Experiences
Sefy
Sefy LTD (Aug 2022 - Present)
- Increased the efficiency of data aggregation by 1000% by automating it with Python Scripts on AWS EC2 Crontab.
- Improved the inefficiency of Many-to-many relationships in DynamoDB by tuning the structure and customising the GraphQL resolvers.
- Accomplished Separation of Concerns by not only managing the global states with React Context but also using Custom Hooks when developing an Admin Dashboard with React, which boosted the performance of collaboration, as well as React Web App.
Themeparkers
Joy Crafters (Mar 2022 - Present)
- Designed and implemented the architecture of the Back End of a mobile application. Developed Client API and Batch Server using Django REST Framework.
- Experienced in designing and deploying an AWS solution including EC2, S3, EBS, ELB, and Auto Scaling Groups. Worked at optimising volumes, and EC2 instances, and separated private and public servers with VPC.
- Used Jenkins with scripts to automate the build and the deployment process, which reduced human error and sped up production processes. Increased the number of downloads by 50% thanks to CI/CD.
Research Assistant
King’s College London (Aug 2021 - Sep 2021)
- The research was about defining the behaviours of abused 3rd party cookies over the websites and simulating them on Graph Transformation (a.k.a. Graph Rewriting) Tool - PORGY.
- Studied the background - OSI Model, TCP/IP Model, HTTP, Cookies, Graph Morphism; and utilised them to build the model - “A Graph-Based Model of the Cookie-Management Process in Web-Browsers”.
- Created new rules to define the 3rd-Party Cookies behaviours and analysed the performance of opting out services, such as Privacy Badger by simulating the model.
Side Projects
E-Commerce Web Design Project
- Improved the Readability and followed Object-Oriented-Programming principles by using Django ORM.
- Built a CI/CD pipeline with Jenkins, which automatically fetches the code from GitHub, tests (Sonarqube), sends notifications (Slack) and delivers (Docker) that helps developers update the code flawlessly.
- Maximised the Flexibility of deployment by containerising the app and dependencies with Docker and Docker-Compose.
