TEQ is a Norwegian service that provides transportation services throughout Europe. This project is based on microservices and developed in Python, Django, and the Django REST framework.

I developed significant features using Python, Django, and Django REST framework, co-led a team that migrated a monolithic architecture to microservices using Django and Go, and managed a back-end core team that increased revenue by 40%. Also, I designed and headed the internationalization service enabling the product to go live worldwide and acquire partnerships in Sweden and Finland. Finally, I optimized the system's performance by 70%, fixed critical security issues, led a production-release team, acted as a scrum master for more than ten sprints, and developed and refactored the mobile app back end, increasing the app performance by 70%.

A Django and Django REST framework-based web app. This project creates a common platform for job seekers and recruiters to facilitate finding suitable jobs.

As a full-stack engineer, I have developed most core features from scratch. I've built a resume builder so that candidates can make their resumes. Also, I've designed and developed a website for recruiters and a job recommendation service using Apache Solr and TellusR to recommend more than 1,000 jobs per candidate. Finally, I introduced microservices architecture to increase the system performance. I temporarily worked as the DevOps person to deploy new services using Docker, Nginx, and AWS EC2 and handled all product releases.

A French website for creative story writers who write blog series containing several episodes. Users can give stars and comments on episodes. Users can also subscribe to the series in order to get private access to the private episodes.
I designed and developed the back-end service using Python, Django, and Django REST framework. Designed the subscription service using Python, Django, and Stripe. Implemented caching mechanism using Redis, which increased the system performance.

DNN is a project which helps the Danish police investigate drug dealers. This web application comprises Python, Django, the Django REST framework, Vue, PostgreSQL, and AWS. I was the only back-end developer to work on freelance projects. In this project, I was responsible for designing all the features from scratch, providing API to the front-end service, designing the database layer, and handling system design so that the back-end service could handle millions of requests/minutes. I have designed the optimal route recommendation feature using Google Maps directions API, which creates optimal routes for the police daily based on their assigned cases. I have designed the authentication system, providing JWT Token, and
I have designed custom role-based authorization to secure all the endpoints.
To generate case files as word documents, I have used the python-docx library.
For deployment purposes, I have Dockerised the whole application.
