OpenedX Deployment

This Open edX deployment project involved end-to-end implementation of a scalable open-source learning management system. Starting from a clean Ubuntu server install, I configured essential security layers (firewalls, DNS, SSL) and deployed Open edX using Docker. Beyond deployment, I customized the platform extensively—modifying the frontend and backend via a GitHub fork of the brand-edx-platform repo. Custom features like enhanced course navigation, branding integration, and user interface tweaks were implemented, transforming the platform into a production-ready, user-centric LMS tailored to organizational needs.

Docmost Deployment

Docmost was deployed as a private knowledge and productivity platform to replace cloud-based tools like Notion. I installed and configured the service on an existing Ubuntu server using Docker, securing it with firewall rules, domain-based HTTPS access, and persistent storage. The platform now serves as a centralized hub for documentation, planning, and project tracking. Its self-hosted nature ensures data privacy and full administrative control. I customized workspace settings, optimized performance, and integrated it into my daily workflow for personal knowledge management and internal team collaboration.
