I build high-performing full-stack web platforms for healthcare, education, and payments.
SerbiaWhat I'm looking for
I've built production web platforms across healthcare, education, payments, and e-commerce. At SuperAdmins, I architected a telemedicine platform with React.js and Node.js, including WebRTC video consultations, a GraphQL API gateway, and HIPAA-compliant PostgreSQL data handling.
I improved application performance by 40% while maintaining 99.9% availability. Previously at CODETIQ, I built payment processing and banking integration APIs, reduced fraudulent transactions by 75%, and cut transaction routing time from three seconds to 500ms with a microservices architecture.
My work spans TypeScript, React.js, Vue.js, Angular, Node.js, cloud services, APIs, and real-time systems. I work independently or collaboratively, communicate clearly, and stay current with evolving web technologies.
