Project Modernization

Led the migration of legacy ASP.NET Web Forms applications to Angular and ASP.NET Core Web API

Tech Stack Migration - Process milestones

• Evaluated Technical Stacks: Conducted multiple Proofs of Concept (POCs) to determine the optimal technical stack for the new system, aligning with organizational goals.
• UI/UX & Feature Alignment: Collaborated with UX and Product teams on control selection and feature implementation through structured POCs.
• Core Framework Implementation: Built foundational features using the new stack, including:
  • JWT-based authentication
  • Angular and .NET Core integration via Interceptors and Middleware
• Architecture Review & Approval: Led iterative technical and design reviews with the architecture team until consensus was reached on the enterprise solution.
• Feature Rollout: Successfully implemented the first major feature (User Page) alongside dynamic navigation (mega-menu and side navigation).
• Knowledge Transfer & Leadership: Conducted solution reviews, KT sessions, and guided cross-functional teams on implementation best practices.
• Modular & Scalable Design: Partnered with Product and Business teams to decompose business logic into lazy-loaded modules, paving the way for microservices.
• Modern Architecture Adoption: Spearheaded Domain-Driven Design (DDD) and event-driven architecture using Azure Service Bus, alongside Minimal APIs for microservices.
• API Gateway & Health Monitoring: Configured Ocelot for API routing and implemented health checks using EF Core’s health-check library.
• Agile Transformation: Championed iterative PMP/Agile practices, training dev teams on Scrum, Jira workflows, code reviews, and sprint ceremonies.

Additional Technical Contributions

• Unit Testing & TDD: Introduced a robust unit testing framework using xUnit, Moq, and Fluent Assertions, enforcing Test-Driven Development (TDD) principles.
• Automated UI Testing: Developed a Selenium WebDriver test suite for critical user flows, implementing a custom reusable framework to streamline control logic.
• DevOps & Branching Strategy: Restructured the branching strategy to align with CI/CD best practices and migrated version control from TFS to Git (Azure DevOps).
• CI/CD Pipeline Optimization:
  • Auto-triggering builds on code pushes
  • Approval workflows and branch policies for secure deployments
• Centralized Logging & Monitoring: Enhanced error tracking by implementing structured logging with Serilog and Azure Cosmos DB, reducing debugging time.
