I've built a full-stack platform for creating and publishing multimedia tours using React, TypeScript, Vite, Node.js, Express, PostgreSQL, and Prisma.
I created a visual tour builder with templates, themes, responsive previews, undo/redo, and a Leaflet and OpenStreetMap route editor supporting GeoJSON, images, audio, geolocation, and points of interest.
I've also developed a chess web application and Telegram bot, plus a Vue.js single-page application, and I set up REST APIs, JWT authentication, testing, GitHub Actions, Docker, and cloud deployment.
