• Contributed to the development and implementation of a complex big data web application designed to present detailed U.S. Mortgage Security data through an intuitive user interface, using microservices architecture built with C# and Angular.
• Currently involved in building a web application to configure and manage ETL pipelines, utilizing a microservices-based approach with Angular, Python, FastAPI, and AWS SQS.
• Extensive Angular experience encompassing OAuth2 authentication, reactive programming with RxJS, state management using NgRx, feature flag implementation, and rigorous testing practices with Angular component harnesses, Karma, and Jest.

Notable Achievements:

• Designed and implemented a feature enabling users to upload sample data files, allowing the system to automatically infer schemas, flag errors or ambiguous fields, and provide a user-friendly interface for corrections. This significantly streamlined schema creation processes previously reliant on manual migrations.
• Transitioned the authentication system to OAuth2, implemented via a feature flag, enabling seamless switching between the new and legacy authentication systems across different environments.
• Designed and implemented a CI/CD pipeline for monorepo microservices, automatically detecting service-specific changes and triggering respective pipelines. Additionally, the system identifies library changes and proactively executes pipelines for all dependent services, ensuring continuous integration integrity.

I gained practical exposure developing applications using C# and .NET Core. During this internship, I built and deployed a full-stack web application with Angular on the frontend, Spring Boot on the backend, and PostgreSQL for data management. Additionally, I was introduced to DevOps practices, learning the basics of Docker, Kubernetes, TeamCity, Octopus Deploy, and Terraform, and successfully managed deployment pipelines.
