Alpina Tech builds edge-first applications on Cloudflare Workers for teams that need code running in 300+ locations with zero cold starts. We design architectures around Cloudflareβs full developer platform β Workers, KV, D1, R2, Queues, and Durable Objects β to deliver globally distributed services without origin servers.
Edge API & Application Development
We build production services designed for Workersβ V8 isolate runtime:
- REST and GraphQL APIs using Hono, itty-router, or raw Workers fetch handler
- Full-stack applications with Cloudflare Pages + Workers for server-side logic
- Authentication and authorization middleware at the edge (JWT validation, OAuth flows)
- A/B testing, feature flags, and geolocation-based routing executed before requests reach your origin
- Rate limiting and bot protection using Workers in front of existing APIs
Cloudflare Data Services (KV, D1, R2, Durable Objects)
Cloudflareβs data platform eliminates the need for external databases in many use cases. We architect:
- Workers KV β globally replicated key-value store for configuration, feature flags, and cached content
- D1 β SQLite at the edge for relational data that needs to live close to your Workers
- R2 β S3-compatible object storage with zero egress fees for files, media, and backups
- Durable Objects β strongly consistent, stateful compute for real-time collaboration, WebSocket coordination, and distributed counters
- Queues β message queues for async processing between Workers without external brokers
Migration to Cloudflare Workers
We migrate workloads from Lambda, traditional Node.js backends, and other edge platforms:
- Runtime compatibility audit β identifying Node.js APIs that need edge-compatible alternatives
- Express/Fastify route mapping to Hono or itty-router patterns
- AWS Lambda function conversion with API Gateway parity
- Database migration from DynamoDB to KV/D1 or from S3 to R2
- Incremental migration β Workers as reverse proxy in front of existing origin while services move edge-side
Wrangler, CI/CD & Deployment Workflows
Production Workers deployments need automation and safety:
- Wrangler configuration with environments (dev, staging, production)
- GitHub Actions pipelines for automated deploy on merge
- Preview deployments per pull request with isolated KV/D1 namespaces
- Secrets management and environment variable segregation
- Rollback procedures and deployment versioning
We integrate Workers deployments into your broader infrastructure pipeline.
How We Approach Cloudflare Workers Projects
Edge Feasibility Assessment Not every workload fits the edge model. We evaluate CPU time limits, memory constraints, and data access patterns to determine what runs on Workers versus a traditional backend β and design the boundary between them.
Data Architecture We map your data needs to Cloudflareβs storage primitives: KV for read-heavy global state, D1 for relational queries, R2 for objects, Durable Objects for stateful coordination. The right choice per data type avoids performance bottlenecks.
Iterative Build & Deploy Workers deploy in seconds. We use this speed for rapid iteration β shipping features to preview environments, testing across regions, and promoting to production multiple times per day.
Performance Validation We benchmark Workers from target geographies, measure P50/P99 latencies, and validate data consistency across KV replicas. Your team receives performance baselines and alerting dashboards.
Technology Stack with Cloudflare Workers
Edge Runtime & Frameworks
- Cloudflare Workers β V8 isolate execution across 300+ global locations
- Hono β lightweight, multi-runtime framework optimized for Workers
- Cloudflare Pages β static site hosting with Workers integration for dynamic routes
- Remix on Cloudflare β full-stack React framework with Workers as server runtime
Data & Storage
- Workers KV β eventually consistent global key-value store
- D1 β edge SQLite database with read replication
- R2 β zero-egress object storage, S3-compatible API
- Durable Objects β strongly consistent stateful edge compute
- Queues β native message queue between Workers
Ecosystem Integration
- Cloudflare DNS, CDN, WAF β unified network layer for security and performance
- Neon, Supabase, PlanetScale β external PostgreSQL/MySQL when D1 doesnβt fit
- Stripe, Auth0, Clerk β SaaS integrations running at the edge
- OpenTelemetry, Sentry β observability for distributed Workers execution
Business Benefits
- 300+ locations, zero config β every Worker deploys globally by default. Your API responds from the nearest Cloudflare datacenter without region selection or multi-region orchestration.
- Zero cold starts β V8 isolates boot in under 5ms. Unlike Lambdaβs 100msβ5s cold starts, Workers respond instantly on every request, including the first one after idle.
- No egress fees on R2 β storing and serving files from R2 eliminates the bandwidth costs that make S3 expensive at scale. Media-heavy applications save significantly.
- Unified security stack β Workers run behind Cloudflareβs WAF, DDoS protection, and bot management automatically. No separate CDN, firewall, or load balancer to configure and pay for.
- Sub-cent per million requests β Workers pricing starts at $0.50 per million requests. For API workloads, this is orders of magnitude cheaper than always-on containers or VM-based hosting.
- Reduced architectural complexity β KV, D1, R2, Queues, and Durable Objects replace what would be 5+ separate AWS services (DynamoDB, RDS, S3, SQS, ElastiCache), managed from a single platform with a single CLI.
