About Daniil Frei

I specialize in developing backend web applications on NodeJS platform with NestJS framework on TypeScript language with a sufficient level of typing to keep the code readable and optimal cost-quality! My task is to develop and maintain the server side of a web application using all the best practices that I know from my experience. In most cases, I prefer the REST API approach, with PassportJS or Keycloak-based authentication if SSO and authorization are required - because it saves me time! For DB and ORM, I prefer to use TypeORM and PostgreSQL just because I have experience using it! I know and understand the principles of Express.js but I used it once and the decision to switch to the NestJS framework was very quick! I actively use docker-compose as a container orchestrator for local development. For API documentation, I use the OpenAPI documentation that is generated based on the Swagger plugin for NestJS, and only in case of impossibility or inaccurate description, I describe the scheme myself. In my practice, there was a project that, generated an SDK for the frontend client to speed up development and improve typing and communication between front and back based on the OpenAPI documentation using the "openapi-typescript-codegen" library. I can write a bash or sh script using google search! I usually use Git as a control version system and GitHub to store projects and deploy them to prod with GitHub Actions. On all projects where my development colleagues did not use ESLint, Prettier, pre-commit, and TypeORMs migration - I tried to prove the advantages of these technologies and in some, I was responsible for their implementation! I am open to new challenges and ready to take responsibility for the fulfillment of tasks from senior colleagues. If you have not found a mention of some of the technologies that are required - I will be happy to master them in a short time!

They were based on a gigantic archive of addresses and coordinates of organizations registered in the EU state tax register. I wrote a script that used this huge archive (200 GB of information in CSV format) with the name of the company, its coordinates and address to fill in the fields in the object to test the search! This was a relatively heavy task since the registry was not homogeneous and it had over 200 GB of information in CSV format. In the first approximation, I filtered out the entries that did not suit me and deleted them! Secondly, I sorted the entries by Country and City, which allowed me to split the monolith into smaller files. In the third stage, I wrote a randomizer script that generated business entities and randomly substituted records from different countries and cities that were necessary to create objects for testing. As a result, I wrote 3 scripts that worked with disk space and helped automate routine work (more than 5 thousand unique objects with real addresses and coordinates) that absolutely cannot be done manually!
