Backend Engineering
Node.js Development
Reliable backend systems and APIs built to handle real production load.
Devomatic builds backend systems, REST and GraphQL APIs, and server infrastructure using Node.js, designed for reliability, security, and scale under real production traffic.
99.9%
uptime target on production backend infrastructure
Typical timeline
4-12 weeks depending on integration and scale requirements.
Overview
The backend is where reliability actually gets tested, under real traffic, real edge cases, and real failure modes. We build Node.js backends with clear service boundaries, proper error handling, and monitoring from day one, not added after the first outage.
This includes REST and GraphQL APIs, authentication and authorization layers, background job processing, and integrations with third-party services and payment providers.
We design for the load you'll actually have, not a hypothetical scale that adds complexity for no benefit. Where it matters, we build in caching, queuing, and horizontal scaling from the start.
Who needs this
- Businesses needing a custom API layer for web or mobile apps
- Companies with backend systems struggling under real production load
- Teams needing secure integrations with payment or third-party providers
- Organizations replacing brittle legacy backend infrastructure

Process
How we deliver this
Discover
1-2 weeksWe audit your current systems, interview stakeholders, and map the workflows that matter most before a single line of code is written.
Architect
1-2 weeksWe design the data model, integrations, and UX flows, then lock a technical spec so scope stays honest.
Build
4-10 weeksEngineers ship in weekly increments with a staging environment you can click through from week one.
Automate & test
1-2 weeksWe wire up AI and automation layers, run QA, load testing, and security review before anything touches production.
Scale
ongoingWe launch, monitor, and hand over a 30/60/90-day optimization plan backed by real usage data.
