Work History

Senior Software Engineer

WiseTech Global
11.2022 - 07.2025
  • Project Name: CargoWise Customs and Compliance
  • I implemented a message generation tool to automate message creation techniques to increase development cycle efficiency and improve productivity.
  • Create a new microservice to import the tariff data from the customs department website of the country and integrate the modifications into the database without affecting the functionality of the product.
  • I was involved in the design and implementation of various modules (Custom declaration, NCTS, Temporary storage) for Cargowise's custom product to speed deployment to Italy, Poland, Germany, and Norway.

Software Engineer - II

Microsoft
10.2018 - 10.2022
  • Project Name: Kaizala Messaging Application
  • To defend against DoS attacks, a server-side rate limiter based on phone number, IP address, and device ID was designed and put in place.
  • I owned Kaizala features like tenant and user data export, phone number migration, and user log-in sequence.
  • I implemented the receipt message manager for large groups to decrease the message delivery latency for the small, and one-on-one groups.
  • Project Name: Configuration Management System
  • I had combined a CI/CD pipeline with a module that was used to identify and analyze cloud-based service configurations (Public, AirGap) and replace them with tokens. In the cloud, the ECS microservice operating as a seed service subsequently substitutes these tokens with real values. A fresh cloud setup now takes a few days instead of years thanks to this module.
