About This Role

Senior Full-Stack .NET Developer (Microservices | CRM | AI | Architecture)

Dubai (On-site / Hybrid)
Persian Horizon
Building an Advanced CRM & Sales Intelligence Platform

We are NOT hiring a typical developer.

We are looking for a high-level engineer who can design, analyze, and build systems — not someone who only codes features.

Core Requirements (Non-Negotiable)

• Expert in .NET (ASP.NET Core, Web API, MVC)
• Strong experience with Microservices Architecture
• Deep understanding of Clean Architecture / SOLID principles
• Advanced SQL Server (Database Design, Performance Optimization) and MongoDB
• Real Full-Stack capability (Backend-focused, but able to handle frontend integration)

Backend & Architecture (Must Be Strong)

• Design and build scalable API-based systems
• Experience with:
• Redis / Caching
• Message Brokers (RabbitMQ, Kafka, etc.)
• Background Services / Workers
• Strong in:
• Async programming & performance optimization
• System design & architecture decisions

External Integrations (Real Experience Required)

You must have built real systems using:

• Third-party APIs
• Payment Gateway integrations (bank connection, callbacks, security)
• WhatsApp / Email infrastructure (automation via code)
• Authentication systems (JWT, OAuth)

AI Integration (Important)

• Hands-on experience with AI APIs (OpenAI or similar)
• Ability to integrate AI into real systems (automation, analysis, workflows)

Frontend (Practical Level)

• Strong understanding of:
• JavaScript (ES6+), HTML, CSS
• At least one framework (React / Vue / Angular)
• Ability to:
• Consume APIs and build functional UI
• Implement dashboards (KPIs, charts, tables, filters)
• Handle forms, validation, and dynamic UI

CRM & Business Understanding (Critical)

• Understanding of:
• CRM systems
• Sales pipelines, leads, marketing flows
• Ability to:
• Analyze business logic
• Collaborate on system-level decisions (not just coding)

Engineering Mindset

• Clean, scalable, maintainable code
• Strong analytical thinking
• Ownership mindset
• Experience with Git, code reviews, basic testing

Bonus (High Priority)

• Real portfolio / GitHub / live systems
• Experience building CRM or dashboards
• Experience in high-scale systems

Important

If your experience is limited to basic CRUD applications,
this role is NOT a fit.

We are building a serious system and need someone who can think and build at a high level.
