project to integration in order to map the same state on both sides.
Project: US-based Financial company.
Description: The project is a web application that provides accounting software for law
firms. I have worked with third-party API integration, and implemented end-to-end(UI,
front-end side, back-end side, field mapping) CSV import from several other services to
our product - client wanted to complete this task in 4 months (1 month for 1 import type) I
was able to complete all 4 types in 2 months. Also, I helped our DevOps engineer with
docker and AWS to simplify project cloud transfer from Google Cloud to AWS.
Project: EU-based mental-health company.
Description: The project was a Slack bot for building strong teams by facilitating
meaningful conversations between co-workers. My area of responsibility was to communicate with the Slack bot API (receive messages, build messages, send messages).
I re-wrote all code related to “build message” logic so that we could use the new version of Slack bot API features, and re-wrote all validation logic.
We used microservices architecture with a proxy server. On this project we had Trailblazer, it was a
little bit hard to work with it and ActiveAdmin. I was responsible for writing DB Views via scenic to
generate big reports and also was responsible for deploying project to AWS via Docker and Terraform.
