SUMMARY:

• I have 19 years of technical development experience in the delivery of Enterprise level, highly available, scalable and robust distributed applications.
• Expert level command over MVC, MVVM. If the need of the hour is browser based Applications then I can deliver with technologies like ASP.NET (MVC, Ajax, JQuery, JQuery UI, Knockout, Angular, Bootstrap, Amplify etc.)
• Experience with Cloud based NOSQL data Stores ( DynamoDB, Couchbase, DocumentDB )
• For the server side, I have architected highly available cloud based APIs (WCF / Web API) with Windows Azure /AWS
• Be it implementing an Enterprise Service Bus based architecture (Message Queue based), a CQRS based design or even low level socket programing, I can deliver. I am very comfortable writing multi - threaded socket based networking applications (Windows Services) and equally comfortable building distributed SOA based systems that need to deal with high volume and scale
• Expert level command over XAML based UI Development (UWP / WPF )
• I am SQL Server certified (Stored procedures, functions, triggers, complex queries) and if required can perform reporting (SSRS) and ETL ( SSIS )
• Experience with Embedded systems, Mobile / Tablet based development
• My industry experience includes Telecom, E-commerce, Online Gaming, POS, Healthcare, Construction and embedded systems.
• Designing architecturally sound middle tier components, using (GOF) design patterns and S.O.L.I.D principles is my specialty
• Experience has aided me in architecting and designing systems that are technologically agnostic with an emphasis on open standards.
• On several occasions, I have been involved right from the prototype stage all the way to supporting a system with millions of users.
• In addition to strong technical skills, I am a team player with good communication skills and if required, I can do end to end development as a one man army.
