Data Layer Management: Design, optimize, and manage both relational (e.g., SQL Server, PostgreSQL) and non-relational databases, leveraging ORMs like Entity Framework while maintaining the ability to write raw, high-performance queries. Quality & Automation: Write comprehensive unit, integration, and end-to-end tests. Champion automated testing strategies to ensure application stability and continuous delivery. Technical Leadership & Collaboration: Actively participate in design reviews and code reviews. Mentoring and fostering a culture of technical excellence and shared learning.

Key Skills & Qualifications Technical Core Backend Expertise: Strong proficiency in modern .NET (.NET Core / .NET 6+) and C#, with deep experience building Web APIs, RESTful services, and microservices. Frontend Expertise: Solid experience with modern React (including hooks, state management, and modern build tools) alongside a strong foundation in TypeScript/JavaScript, HTML5, and CSS3. Integration & Systems Design: Proven experience designing and integrating complex APIs, webhooks, event-driven architectures, and third-party services. Cloud & DevOps: A cloud-agnostic mindset with experience deploying to platforms like AWS or Azure. Familiarity with Docker, containerization, and building automated CI/CD pipelines. Database Proficiency: Strong skills in database design, query optimization, and data modelling (SQL and NoSQL options). Soft Skills Generalist Aptitude: A strong ability to quickly pick up new technologies, frameworks, or languages as required by the business problem. Problem Solving: Exceptional analytical and debugging skills across distributed systems. Collaboration: Excellent communication skills with the ability to articulate technical concepts to both technical and non-technical stakeholders.
