- Maintaining the legacy project with C#, ASP.NET, Entity Framework, T-SQL, Stored procedures, and Angular and Blazor.- Fixing bugs and tracking events with debugging tools and implemented the unit testing – xUnit, MSTest, and NUnit.- Utilize MySQL and SQL for managing our voter system, implemented the microservices with using Docker and Kubernetes.- Implemented a RESTful API server with lots of endpoints with entity framework.- Leveraging Azure DevOps for project and development management, version control, and CI/CD. For management, we used Jira and Github.- Developed the project with ASP.NET MVC, and MS SQL for the database.- Built the user-friendly interfaces with Kendo UI and Telerik, and implemented the Angular ENR project for securely managing voter, candidates and all election information.

- Owned multiple microservices and was responsible for the stability of a core project. Built multiple microservices and maintained them.- Implemented the testing features with several platforms such as GrapeJs, Service worker, asynchronous and synchronous integration approaches.- Built multiple demo applications with Angular – user-friendly interfaces with tailwind CSS, storage management with NgRx, async programming with RxJS operations.- Built the API architectures with C#, ASP.NET MVC, and Entity Framework.- Implemented the Azure cloud architecture and built API gateways, serverless functions and assets storage management with Azure API, Azure serverless computing, and Azure blob storage.

- Debugged 20k lines of C# codes to fix a software bug that corrupts transactions of 5800 users: increased customer confidence in the company’s product by 30%.- Developed and delivered the maintenance for 20 .NET websites, using ASP.NET MVC, Angular, jQuery, TypeScript. Achieved 100% client satisfaction and on-time completion.- Turned out 12 software web applications using MS SQL Server, .NET MVC, and Angular to support payroll, HR, talent and performance management applications through system driven approach.- Invented 10 + pocket time clock applications within 14 days of resuming the role using C#, .NET Compact Framework 2.0, and SOAP Web Services.- Built microservice architecture with Docker and Kubernetes.- Conceived and architected an online tool using ASP.NET AJAX Toolkit, ASP.NET 3.5 that enables and allows 50 emergence respondents to get all relevant information and directions to a fire emergency.

- Developed consumer-based features and applications using Python, Django, pyramid, Flask, Web2py, HTML and other web technologies. Designed, developed and integrated a PostgreSQL database of ontological information with a proprietary Scala- based NLP pipeline.- Enabled AWS Data Migration services to fetch the data from Source systems viz Oracle to copy the records which are either inserted or updated on the fly to S3 bucket.- Built reusable and customizable components for the new website using React.JS and React-Routes to create a single page web application.- Worked on Django REST framework as it is much faster to read data and it can be cached. REST allows more formats than SOAP and gives better support for browser clients as it supports JSON. Also, Created templates for page rendering and Django views for the business logic.- Enabled to trigger Lambda Services on top of S3 bucket whenever the file drops from DMS. This Lambda would update the record count in Dynamo DB to have a count of number of files dropped in every group.- Designed and developed web crawler in python using Scrappy framework and using RabbitMQ as a messaging server between the micro services.- Automated Testing Framework has been built to comply with CI/CD pipeline using Nose Test and PyTest also implemented CI/CD pipeline using Jenkins, Ansible Playbooks and Ansible Tower. Created an on premise CI/CD solution using Jenkins and the Pipeline plugin which uses pipeline as code.- Developed a POC using Attunity for fetching files directly from Source Oracle system to Snowflake directly, but which involved a large licensing cost and processing charges.- Used Elastic Container Service and Elastic Kubernetes service as part of Jenkins Job to enable any code changes in repository get reflected to services involved.
