVP to validate a business idea, a security or performance audit on an existing product, a complete mobile and web platform built from scratch, or ongoing development support for a growing team — I bring transparency, technical rigour, and clear communication to every project. Let's build something great together.
