EDGE COMPUTINGCompute where the request starts.
Edge computing is useful when it removes a round trip, protects origin, or makes personalization cheaper. We use it for auth checks, routing, caching, experiments, and failover, and we keep origin logic where edge would only add risk.
- 01Two-week auditFixed price. Domain map, risks, and a delivery plan.
- 02Working sliceOne real workflow shipped end to end.
- 03Progressive rolloutTraffic moves in steps; rollback stays ready.
- 04HandoffRunbooks, dashboards, and docs your team keeps.
P95 auth check at the edge
SaaS product launchWhat we build
Edge functions
Cloudflare Workers, Vercel Edge, Fastly Compute, and Lambda@Edge-style architectures.
Auth and personalization
Fast policy checks, segmentation, geolocation, and user context without origin round trips.
Smart caching
Surrogate keys, tag invalidation, stale-while-revalidate, and cache safety rules.
Failover and experiments
Origin fallback, regional routing, edge A/B tests, and observability per region.
Stack in production

What you get
- 01Decision matrix: what stays on origin, what moves to the edge, why.
- 02Reference function with logs, traces, and per-region cost.
- 03Cache strategy document with invalidation and rollback paths included.
- 04Failover plan to origin if a region goes dark.
Start with a two-week audit.
Fixed price. We map the domain, ship a working slice, and hand over documentation your team keeps, whatever you decide next.
