Jonathan B.

Hi, I'm Jonathan. For over 6 years, I've been architecting and building high-performance, scalable, and user-centric digital products for startups and established enterprises. I'm not just a developer who writes code; I'm a dedicated technology partner who bridges the gap between your vision and a market-ready application that drives results. My expertise lies at the intersection of sophisticated back-end engineering and polished, intuitive user experiences, with a specialized focus on mobile application development. Whether you need a robust web platform or a stunning iOS and Android app, I have the full-stack skill set to bring your project to life from concept to launch and beyond. What I bring to your project: * Full-Cycle Development: I handle everything—from initial architecture design, database modeling, and API development to pixel-perfect front-end implementation and cloud deployment. * Mobile-First Mindset: Specializing in mobile, I build beautiful, high-performance apps using both cross-platform frameworks like React Native for efficiency and native Swift/Kotlin for maximum performance and platform integration. * Scalability & Performance: I write clean, efficient code and design systems with future growth in mind, ensuring your application can handle user demand and is built on a solid foundation. * Clear Communication & Partnership: I believe in transparent, proactive communication and see myself as an extension of your team. I'm committed to understanding your business goals and delivering solutions that provide real value. My Core Services: * Web Development: Full-stack development of complex web applications, dashboards, and SaaS platforms. * Mobile App Development: * Cross-Platform (React Native) * Native iOS (Swift, SwiftUI) * Native Android (Kotlin, Jetpack Compose) * API & Backend Development: Secure, scalable RESTful and GraphQL APIs using Node.js, Python, and Go. * Cloud & DevOps: Cloud architecture (AWS, GCP, Firebase), CI/CD pipeline automation, and containerization (Docker). * Technical Consulting: Architecture review, technology stack selection, and product roadmap strategy. Let's build something amazing together. If you're looking for a reliable and experienced engineer to lead your next project, send me a message. I'd love to hear about your goals.
