I’m a Software Engineer and Solution Architect with over 15 years of experience designing and building scalable, maintainable, and high-performing systems. I’ve worked with companies across Europe and the U.S., creating software that handles complex workflows and high traffic. From 2008 to 2015, I worked remotely for a Swiss-based company in Geneva. From 2015 to 2020, I joined an Italian company in Turin, which was later acquired by a U.S. firm, where I continue full-time. Over the years, I’ve led architecture, backend, and frontend design for ERP systems, SaaS platforms, and enterprise-grade applications for clients such as Swissport, the Red Cross, and the World Organization of Scout Movement. I specialize in software architecture, microservices, micro frontends, and performance optimization. I also lead teams when needed, guiding developers, reviewing code, and ensuring projects stay on track. I have hands-on experience with Symfony, Python, NodeJS, Angular, Vue.js, React, Flutter, and React Native, and I work extensively with Docker, Kubernetes, and CI/CD pipelines to enable reliable, cloud-native deployments. I enjoy turning complex requirements into clear, efficient architectures and helping teams implement them successfully. On Upwork, I’m available for part-time work (around 30 hours per week) to design, build, or improve web and mobile systems. If you need someone who can architect, implement, and lead complex solutions, I can help you deliver systems that are reliable, maintainable, and ready to scale.

I’m Farid Ghaderi, a fullstack developer with strong experience in building scalable, reliable, and maintainable systems. I specialize in Node.js, Express.js, Nestjs, Reactjs and Socket.io, and I’m highly skilled in working with both SQL (PostgreSQL) and NoSQL (MongoDB, Redis) databases. My focus is on writing clean, efficient code and developing backend solutions that are both practical and robust. Beyond technical skills, I value problem-solving, teamwork, and clear communication, qualities that ensure smooth collaboration and successful project delivery. I’m also comfortable working with modern development tools and environments, including Linux, Docker, and Kubernetes, and I have solid experience with JavaScript, TypeScript, and React.js for full-stack projects. If you’re looking for a fullstack engineer who can combine technical expertise with reliability and attention to detail, I’d be glad to help bring your project to life.
