About Sai Kishor

I’m a Full Stack.NET Developer with over 5 years of experience in building secure, scalable, and high-performing applications for banking, finance, and enterprise clients. In my most recent role at Key Bank (USA), I worked on a digital banking platform where I built and deployed microservices using ASP.NET Core Web API. These services supported core features like customer onboarding, transaction processing, and loan eligibility. On the frontend, I developed responsive modules using Angular 10, TypeScript, HTML, and Bootstrap. I implemented OAuth2 authentication using Azure AD, handled secure data exchange through RESTful APIs, and used Entity Framework Core with SQL Server for data access. To ensure scalability and security, I containerized services with Docker, managed them using Azure Kubernetes Service (AKS), and routed APIs through Azure API Gateway. I also configured Azure DevOps pipelines for CI/CD and used Application Insights for monitoring. For asynchronous messaging and real-time alerts, I worked with Apache Kafka and RabbitMQ. I performed API testing using Postman and Swagger UI, and wrote unit tests with xUnit and UI tests using Karma and Jasmine. Previously at Tata Consultancy Services, I developed.NET Core APIs and frontends using React, worked on ETL pipelines using SSIS, and handled cloud deployments using AWS Elastic Beanstalk and CodePipeline. Monitoring and debugging were done using AWS CloudWatch and X-Ray. I follow Agile methodologies and use tools like JIRA, Git, and Azure Repos to manage sprints, code reviews, and feature delivery. I believe in writing clean, maintainable code and staying current with new tools and best practices. I’m now looking for full-time opportunities where I can bring my experience, learn from new challenges, and contribute to high-impact projects.

   At Key Bank, I’m working as a Full Stack.NET Developer on a large-scale digital banking platform, where I’ve contributed to the development of core features such as customer onboarding, transaction history, and payment services. I’ve played an active role throughout the Agile SDLC, from planning and development to testing and release, delivering secure, scalable, and high-performing modules.On the backend, I designed and developed microservices using ASP.NET Core Web API, handling key functionalities like account management and transaction processing. I used Entity Framework Core with LINQ and the Repository Pattern for efficient database interactions in SQL Server. I implemented OAuth2 with Azure AD for secure authentication and authorization between internal services.To support real-time event-driven architecture, I integrated RabbitMQ and Apache Kafka for asynchronous communication, particularly for transaction alerts and fraud detection. On the frontend, I developed responsive and interactive interfaces using Angular, TypeScript, HTML, CSS, and Bootstrap, ensuring a smooth user experience across devices.I wrote unit tests using Karma and Jasmine to validate Angular components and improve UI reliability. All APIs and services were deployed to the Azure Cloud Platform using App Services, and further containerized with Docker and managed via Azure Kubernetes Service (AKS) with Helm charts for scaling and orchestration.I managed API traffic and policies using Azure API Gateway, monitored system health through Azure Application Insights, and maintained CI/CD automation using Azure DevOps pipelines. I conducted manual API testing with Postman and documented services using Swagger UI. This role has helped me sharpen my expertise in cloud-native architecture, secure API development, and full stack application delivery in a fast-paced, Agile banking environment.
