Full-stack developer | Websites, apps & bug fixes

Cover image for This work represents my broader

This work represents my broader full-stack development services across websites, web applications, native iOS apps and backend systems. I build complete digital products from concept to deployment, including responsive interfaces, APIs, databases, authentication, real-time features, dashboards, integrations and production infrastructure. My work covers both frontend and backend development, with a strong focus on performance, maintainability, scalability and user experience. I also handle debugging, optimization, deployment and ongoing technical improvements after launch. Depending on the project, I work with technologies such as Swift, SwiftUI, React, Next.js, Node.js, TypeScript, PostgreSQL, Redis, Docker and Linux. The goal is always the same: deliver a reliable, modern product that works smoothly across devices and is ready for real-world use.

Cover image for I designed and developed iwesley.dev

I designed and developed iwesley.dev (http://iwesley.dev) as my personal developer portfolio, built to show both my technical work and who I am beyond the code. Instead of creating a traditional portfolio with a simple list of projects, I wanted the website to feel like an interactive experience. Visitors can explore my work, learn more about me and discover the different projects, products and technologies I work with. The website features a custom responsive design, interactive elements, project showcases and a distinctive dark visual identity with purple accents. It was designed from the ground up to work across desktop and mobile while remaining fast and easy to navigate. The project combines frontend development, responsive design, UI/UX, performance optimization and my own personal branding into one complete web experience.

Cover image for Nivora is a music and

Nivora is a music and social listening platform that I designed and developed from the ground up. I built the native iOS experience, web platform and backend infrastructure, combining music discovery and playback with real-time social features. Users can discover music, build playlists, connect with friends and creators, chat, share music and listen together through Nivora Pulse. The platform also includes synced lyrics, creator tools, live radio, notifications, profiles, music libraries and personalized discovery experiences. Behind the product, I built APIs, real-time communication, authentication, database infrastructure, caching and deployment workflows to support both the iOS and web applications. Nivora is an ongoing product and one of my largest full-stack projects, covering product design, native iOS development, frontend development, backend engineering and infrastructure.

The Blockchain Virus: How It Detects and Heals Itself 🦠 Imagine if every piece of data could protect itself — like a digital virus that spreads, checks its copies, and deletes any infection automatically. That’s exactly how blockchain works. In this video, you’ll see how each block copies itself across thousands of computers, how the network detects an attack, and how consensus heals the chain without a single human involved.
