About the Role
Brixio is urgently seeking a high-performance backend contractor to join the final delivery phase of a large-scale digital transformation project for a major client in the UAE.
This is

not

a management or coordination role.
This is a hands-on, high-pressure contract for someone who can

take ownership of unfinished backend modules, production issues, and integration blockers

, and close them with precision, speed, and zero hand-holding.
The platform is already live across multiple channels (web, mobile, kiosk), built with a .NET Core microservice architecture, Kafka pipelines, and third-party integrations.
Requirements
Your Mission
Own

one task at a time - no overengineering, no overthinking.
Finish

what others started: microservices, scheduling modules, test booking, internal workflows.
Stabilize

QA-critical modules and backend integrations already in production.
Decouple

systems from existing client ERP and assist in finalizing service layers.
Work directly with tech leads, QA, and DevOps to close deliverables with minimal noise.
Technical Must-Haves
• NET Core (v6+) expert
• must be able to drop in and deliver from Day 1.
Deep understanding of

microservices

,

asynchronous architecture

, and

Kafka
• Proven track record of working in

live production environments

with legacy integration, API orchestration, and refactoring.
Experience in

modular systems
• ability to work in isolated domains without reviewing the full project.
Strong understanding of

data flow

,

change tracking (CDC)

, and performance-critical service design.
Familiar with

Git standards

,

CI/CD

, containerization (Docker), and observability tools.
Database: Strong SQL (Oracle preferred), must handle complex joins, data consistency, and schema evolution.
Mindset & Execution
You work

clean, fast, and alone

if needed.
You don't need to "understand the whole system" - you slice it, take your piece, and

ship it
• You will be judged by

speed and quality of execution

, not process.
You ask questions only when needed, and you don't wait for perfection.
Ready to join, hit the ground running, and clean up a complex, mission-critical backend?
Send your GitHub, LinkedIn, and 3 shipped projects

(no fluff). Interviews will be technical, direct, and fast.
