Software Engineer

Responsibilities:

• Three tier application(web, application and Database) provisioned in AWS public cloud.
• All the user requests are front-ended by the Nginx Web Server for scalability. These requests are sent to the Application server (Python web application), the application server communicates to the Database to write or read the information.
• Web Tier: The web server is based on Nginx configured on RedHat 7.0 server VM.
• Application Tier: Python based application web server based on Flask framework. This server is instantiated on Redhat 7.0.
• Database Tier: The backend database is MySQL implemented on AWS RDS.
• The Admin of the portal can create/delete/modify users and their privileges through REST API calls.
• Users after successful authentication have privileges to access specific resources. Users cannot create or delete the content in the Database.
• Git hub is used as secured/trusted repository and the source code is pushed to this repository.
• Deployment: Various AWS services are utilized to deploy this service such as, Virtual Private cloud (VPC), VPC networking, Elastic Load Balancers, Route53, EC2, Security Groups, Auto-scaling, CloudWatch and S3, RDS.
• Packer: This tool is used creating different AMI images used for this service. The source code, required packages and their dependencies are part of the image building process on Redhat 7.0 Base image.
• Terraform: This tool is used to automatically deploy the service stack in the specified AWS region. Ansible is used to pass the user data at the time of bringing up the Virtual machines.

Environment: Python, Flask framework, WTforms, Jinja2 templet, Bootstrap, Nginx, MySQL. AWS services (VPC, Elastic Load Balancers, Route53, EC2, RDS, Security Groups, Auto-scaling, CloudWatch and S3).
