Experience

A Mobile App for 8,000 Salespeople

I developed an Android application in the early 2010s as a part of a five-person team, where a sales team entered about 200,000 orders daily. This app synchronized over the internet and had close to zero bugs and downtime, mainly due to around 95% unit test coverage. I used Jenkins for code compilation and some plugins for code coverage and other metrics.

A Web Application to Register Farmers as Certified Growers

An Angular-based application using PowerBI web reports. I was the lead architect and developer, charged with coding the front-end PoweBI integration and most of the back-end C# .NET APIs communicating with Microsoft CRM Dynamics APIs to store data and SharePoint to manage files uploaded by users. I was responsible for the architecture, including the discussion with the client and other stakeholders, with clear diagrams and documentation. I managed the implementation of Azure cloud components, including Azure app service, storage account, app insights, Azure AAD app registration (service principal) etc. I led a team of two developers, the authentication and authorization using OAuth 2 client credentials and authorization code and the implementation of cloud configuration and application code to validate JWT.
