For the latest copy of this resume see: While I am open to part-time consulting and advisory roles, I am not interested in a full-time job. Please do not contact me with job offers.

I am a software technology professional with 25+ years of experience in the industry. I am currently a co-founder and CTO at, where we make software and content that allows employers to assess hard skills of job candidates/employees via various online mechanisms. I am also a founder of, a portal for the tech community in Pune.

I’m on the Advisory Board of Innoviti (a Fintech company in the payments processing space), the Advisory Committee of NIDHI-EIR-PEP and NIDHI-PRAYAS-PC (Govt. of India initiatives in the innovation/incubation space) and a technology consultant at FinIQ (specializing in derivatives and other structured products). I am also an instructor at GenWise teaching high school students courses on diverse topics, including cryptography, game theory, blockchain technologies, critical thinking, and more.

In the past I’ve worked for large companies, and small; I’ve worked in India and in the US; I’ve seen a successful exit, and I’ve seen a dotcom failure; I’ve done product development, and I’ve done research; I’ve written consumer software, and I’ve written enterprise software; and I’ve been a developer, I’ve been an architect, and I’ve been a manager (but hated it).

I am currently interested in tech-enabled education and skills assessment, fintech—including quant finance, bitcoin/blockchain, and payments processing—and machine learning/deep learning. I’m still very much hands-on—I do a lot of programming myself, and I actively keep track of the latest developments in the field.

Veritas (Symantec at that time), Pune, India, Aug 2002–Dec 2007
Roles: Senior Researcher; CTO’s Staff
I was a part of Symantec Research Labs (SRL), which builds prototypes of emerging technologies to determine whether they can be productized. Some of the projects I was involved in: 1) the use of statistical techniques to analyze corporate communications data (i.e. e-mail) for preventing leakage of sensitive data, 2) the use of data-mining algorithms to automatically detect configuration anomalies and other mistakes in large enterprise data-centers, and 3) the application of information retreival algorithms to automatically detect variants in malware samples. In some projects, I had a hands on role where I did everything from the conceptualization and design, to the actual implementation and programming. In other projects, my role was more architectural - setting the direction, guiding the team, resolving conflicts, and evangelizing the idea across the company.

Ph.D. Thesis Research
Dynamic Query Optimization in Database Query Processing:
Designed and implemented Dynamic Re-Optimization, an algorithm that dynamically detects sub-optimality of a query execution plan during query execution and improves performance by re-optimizing the query. Statistics are collected at key points during the execution of a complex query, and are then used to optimize the execution of the query, either by improving the resource allocation for that query, or by changing the execution plan for the remainder of the query. To ensure that this does not significantly slow down the normal execution of a query, the Query Optimizer carefully chooses what statistics to collect, when to collect them, and the circumstances under which to re-optimize the query.

Extensible Query Optimization:
Designed and Implemented OPT++, a tool that uses an object-oriented design to simplify the task of implementing, extending, and modifying an optimizer. Building an optimizer using OPT++ makes it easy to extend the query algebra (to incorporate new query algebra operators and physical implementation algorithms in the optimizer), easy to change the search space explored, and also easy to change the search strategy used. Furthermore, OPT++ comes equipped with a number of optimization techniques and search strategies that are available for use by an Optimizer-Implementor. Conducted a performance study that validates the design of OPT++ and shows that in spite of its flexibility, OPT++ can be used to build efficient optimizers.

Query Optimization in Object-Relational Database Systems:
Used OPT++ to implement and study a number of different optimization techniques and search strategies and how they interact with each other. Implemented a number of search strategies including dynamic-programming (System-R style), Simulated Annealing, Iterated Improvement, Two-Phase Optimization, and A*. Implemented a number of optimization techniques to handle join enumeration, expensive predicates, reference-valued attributes, path indexes, set-valued attributes, abstract data-types with methods, and spatial operations. For each optimization technique, studied how effective it is, and how it is affected by the choice of search strategy.

Other Activities

Websites and online communities, 1995–present
As a hobby, over the years, I have created and maintained various websites and online communities. This has helped me get a very good understanding of how the web works, and of growing and nurturing websites and online communities. This understanding has been very helpful for me in my current and past jobs, and I believe will be increasingly important as time goes on.
