Software Architect and Project Manager for OpManager OnDemand

Zoho Corporation (formerly AdventNet Inc.)

(Privately Held; Information Technology and Services industry)

July 2006 — September 2008 (2 years 3 months)

- Architect and Project Manager for the next generation Network Management System delivered as a service(SaaS).
- Designed and coded the framework, which uses configurations to run work-flows. Configurations can be provided to extract data using protocol handlers, transform those values using expressions, map it to new or existing rows in database tables and save the unit of work. This work-flow engine was used in every aspect of the product from Discovery, Data-collection, SNMP trap-processing, Event and Alarm Generation, Report generation and more.
- Working with a small team, of just 3 more members, released the Beta version of OpManager OnDemand.
- Kept adding more features in multiple minor and major upgrades, while ensuring minimum downtime, so as not to affect the Beta Customers.
- The design now enables upgrades with zero downtime, since new features are just configuration changes in the database.
Project Manager for OpManager MSP

Zoho Corporation (formerly AdventNet Inc.)

(Privately Held; Information Technology and Services industry)

March 2005 — June 2006 (1 year 4 months)

- Project Manager for a long pending product for remote network management.
- Used the Web NMS RME framework, to come up with distributed management product, with features as in OpManager.
- This product has now branched off as MSPCenterPlus to focus more on MSP features and as OpManager Enterprise Edition targeting large enterprises.
Project Lead, Research Engineer

Zoho Corporation (formerly AdventNet Inc.)

(Privately Held; Information Technology and Services industry)

September 2004 — February 2005 (6 months)

- Responsible for the design and implementation of two experimental projects.
- First, to treat source code as data, by parsing and dumping them into DB. One can query, analyze and modify the data in the DB and then dump it back to file. Modelled the entities involved and completed implementation for Java language and initiated work on VBScript. This was used in SwisSQL suite of products, to migrate database queries in Java source files.
- Second, versioning of data in RDBMS. A unit of data identified by a primary table entity can have dependent data in more tables. Versioning of this unit of data was achieved, by storing the diffs, with a row instance treated as a unit for versioning, which will be tracked when it is inserted, updated or deleted from the data unit. This was also submitted as my dissertation project for MS in BITS.
Project Lead, Prototyping for OpManager NG

Zoho Corporation (formerly AdventNet Inc.)

(Privately Held; Information Technology and Services industry)

August 2004 — August 2004 (1 month)

Project Lead

February 2003 — July 2004 (1 year 6 months)

- Project Lead working with a team of 10 to create a Micro-Kernel (named MicKey), a framework for building RDBMS applications.
- The deliverables included a layer for CRUD of relational data rows using "Unit Of Work" pattern, a layer for Table and Tree views and Multiple Database query and merge. Other orthogonal features like Notifications, Authorization, I18n, Template based Views, Segmentation, Scoping, Cache, etc., were added to conform to the Open-Closed principle using the Interceptor pattern.
- MicKey is now adopted in almost all (new and old) products and services within AdventNet/Zoho.

- Implemented and delivered the new framework, leading a team of developers and QA professionals.
- Parallel work towards the end : Part of a team of two, assigned to identify issues due to multi-threaded operations, in the popular Web NMS 2.3 framework. Came up with a mini testing framework nick-named 'Spinner', which used a work-flow approach to trigger operations on multiple threads. Used technologies like JAXB to load configurations for the operations. This was used to not only identify issues, but to automate those scenarios in regression test setup.
