ReedsySenior Frontend Developer

Nov. 2019 - Jul. 2023United KingdomSince Nov 2019, I have been involved in a number of key projects. In my initial role, I worked primarily on the Reedsy Discovery application, where I was responsible for implementing new features and designing an effective, simple, and easy-to-use interface. During my time working on Reedsy Discovery, I was able to integrate Goodreads into the user's library. Also I integrated Typeform into the Discovery blog posts, which allowed my colleagues to add quizzes. I also upgraded the PageSpeed scores for the blog posts from an average of 20 to 90 and reduced the initial page loading time from 10 seconds to less than 1 second on avg. In addition, I optimized the mobile UX and cross-browser styling and logic, improved SEO and performance of the blog pages, and added new features such as 'Add-to-library' or 'Buy book' to the blog posts. Furthermore, I created and implemented a way of tracking user activity to help understand user behavior and implemented a dependency updates flow for frontend libraries, improving CI configurations, which saved time for testing. One of my most notable achievements during my time at Reedsy was creating the new version of the Editor tool. This involved implementing a complex layout with various assets and widgets, creating the UI for the document history mode, and developing a number of widgets providing extra customizable features for mobile, tablet, and desktop users. Currently, I am leading the development of a major add-on to the Editor - a book outlining, planning, and world-building tool. The public beta version of this add-on provides the base functionality to create notes, sort and group them, and integrate them with the Editor app.

Distributed outsourcing team Development Team Lead

Jan. 2019 - Jun. 2023-As a team lead for a distributed team of 5 frontend developers, I have been responsible for providing outsourcing frontend development services and overseeing the development of applications. Two examples of these are the «docuForce» and «RM-Keeper» apps. "docuForce," which streamlines document exchange within organizations and with external parties by providing support for various types of electronic signatures. With this system, users can create legally significant documents without the need for paper duplication. "RM-Keeper," provides users with comprehensive tools for managing logistics processes related to physical archival storage, including integrated security and full audit tracing of document activity. By using this system, users can create and manage their archives without having to purchase expensive archive management software. As a team lead, I am responsible for hiring, coordinating, and supporting the development team. I am also responsible for ensuring the quality of the code and product, making architecture decisions. Additionally, I oversee building and automating the development cycle, which has enabled us to work effectively and create stable features with a low level of bugs and issues. Over the years, our team has grown from 1 to 5 developers, and we have implemented several complex applications and mobile applications. These apps required us to design and implement complex solutions for working with digital signatures, processing and displaying large PDF/Excel docs, and building and editing routes for processing electronic documents. We also created our own UI kit and components library and integrated CI/CD processes into our workflow. As a team, our main technical stack includes React, Redux (Thunk), Typescript, Styleguidist, and Flutter. One of our main achievements as a team lead is building the development and testing flow, which has helped us work effectively and create stable features with low levels of bugs and issues.

AitargetSenior Frontend Developer

Nov. 2018 - Nov. 2019Moscow, Russian FederationAs a Senior frontend developer at Aitarget, I had the opportunity to work on innovative projects that helped small businesses automate their advertising efforts on Facebook, Google, and TikTok. One of my first contributions to the team was to conduct code reviews of my colleagues' projects from other teams. I noticed that many team members did not follow core programming principles or test their code properly, resulting in numerous errors. I worked to convince my own team, other teams, and their managers to always run tests before presenting the product to the client, while my code reviews helped improve the situation. After that, I worked to develop the frontend part of a new app. We successfully implemented the MVP of the app in less than a month and I continued to work on implementing new features and improvements while maintaining the app. The main aim of the project was the automation of working with small businesses, helping users create an account and connect ti to their Facebook business page, automatically connecting them to their ad cabinet where they can replenish their balance and generate reporting documents from ad campaigns To help users improve their ad results, I participated in creation an Analyzer app that checked Facebook ads for different criteria and generated a report with pros and cons. It helped users personalize their advertisements by sending them reviews based on several criteria, thus generating an improvement plan. Also, I delivered another app Optimizer, which checked Facebook ad campaigns for different criteria and helped improve them while decreasing spending. Optimizer functioned like Analyzer, but it was more personalized, taking into account the unique features of each business. It offered more detailed solutions, including preventing the ads from competing against themselves. To ensure the stability and quality of these tools, I implemented both unit and E2E tests, and initiated cross-team code reviews.
