• Program thee world is about helping people do things & focused in productivity space. Homeo Clinics is a must have productivity app & SAAS service for every Homeopathy Practitioner focused on patient note taking experience.
• Envisioned & built the Windows Store app from scratch using WinJS (javascript/HTML/CSS). It included building custom MVC framework (PageControls + Custom Controls + ViewModels) that abstracted the functionality to experience the entities in a Windows Store App. Given the metadata - it enabled to list, search, add, update, delete and navigate the related entities (like clinic, patients, reviews) and was built with long term strategy for rapid development of future apps. The whole UX was built keeping in view user productivity, immersive and fluid experience.
• built from scratch the nodejs based cloud service including oauth authorization, Windows Azure table storage based logging infra, solr based text search index.. It also included building custom entity middle tier framework on top of Windows Azure Table Storage with features like multi-tenancy, user based entity access control, validation, authentication, unit testing infrastructure using mocha - to enable rapid development on top of Windows Table storage (nosql).
• Experiences include bootstrap a startup, technical strategy, service architecture, Agile development, REST api design, OAuth 2.0, mocha, solr, rigorous async programming in nodejs, azure nodejs sdk, MVP, framework development, Metro UI, WinJS , Windows App Store, deep customer connect, scalability, operations.

• Transforms Engine and Visual Studio tooling
• Overview: Enterprise application integration require message transformation. Transforms tools support visual way of expressing the transformation, compiling the transform to workflow activity and transforms engine to execute the transform on incoming message. It includes visual studio designer, integration with visual studio build and errors and format agnostic transform runtime that could handle messages in xml, json format.
• Contribution:
• 1. Identifying and prioritizing all looping patterns and advanced mapping scenarios for XML data (schemas)
• 2. Surfacing concepts of scope and intermediate list data structures (on design surface) to solve mapping of complex looping patterns
• 3. Design and implementation of view model for the mapping designer including incremental validation to surface/dismiss errors in visual studio
• 4. Design and code reviews for the map OM (object model) for the map, its conversion to workflow activity and transform runtime to execute the transform
• 5. Design and code review for the UI (designer) work to surface scope, its collapsibility, pages, bread crumb control to represent scope nesting, cut and paste, highlight error shapes and many nuances to build right user experience for mapping
• 6. Unit test automation and get coverage > 70%
• 7. Lead the dev team through this - closure on requirements, prototyping, design closures, milestone plans, change list mgmt, reporting team status, co-ordinate across feature team etc.
