Implement features
I successfully implemented the onboarding flow for our credit card services, integrating with several third-party APIs, sending files using FTP, generating contracts from user data and templates provided by the business department, and signing contracts using the digital signature API from FPT Esign. To enable better monitoring of our services, I also exported custom metrics, in addition to the metrics provided by go-prometheus.
I designed and implemented the onboarding flow for our Driverlending service, which involved writing an API to integrate with Be and using JWT for authentication. To ensure efficient database performance, I designed a DB system that indexes the necessary fields for effective query times.
Refactor
I refactor our old investment service to support investing in multiple funds and handle API updates from Dragon Capital. Additionally, I implemented logging for every request made to external APIs to facilitate troubleshooting, set up a cron job for retrieving data from our partner, and export the required data for the BA team.
Unit test
During my time at Cake, I was responsible for developing and maintaining various software applications. One of my key contributions was in the area of testing, where I wrote unit tests using the Testify and Mockery framework to ensure the quality and reliability of our code. I was responsible for exporting tracing data using OpenTelemetry, which helped us to identify and diagnose performance issues in our applications. Add custom middleware for Grpc server to avoid context cancel.
Overall, my work at Cake helped to improve the quality and reliability of our software, and I am proud of the contributions I made to the team.
