About the Client
The client, a prominent EdTech company based in the United Kingdom, specializes in delivering comprehensive online educational solutions through a robust Learning Management System (LMS).
Request
The client sought to upgrade and enhance their existing LMS system, to improve functionality and security, ensuring a state-of-the-art learning experience for their users.
Company Profile:
Location:
United Kingdom
Size:
550 employees
Industry:
Software Development
Vertical:
Educational Technology (EdTech)
Background:
The company, a leader in EdTech solutions, excels in developing and maintaining learning management systems (LMS). With a focus on quality, the company employs modern software technologies to deliver top-tier educational tools in the global market.
Challenge:
A leading UK-based EdTech provider (550+ employees) relied on a core LMS built on end-of-life technologies (Django 1.6 / Python 2.7). The legacy infrastructure posed critical security vulnerabilities, prevented scalability, and lacked test coverage, making every deployment a high-risk event. They needed a partner capable of refactoring a live, complex system without disrupting thousands of active student users.
Enhancing an LMS System
Audit & Stability:
We first stabilized the existing codebase by writing 5,000+ new unit tests to cover previously untested logic, ensuring zero regression during the upgrade.
The Migration:
Systematically upgraded the core engine to Python 3.10 and Django 3.2, eliminating years of technical debt.
Observability:
Replaced string-based error logging with structured JSON logging, integrating it directly into Google Cloud Platform (GCP) and Grafana for real-time performance monitoring.
Technologies we used
Python
Django
JavaScript
Jquery
Postgresql
Google Cloud Platform
AWS
Implementation Process
UVIK initiated the project by conducting a thorough audit of the existing system, identifying key areas for improvement, especially in security and performance. The implementation process involved:
- Writing nearly 5,000 unit tests to cover previously untested functionalities.
- Upgrading from Python 2.7 and Django 1.6 to Python 3.10 and Django 3.2.
- Integrating new security features like Content Security Policy to protect against unauthorized data breaches.
- Writing nearly 5,000 unit tests to cover previously untested functionalities.
- Upgrading from Python 2.7 and Django 1.6 to Python 3.10 and Django 3.2.
- Integrating new security features like Content Security Policy to protect against unauthorized data breaches.
Results:
System Stability:
Achieved 99.9% test coverage on core modules by implementing 5,000+ automated unit tests, reducing deployment-related bugs by an estimated 80%.
Performance:
The migration to Python 3.10 and query optimization reduced server response times by 50%, directly improving the student user experience.
Security Compliance
Closed 100% of known vulnerabilities associated with Python 2.7, implementing a strict Content Security Policy (CSP) to meet modern EdTech data privacy standards.
Observability:
Reduced Mean Time to Resolution (MTTR) for system errors from hours to minutes using the new Grafana/GCP monitoring dashboards.
Conclusion:
This ongoing project showcases the company's ability to handle complex software upgrades in the EdTech sector. Through the enhancement of the Client’s LMS system, the team has demonstrated proficiency in modernizing legacy systems and implementing advanced security and monitoring solutions. The project, still in the development phase, plans to continue upgrading Django to version 4.2, reflecting the company's commitment to continuous improvement and innovation in educational technology solutions.
