Experience
Chatting Buddy
This application utilizes:
• Firebase for authentication, real-time messaging, and storage
• Dialogflow for chatbot functionality
• TensorFlow and other libraries for training mood analysis and recommendation
• Python Flask for serving API requests and Celery for asynchronous tasks
• React for the client application
I handled the front-end development, mood analysis, chatbot back end, and integration with various APIs.
Rent-a-car
This application is built with Python Flask and Ariadne GraphQL, MongoDB, and React and hosted on AWS with autoscaling and load balancing capability.
I was the project's tech lead responsible for prototyping the application, researching for technology stacks, organizing scrum meetings, and mentoring fellow engineers.
Green Building
The application used React and React Native on the client side and Node.js, Spring Boot, MySQL, and MongoDB for the back end. It is hosted in AWS with the capability to auto-scale and load balancing.
I led the effort of architecting the application, developing the front end, mobile client, and admin functionality, collecting and analyzing simulated sensor data, and cloud DevOps.
