I design and build scalable software systems that power real-time communication, emergency response, and business operations. With strong experience across full-stack development and telecom infrastructure, I specialize in building high-performance applications using React, Node.js (Express), and modern backend architectures, alongside VoIP systems powered by Asterisk and WebRTC. I have worked on mission-critical platforms including Emergency Call Center (ECC 112) systems, real-time dispatch solutions, and enterprise applications that require reliability, speed, and seamless integration with external services. My skill set spans: • Full-stack web & mobile development (React, Next.js, React Native) • Backend engineering (Node.js, Express, Prisma, Django REST) • VoIP & real-time systems (Asterisk, SIP, WebRTC) • DevOps & infrastructure (Docker, VPS, Nginx, AWS, Linux) • Desktop applications (Electron) I enjoy solving complex technical problems, building scalable systems, and delivering solutions that have real-world impact. Open to remote opportunities, consulting, and freelance projects.
