I worked as an architect and principle software developer creating applications for the advertising industry.I was principally tasked with re-writing an existing web application which was written using ASP MVC and using third-party web components. The legacy application was very slow and customization of the components, to meet the product requirements, was difficult.I investigated available technologies and we decided on creating the web application using Angular, Angular Material components and the NgRx library for state management. We decided on creating a GraphQL enabled ASP NET core Web API server for data transfer efficiency.We used a evolving prototype model to develop our products as most of the time our customers were not sure about their requirements. We would demonstrate the evolving software regularly to our clients to ensure correctness and gather new requirements.**Roles and responsibilities:*** Creation of technical specifications based on the functional and non-functional requirements.* Architectural design and documentation of the software and systems.* Implementation and maintenance of the code.* Design, implementation and maintenance of the relational database.* Design, implementation and maintenance of the UI components.* Collaborating with the testing team to resolve software and system defects.

Selpal / SelpalI worked on a small team developing the Selpal web and mobile application.
