Timeline: 6 weeks
Team: 1 Full-stack developer
Industry: Finance / FinTech
Deployed on Vercel's global Edge Network with 100+ PoPs. Serverless functions handle API requests with automatic scaling. Zero cold starts with edge caching.
Serverless Redis for lightning-fast rate lookups. Edge-compatible caching layer reduces API latency to <50ms. Automatic cache invalidation on data updates.
Enterprise WAF with custom rulesets. DDoS protection up to 100Tbps. Bot management blocks scrapers while allowing legitimate traffic. Rate limiting per IP.
Infrastructure as Code with Terraform. DNS, CDN rules, and edge workers version-controlled. One-click disaster recovery and multi-region failover.
Automated pipelines: lint → test → build → deploy. Preview deployments for PRs. Lighthouse CI gates enforce performance budgets. Dependabot security scanning.
Vercel Analytics for Core Web Vitals. Custom Python scripts for rate trend analysis. Automated alerts via Discord webhooks for anomaly detection.
Let's discuss how we can build a high-performance web application for your business.
