Core Responsibilities

Primary Functions

Architect, develop and maintain scalable server‑side solutions using C#, .NET Core/Framework, ASP.NET MVC/Web API to support business logic and data processing.
Build responsive, high‑performance front‑end applications using JavaScript/TypeScript and frameworks such as Angular or React, integrating seamlessly with .NET back‑end services.
Design, implement and optimise relational databases (SQL Server, PostgreSQL) and NoSQL stores where applicable; write complex queries, stored procedures, views and manage data access layers.
Create and consume RESTful APIs, Web Services and microservices architectures enabling modularity, scaling and integration with third‑party systems.
Lead the entire software development life‑cycle (SDLC) from requirements gathering, design, coding, testing, deployment, support and maintenance in an agile environment.
Write clean, maintainable, well‑documented code following SOLID principles, design patterns and software engineering best practices.
Conduct unit tests, integration tests and ensure high quality through code reviews, continuous integration/continuous delivery (CI/CD) pipelines and automated testing frameworks.
Deploy applications to production and manage releases, monitor system health, troubleshoot performance issues, debug production incidents and optimise uptime.
Collaborate across cross‑functional teams (product, UX, QA, DevOps, operations) to translate business requirements into technical solutions and deliver on time with high quality.
Mentor and coach junior developers, share best practices, participate in architectural decision‑making and facilitate knowledge transfer within the team.
Maintain front‑end component libraries, UI modules, style guides and ensure responsive design, accessibility and mobile compatibility across browsers and devices.
Integrate cloud services (Azure, AWS, GCP) and containerisation/orchestration technologies (Docker, Kubernetes) into the full‑stack deployment model to support scalability and resilience.
Manage version control (Git, TFS), branching strategies, release pipelines and environment configurations (development, staging, production).
Improve application performance by profiling code, optimising database queries, reducing latency, implementing caching (Redis/Memcached) and efficient front‑end bundling.
Ensure application security: implement authentication/authorization, protect against XSS/CSRF/SQL injection, apply secure coding guidelines and maintain compliance.
Participate in architecture and design discussions: propose and evaluate new technologies, frameworks, tools and establish standards for the full‑stack environment.
Maintain comprehensive documentation of APIs, system architecture, database schemas, deployment instructions and run‑books for operational continuity.
Balance feature development with technical‑debt management: identify refactoring opportunities, improve test coverage, optimise codebase and reduce maintenance overhead.
Stay current with emerging .NET ecosystem, front‑end frameworks, cloud platforms and industry trends; bring innovation into development workflows.
Provide on‑call support or production incident response as needed, restore service quickly, perform root‑cause analyses and propose preventive actions.
Participate in sprint planning, backlog grooming and agile ceremonies, collaborate on user stories, deliver incremental value and ensure alignment with business priorities.

Secondary Functions

Support ad‑hoc reporting or data‑extraction requests across the application stack.
Contribute to the technology roadmap and recommend full‑stack improvements, tools and processes.
Collaborate with business units to transform requirements into engineering deliverables.
Participate in agile practices including stand‑ups, sprint reviews and retrospectives.
