...project I've developed is a feature to automatically provision a new server based on weighted specs for disaster recovery or autoscaling.
Employment
Experience
- REST API (Development)
Developed a REST API interface for the RMM suite (RackWare Management Module). Written in Python using Django rest framework.
- Numerous Migration Projects (Development)
Moved many client servers cross data centers and clouds and supported these servers through application testing.
- Numerous Disaster Recovery Projects (Development)
Designed and implemented disaster recovery solutions utilizing the cloud as an HA backup.
- Auto-provisioning Framework (Development)
Designed and implemented the auto-provisioning framework for the cloud migration product. Auto-provisioning makes use of the specs and OS of the source server, and automatically provisions a target server to be as close as possible in the target environment. This framework utilizes APIs to provision servers. It's written in Python leveraging the request lib as well as GraphQL to interface with various clouds' API.
- Cost Estimation Analysis (Development)
I wrote the cost estimation framework for the Hybrid Cloud Management Platform. This feature analyzes the usage data of servers to come up with suggested provisioning models for target servers. These provisioning models were created by the frameworks efficient use of API calls to the selected target environment. The target environment's capabilities as well as cost data were pulled and reorganized into a readable table for the user. This feature had to return very quickly for it should refresh every time the user makes a different selection. The framework was written Python utilizing different libraries to query APIs and make the appropriate calculations.
