The music-platform project is a web application developed using the Nest.js framework. Its purpose is to offer a platform where music enthusiasts can discover, listen to, and comment on their favorite tracks.
Throughout the development process, I gained valuable experience working with various Nest.js modules and techniques, such as Dependency Injection and the microservice architectural style. Along with this, I solidified my skills in working with MongoDB, TypeScript, and decorators. And in addition, became familiar with using the Axios client for communication between the server and client sides.
Online shop (Express, MongoDB, EJS)
The Online Shop is a web app that lets users browse, search, buy, and merchandise products online, which is built with Express framework, and MVC architecture. It offers user authentication, product catalog, shopping cart, checkout, and order management. MongoDB is used as the primary database, and Mongoose is used as an ODM library.
During the course of working on this project, in addition to my skills in working with Express and structuring code using MVC, as well as using MongoDB with Mongoose, I was able to work with EJS templates, flash middleware and CSRF tokens for user session management, along with services like Stripe for payments and nodemailer for email operations. Additionally, I familiarized myself with the process of preparing an application for deployment, where I utilized tools such as helmet, compression, and used SSL certificates to ensure security.
- Database management: Developed proficiency in working with MongoDB, including using Mongoose as an ODM library for data modeling and interaction.
- TypeScript utilization: Demonstrated skills in using TypeScript and decorators for better code organization and maintainability.
- Client-server communication: Familiarity with handling communication between the server and client sides, utilizing tools like Axios.
- User authentication and session management: Implemented user authentication and managed user sessions using techniques like flash middleware and CSRF tokens.
- External services integration: Successfully integrated external services like Stripe for payments and nodemailer for email operations.
- Deployment preparation: Acquired knowledge of preparing applications for production deployment, including implementing security measures with tools like helmet, compression, and SSL certificates.

Ukraine · Kharkiv · 1 year of experience · Upper-Intermediate ·Published 10 March
At the time I can:
-create responsive, adaptive, dynamic, interactive web-page or SPA
-create back-end Restful API with Node.js, Express or Nest.js with connections to SQL and NoSQL DB, auth.
-deploy app with AWS EC2 or Firebase,Netlify, etc.
Now I have been using TypeScript for development since the middle of 2023.
For now, I have study projects in my portfolio. Currently, I`m working on a full-stack pet project using TS, Express, Mongoose, React, and JWT. Its goal is mostly to practice and create a custom admin app that will accumulate orders from different landing pages. In the future, I gonna add there emails for statuses of orders, live chat for managers and clients, and different dashboards for summarizing orders and other data.
Also, I wanna practice ServerSideRendering and microservices, and serverless.
Here I find out how to read someone's code and look out for bugs left by someone. While I do the main task I look at all that matters, and one time I found too many requests had been sent from the front to back and from the back to the database. That`s why changing page props makes the page long unavailable, it`s about for 10s.
I can say that my main achievement in development at the moment is to learn and understant how works web development, how to look up for solution of a bug or a problem.
