Senior Full Stack Developer (GraphQL)

Key responsibilities:

• GraphQL API Design Optimization:Develop and maintain high-performance GraphQL Schemas and APIs focusing on schema design, query optimization (batching, caching), real-time data, and schema evolution.
• Supergraph/Subgraph Architecture:Decompose monolithic schemas into manageable Subgraphs using federation or stitching techniques.
• API Consolidation and Aggregation into a Graph: Aggregate existing REST APIs, services, and underlying data stores into a sub-graph.
• Graph-to-Graph Interactions:Integrate, transform, and aggregate data across multiple GraphQL APIs.
• Full Stack MERN Development:Oversee front-end (React.js) and back-end (NEST.js / Express.js) development ensuring efficient GraphQL integration.
• Azure Cloud Implementation:Deploy, scale, and maintain applications using Azure Cloud, including serverless architectures if required.
• UI/UX Accessibility:Convert design mockups (e.g., Figma) into responsive, accessible interfaces adhering to design systems.
• Quality Assurance:Write and execute unit and integration tests (e.g., Jest.js) to ensure code quality and stability.
• CI/CD DevSecOps:Build and manage automated pipelines that incorporate security and accommodate GraphQL schema changes.
• Production Support:Monitor, troubleshoot, and optimize performance in production environments.
• Architectural Contribution:Engage in design discussions to evolve scalable, secure architectures for GraphQL APIs and microservices.
