Exchange.ton needed a complete product built from the ground up — from initial design mockups through to public deployment. The platform aggregates real-time exchange rates from dozens of currency exchangers, requiring WebSocket connections for live price updates and a backend capable of processing thousands of rate comparisons per second. We designed the UI, built the React/Next.js frontend with server-side rendering for SEO, developed the NestJS backend with PostgreSQL and real-time Socket.io connections, containerized everything with Docker, and deployed on AWS with automated CI/CD. The entire project was delivered in 4 months.
“From design to deployment, Kozak handled everything. The real-time exchange rate aggregation works flawlessly under heavy load.”
