Back to original languageAbout Ivan
I am a Full Stack developer specializing in JavaScript and modern web development ecosystems, with experience creating robust, dynamic, and business-oriented applications. I work on both frontend and backend, building complete solutions that combine good design, performance, and scalability.
On the frontend, I use JavaScript, TypeScript, React, and Next.js, with a clear focus on usability, SEO, accessibility, and reusable components. I develop clean, intuitive, and optimized interfaces, from landing pages to administration panels or complex applications with global state and real-time communication.
On the backend, I work with Node.js, REST APIs, JWT authentication, session control, relational and non-relational databases (MySQL, PostgreSQL, Firebase, Firestore, MongoDB). I also design well-organized architectures, coherent data models, and secure, scalable, and easy-to-maintain endpoints.
I have developed applications such as:
• Dashboards and control panels for financial management, metrics, and reporting.
• Money Manager-style applications, with categories, budgets, advanced filters, and cloud synchronization.
• Systems with Next.js and Firebase, with login, protected routes, and real-time data.
• Fully customized professional websites for personal branding or companies.
I bring a constant focus on code quality, communication, and value delivery. I can help you define the architecture, create the technical design, implement all functionalities, integrate external services, optimize performance, and leave the project ready to scale.
If you are looking for a developer capable of turning your needs into a modern, solid, and production-ready web application, I will be delighted to collaborate with you.
