  • Design, architect, and implement robust full‑stack application components using .NET Core, C#, ReactJS, TypeScript, Web API, gRPC, Azure SQL, Cosmos DB, .NET Aspire, OpenTelemetry, Kubernetes, and Azure Cloud‑Native Services.
  • Translate functional and non‑functional business requirements into performant software systems.
  • Lead by example in writing clean, well‑documented, and scalable code; contribute to and improve the overall codebase quality.
• Software Design & Architecture
  • Own the design of complex software components and interfaces; produce detailed design documentation.
  • Collaborate with cross‑functional teams to assess functionality, interoperability, and scalability of evolving architecture.
  • Adapt existing architecture to meet changes in requirements and modernize legacy patterns.
• Application Integration & Middleware
  • Identify integration opportunities across internal and external systems using APIs and middleware.
  • Conduct feasibility analysis and implement secure, efficient, API‑level integration across platforms.
  • Troubleshoot and refine cross‑platform interactions, ensuring data consistency and system integrity.
• Emerging Technology & Innovation
  • Stay ahead of technology trends; assess their relevance and viability to solve business challenges.
  • Execute research and POCs to validate new tools and frameworks, influence tech stack decisions.
• Cloud‑Native Engineering
  • Draft and implement cloud deployment specifications based on business use cases, security needs, and scalability targets.
  • Drive infrastructure‑as‑code (IaC) and serverless/cloud‑native practices aligned with Cloud Computing best practices.
• CI/CD & Configuration Management
  • Automate builds, tests, and deployments using Azure DevOps or equivalent CI/CD tools.
  • Configure, test, and troubleshoot multi‑platform deployments, own pipeline architecture, optimization and release governance.
  • Identify and automate repeatable tasks in the release cycle to increase reliability and velocity.
• Product & User Journey Thinking
  • Participate in cross‑functional walkthroughs and requirement gathering for high‑complexity features.
  • Analyze user journey performance, identify bottlenecks, and recommend architectural or code‑level improvements.
  • Bridge product design with engineering execution to ensure user‑centric implementation.
• Testing & Quality Engineering
  • Design and implement manual and automated test cases across integration, system, and performance layers.
  • Define test strategies, write reusable test scripts, and conduct root cause analysis for test failures.
  • Continuously improve test coverage, reliability, and feedback loops within the development lifecycle.
• Project Contribution & Collaboration
  • Lead small to mid‑sized technical initiatives and contribute actively to project planning, estimations, and reviews.
  • Collaborate across teams including Product, QA, DevOps, and UI/UX to ensure successful delivery and technical alignment.
