I was in charge of several important projects. The system was based on C#, ASP.NET Core, NodeJs, MSSQL and IIS server.

Accomplishments include

  • Integration between ERP and B2B systems using Restful API | Back-End
    • The backend of our ERP system was not designed as RESTful API. So, I developed some parts of ERP system which needed to be integrated with the B2B shopping website.
    • When I communicated with developers of B2B system, we referred the Integration-logic-diagram which I drew.
    • Changed design pattern from MVC to RESTful API for the Integration between systems.
This is one of the Integration Diagrams that I drew in the progress
I used ‘SwaggerHub’ for the documentation of API
  • Leading a system migration from an on-prem to AWS
    • I developed a scalable serverless system using S3 and Lambda.
    • I designed a network architecture using VPC, Subnets, Route table, and a Load Balancer.
    • I designed a failover, auto-healing, and auto-scaling functionalities.
I sketched the system before adjusting this to AWS server
I drew this using Tool
  • Setting up new ERP system to other IIS server | Full Stack
    • I installed the winCE based program to scanners . The winCE program was linked to webservice with SOAP. I deployed the webservice, ERP system on one of servers. The webservice is linked to a database and the database was linked to the ERP system.
