Services

What we build

Full-cycle development — we take a product from first conversation to production and keep it running.

Custom Software Development

Bespoke systems built around your actual processes — internal platforms, automation, data-heavy back offices.

Web Development

Corporate sites, client portals, e-commerce and SaaS platforms with fast, accessible modern frontends.

Mobile Applications

iOS and Android apps — native or cross-platform — built for real-world performance and offline reliability.

Cloud & DevOps

Infrastructure as code, CI/CD pipelines, containerisation, observability and cost-aware cloud architecture.

Integrations & APIs

Connecting ERP, CRM, payment providers and third-party services into one coherent, documented system.

Support & Maintenance

Continued development, SLA-based support, security updates and technical audits of existing codebases.

About the company

An engineering partner, not a vendor

Node9 LLC is a software development company registered in Azerbaijan. We work as a small, senior team that takes responsibility for the architecture, delivery and long-term maintenance of every system we build.

Our clients range from local businesses digitalising their operations to international teams looking for a dependable development partner in the South Caucasus. Whatever the size of the project, you talk directly to the engineers writing the code.

  • Fixed scope and transparent estimates before work starts
  • Working builds every two weeks, no black boxes
  • Full source code and documentation handed over to you
  • Long-term support after launch, not a handover and goodbye

Process

How a project runs

A predictable sequence with a clear deliverable at every stage.

  1. Discovery

    We study your processes, goals and constraints, then define the scope, timeline and success criteria in writing.

  2. Design & architecture

    Technical architecture, data model and interface design — all agreed with you before a line of production code is written.

  3. Development

    Two-week iterations, each ending with a build you can actually use. Transparent progress and direct access to the team.

  4. Launch & support

    Deployment, monitoring, documentation and handover — followed by continued development and support after release.

Reference architecture sketch A hand-drawn diagram: a client calls an API over HTTPS; the API reads and writes a Postgres database and puts jobs on a queue; a pool of N workers polls that queue and writes results back to the database. Delivery is at-least-once, so the workers are idempotent. Client web · mobile API stateless Postgres Queue Worker ×N HTTPS SQL enqueue poll write at-least-once — workers are idempotent
What step two produces Day one, on the board: the shape of the system, agreed before any code is written.
