FAQ
Aetherius provides senior Node.js engineers for team augmentation and full-cycle backend development engagements. We build APIs, real-time services, backend infrastructure, and server-side logic that supports mobile and web applications. We work primarily with software companies that need backend capacity alongside their existing mobile projects, without bringing in a separate vendor to manage.
In most cases, we present pre-vetted senior candidates within 5–10 business days. If a profile isn't available for your timeline, we tell you upfront. Get in touch and we'll match based on your exact stack and project requirements.
Yes. Many of our clients run mobile and backend projects in parallel and need developers who understand how the two interact, around APIs, authentication, real-time data sync, and shared business logic. We can place Node.js developers who cover the backend layer without you needing to coordinate between separate vendors or deal with communication gaps between teams.
Scalability is an architecture decision, not something you add later. Our senior Node.js engineers assess your requirements upfront, expected load, real-time constraints, third-party integrations, and data structure, and design the backend accordingly. If there are existing scalability risks in your codebase, we flag them before they become production problems.
Every developer goes through technical screening that covers Node.js architecture, API design, asynchronous patterns, performance optimization, and the ability to work independently in complex, enterprise-grade codebases. We don't label mid-level developers as seniors. If a profile doesn't precisely match your requirements, we say so before you meet them.
Yes. Aetherius developers are experienced in white-label delivery, they align with your workflows, communication standards, and team culture. They operate as your team members, not as an external vendor. This includes participating in client-facing technical reviews or architecture discussions when needed.
It depends on how much control and involvement you want:
- Team Augmentation — senior Node.js developers embedded directly in your team, fitting your existing workflows. Best for long-term backend capacity needs.
- Outsourced Team — a full backend team managed by us, focused on delivery. Best when you want results without management overhead.
- Part-Time Support — flexible part-time Node.js experts who contribute immediately. Best for ongoing needs that don't require full-time commitment.
- Sprint-Based — backend work scoped and delivered sprint by sprint. Best when scope fluctuates alongside frontend or mobile development.
Pricing depends on seniority level, project scope, and engagement model. We don't publish flat rates because every project is different, but pricing is always transparent with no hidden fees. Use the Aetherius Cost Calculator for a custom estimate, or get in touch and we'll break it down based on your actual requirements.
