About this service
Summary
Tired of brittle integrations that break every other sprint? We design and ship rock-solid backend APIs that let your apps, vendors, and legacy applications share data without meltdowns. You’ll get clean code, iron-clad security, and docs a junior dev can grok, delivered fast because we’ve built this a hundred times already.
Process
Requirements Jam – 60-min call to map data flows, auth, and edge cases.
Spec & Estimate – You approve the blueprint and fixed price.
Build Sprints – Code → review → demo every Friday or at your preferred cadence. No black boxes.
Hardening – Load tests, penetration checks, and zero-downtime migration plan.
Deploy & Monitor – We ship to prod, wire up alerts, and babysit for 30 days.
Knowledge Transfer – Recorded session, annotated codebase, open PRs merged.
