I have been working as a frontend and backend developer for 4 years. I am proficient in full-stack development. To date, I have developed different apps for start-ups with combined frontend and backend tech stack. I have hands-on experience of React Js, Node Js, Flask, Django to create fully functional web apps. I have also partially worked on Angular 1x in the early days of development. For deployment of the apps, I have used GCP (Google Cloud Platform) with the help of Docker and Kubernetes. I am also proficient in database design and database architecture. For all apps that I have built, I have designed the database architecture by myself. In the apps, I have used MongoDB and PostgreSQL databases. In MongoDB, I am proficient in complex aggregation queries, replica set set-up, and sharding. While using PostgreSQL I extensively used Extensions, Functions, and Events. Briefing of the recent apps that I have developed will be in the portfolio section. I have built those apps for the clients. I can only show the demo live on the call as per the NDA signed with the clients.
