I am a Full Stack Developer with over five years of experience building scalable, responsive web applications. My expertise spans a wide range of modern technologies, including React.js, Vue.js, Node.js, PHP, Laravel, Golang, Rust, and MongoDB. I take pride in writing clean, maintainable code and thrive in collaborative environments where communication and cross-functional teamwork are essential.
Throughout my career, I’ve delivered successful solutions across various industries. I’ve worked on high-impact platforms, such as a financial crime prevention system at FraudAverse GmbH, where I developed backend features using Rust and optimized MongoDB performance to handle large-scale data processing. At Red Acre LTD, I helped build an innovative trading platform using React and Node.js, integrating financial services and ensuring robust performance for large user bases.
As a freelancer, I’ve developed a strong client base—primarily through Upwork and referrals from fellow developers—thanks to a consistent track record of delivering high-quality results. I specialize in full stack projects with a focus on Vue.js, Golang, and React.js, and I’m especially comfortable managing end-to-end project execution. I’m also the founder of Dario Tech, and I’m open to freelance and B2B collaboration opportunities.
My frontend experience includes working with modern frameworks and experimenting with microservices architectures. For instance, at GlobalSoft, I contributed to cutting-edge micro frontend development, and at Act2Access, I helped build a powerful ad blocker detection tool using Vanilla JavaScript and Vue.js—later successfully deployed by a major German tech publication. I’ve also had the opportunity to develop complete platforms from the ground up, such as an educational platform built with Laravel and Nuxt.js, and user-facing solutions for telecom and hotspot services.
On the backend, I’ve become proficient in creating APIs, integrating with third-party services, and managing microservices and containerized environments using Docker. My early experience at SPARK Business Park introduced me to Golang and Docker, where I contributed to backend microservices with PostgreSQL and gained a strong understanding of scalable system design.
