/ Crypto Monitoring Platform | 2026
A full-stack crypto monitoring prototype combining live market polling, watchlists, alerts, persistence, and background processing.
/ Project overview
Crypto Sentry monitors cryptocurrency market data and gives users a dashboard for tracking selected assets and reviewing alert states. The product separates the user-facing Next.js application from a Node.js worker responsible for continuously polling external market data.
/ Process
The key challenge was coordinating a continuously running backend process with a user-facing application, persistence layer, alert logic, and external APIs.
A dedicated Express worker polls CoinGecko on an interval, evaluates price movement, and writes alert data into PostgreSQL through Prisma. The Next.js frontend handles authentication, watchlists, market display, and alert history, while email notification logic supports event-driven user updates.
/ The result
The project demonstrates backend-oriented full-stack development with background workers, third-party APIs, persistence, and monitoring logic rather than a purely request-response web application.
