Experience
Web Application for Managing Listings
https://modulist.news/I developed a custom-made web application designed to help newspaper owners automate parts of their work. The app's primary purpose was to enable users to create listings (ads, announcements, and more) and submit them for publishing in different newspapers.
The users can see exactly how their listing will look in each newspaper (pixel-perfect) using the newspaper's fonts, font sizes, dimensions, and templates. It has a highly flexible UI for configuring the newspapers that were implemented, including run days, exceptions, deadlines, pricing, and so on.
The front end was built using React, and the back end with Node.js. The app uses Braintree for handling payments. I started as a front-end developer and later continued as a full-stack developer. I was responsible for the production releases, and I worked closely with the clients, helping them plan new features and functionalities.

CRM Web Application
A fully functional CRM system built with .NET MVC and Entity Framework code first. It had all the standard CRM features and some custom integrations with existing internal systems.
I worked as a full-stack developer from the beginning of the app. I was responsible for unit and end-to-end testing (Selenium).

Audio Chat Web Application with Blockchain Integration
A responsive audio chat web application built with React for the front end, Node.js/Express for the back end, and MongoDB for the database. Blockchain was also a big part of the application. We used MetaMask for the login and different APIs, and Web3 for checking users' coin amounts/NFTs to access different special functionalities. Websockets were used for user interactions and for real-time data updates. I built the whole application from scratch, following a premade UI design using Figma. I configured and optimized the hosting environment for all the deployments.
A Wedding Writing Tool
https://www.provenance.co/A React and Node.js-based web app that helps brides, grooms, officiants, and guests prepare their wedding vows, ceremony scripts, and toasts using AI. I was a full-stack developer there and was also heavily involved with maintaining the infrastructure and the CI/CD process. We also added an SSO login, three more apps built with Next.js, and a component library with shared components (using Storybook).
