Hello, I’m Nikita Karatsev

Development of the Edbee LMS and its on-premise edition in a three-person team. The on-premise edition was actively developed throughout 2025–2026.

Key responsibilities and results

• Architecture design, task decomposition, frontend/backend contract alignment, and code reviews.
• Development of on-premise features including detailed learner analytics, Excel export, groups, agency portals, bulk invitations, and CSS tokens for theming.
• Major frontend refactoring: dependency upgrades, migration from Webpack to Vite and from ESLint to Oxlint, and partial migration of tables to TanStack Table.
• Asynchronous locale dictionary loading and initial extraction of shared components into a Storybook-based UI kit.
• CI/CD setup for frontend and backend repositories in GitLab and subsequent migration to GitVerse: checks, build, semantic release, and automated deployment in about four minutes.
• System deployment to two production servers using Nginx and Docker Compose, plus containerization and handover documentation preparation.
• Jitsi/Jibri infrastructure evolution from bare metal and Docker to Kubernetes/Helm with on-demand recording pods, S3 uploads, and backend metadata delivery.
• Webinar analytics covering attendance and speaking time per participant.
• Use of Feature-Sliced Design for new pages and gradual migration of the project to FSD.

• TypeScript
• React
• CSS Modules
• TanStack Table
• Vite
• NestJS
• PostgreSQL
• TypeORM
• Redis
• S3
• Docker

• Development of components and utilities for the UI kit.
• Contribution to backend task delivery during periods of heavy workload for backend developers.
• Development of a script that synchronized Yandex Tracker tasks with Google Sheets to present project progress.

• Technologies:

• TypeScript
• React
• Redux
• TanStack Table
• Webpack
• Google Apps Script

Frontend development of the TRNR fitness app and interfaces for an employee screening service.

Key responsibilities and results

• Development of an A4 PDF report template with paged.js and email templates.
• Active use of TypeScript throughout the project.
• Development of approximately 81% of the project — 61,661 lines of code, measured with git summary --line.
• Staffscan Lighthouse results: Performance 95, Accessibility 91, Best Practices 100, and SEO 100; successful W3 validation.

• Technologies:

• TypeScript
• React
• HTML
• CSS
• BEM
• paged.js
