TECHNICAL SKILLS:

• C#, Java, JavaScript, JQuery, Cloud Computing, Amazon Web Services (AWS), Deployment & Infrastructure, Windows Azure IAAS and PAAS (Web and Worker roles), Hyper - V, Distributed Applications,
• Data Structures and Algorithms, Design Patterns, UML, Customer Focus, Service Oriented Architecture, REST, PowerShell, UI development, Automating testing, Test Plan, Distributed Systems.

PROFESSIONAL EXPERIENCE:

Software Development Engineer

Confidential

Responsibilities:

• Completely automated build and deployment into Amazon (AWS) cloud based infrastructure. PowerShell scripts and AWS .NET SDK were used for this purpose.
• Redesigned and coded cloud based .NET services to bring down memory footprint from > 12 GB to < 1GB under peak load. This was achieved by making it possible to release objects soon after they were not needed and freeing up memory, using asynchronous (C# async-await) pattern, improving scheduling logic and better thread management in the process.
• Wrote or improved processors for digesting data files in various file formats including HL7 format.
• Enhanced test coverage of processors by adding unit tests, setting up a separate test environment where pre-release can be deployed in a production like cloud infrastructure.
• As a stretch project built a real time dashboard using Nodejs and socket.io that shows messages in RabbitMQ as they are received. I used this internally to observe service performance.
