As a DevOps and Fullstack Django Developer, I started working on that project and latter joined my colleagues for developing, deploy, and maintain the existing code base and one major of the work was optimizing performance and einsure that the app is allways operational. One signifincant achivement was optimizing an analytical page from 4 minutes to 500-800 by using a customised cache system and reducing sql queries. Key contributions included: - Implement caching system for optimizing a page load from 4 minutes to 500-800 milliseconds. - Reducing database queries by profiling n+1 select issues and unecessary nested loops. - Resolving existing bug and deployment issues. - Automate SSL certificate renewal as it cause a problem to client/users before - Develop new UI for new features that the client requested.
