Dmitrii Kharin

I was responsible for the development of various components of an E-commerce SaaS product, including cashier, CRM and admin panel web applications.

• Leading a team of 4 front-end developers across 3 product teams, including hiring and onboarding 3 developers, conducting approximately 30 interviews.
• Conducting regular one-to-one meetings, performance reviews, and providing support for professional growth.
• Authored documentation for processes, code conventions, and architectural features.
• Initiated regular meetings for all front-end team members, where we discussed new features in the product and explored ways to improve our development approach.
• Conducting assessments of team development tasks.
• Creating a queue of technical debt and addressing it.
• Improved the type system by removing duplicate data interfaces in sections, boosting clarity. Refactored about 40% of the code, resulting in the removal of roughly 1000 unnecessary lines from the average section.
• Improved a section within the admin panel for managing active orders. It updates the list using web sockets and allows users to create tabs with custom filters and sort rules for different scenarios. Additionally, it saves configurations for various tiers, such as Nation level, State level, or Organization level.
• Designed and implemented a marketing scenario constructor in the admin panel. It features step-by-step blocks that connect different relationships, including fork types. Each block contains various options fields and has the capability to append new elements at any point in the chain. All components are rendered on an infinite and draggable area.
• Developed 5 sections with functionality including forms, lists with forms, and nested lists with forms.

Our team of around 30 Engineers actively participated in developing cloud technologies, working on Front-End and Backend For Front-End (Node.js) aspects.

• Wrote comprehensive documentation detailing the deployment of services in cloud architecture, with a focus on security, container registry, and image features. This documentation also included guidance on managing these processes using the TeamCity interface.
• Separated Billing and Support services from the main application, refactored them, organized the deployment pipeline, and launched a preview.
• Enhanced the internal Telegram bot for release management, enabling it to create release/hotfix-candidate branches with new commits, deploy to a staging environment, notify commit authors, collect votes, and prepare for deployment to production.
• Enhanced the i18n run-time library, developed an i18n builder library, and integrated it with CI/CD and an external service for translations. Implemented automated processes involving translation teams and developers. Integrated the i18n framework across 4 teams and 7 services.
• Contributed to the design system's component library.
• Migrated two services from the old internal CI/CD service to the new TeamCity CI/CD service to meet compliance requirements.
• Designed and implemented a popup that prompts users to provide their email or phone number for verification, ensuring its functionality across multiple applications within the navigation panel.
• Developed and released the Front-End part of managed service for GitLab.
• Received an "exceed expectations" assessment twice in a row during performance reviews, a rating given to only 10% of employees.
