Experience
SFA Web-based App
A web-based app for sales management, using sales agents. I was involved in all stages and all levels of project development, including business analysis, technical documentation, application architecture, cloud infrastructure architecture, database structure, and web app development. I also helped my client implement a new client allocation for agents, which increased the number of clients served by an agent.
Hybrid Cloud Infrastructure
A hybrid cloud approach I implemented to split the existing application infrastructure to host the application in Azure App Service and keep the database on the client's internal infrastructure. The connection between the client's internal network and the Azure infrastructure was done using a VPN Gateway.
Sales Process Management Application
The client needed an experienced lead developer to define the technical approach, architecture, implementation plan, and other technical requirements they needed. Based on the client's requirements, their technical team experience, and their familiarity with the Microsoft development frameworks, I decided to use Blazor for the Web UI, C# and .NET for the server-side, Azure SQL as the database, Azure Blob Storage for documents storage, and Azure Functions for the daily background tasks.
The cloud services were chosen based on the client's request and preference. Blazor was selected because it provides rich UI components to help build responsive and attractive user interfaces. These built-in security features help protect the application from common web application vulnerabilities like cross-site scripting (XSS) and cross-site request forgery (CSRF) and the possibility to share code between the server and client-side.
