Skills Summary

Author: Advanced Perl Programming (O'Reilly and Associates), an O'Reilly bestseller and top-10 Amazon book in the computer books section at one time. It played an influential part in the rise of the early Web and e-commerce servers.
In addition to academic experience (below), I have taught month-long distributed systems courses and short-format courses and talks on programming languages, mathematics of PK cryptography, networking and distributed systems at a number of companies and conferences since 1987.
Academic Experience & Research

  • Created and taught "Engineering a Cloud" where UG and PG students wrote fault-tolerant file systems and distributed databases from scratch, including implementing the Raft consensus protocol
  • Co-taught (with Prof. S Sudarshan), "Implementation Technniques in DBMS" for UG and PG students, including an in-depth treatment of Postgres internals.
Industry Experience

  • Design of the next generation of the Universal Payment Interface for the National Payments Corporation of India. UPI is a lynchpin of the Indian economy and already supports upto a billion transactions a day. The present design is a soft-state transaction coordinator between banking systems that handle all the state.
    My task is to design and deliver (a) a stateful transaction coordinator to support mobile-to-bank and mobile-to-mobile transactions and, (b) a robust multi-site active-active system to handle up to 10 billion transactions a day
  • Advisor for National Stock Exchange, Materials and Commodities Exchange. and UIDAI for Aadhar.
  • In-depth architecture reviews for Receivables Exchange of India, Clearing Corporation of India and Indian Railways Passenger Reservation System.
Worked on the Bloom language, a Datalog variant for declarative networking. Restructured, re-implemented the interpreter for performance.
Investigated online database compression. Designed and prototyped parts of a NoSQL database with Sinfonia-style coordination.
Designed, developed and delivered a power-aware secure cryptographic solution for wireless sensors that are embedded in roads and highways. This environment is extremely hostile to electronics, and it is expensive to stop traffic and replace batteries, so power management is key.
Designed & wrote the world's first high-performance Java-based distributed transaction manager (still in production), and the first-ever EJB container. The Weblogic server convinced the world to take Java seriously for the enterprise-server side, especially for transactionally-sensitive data handling.
  • Designed and implemented a Cargo Handling System for Federal Express (now FedEx). This was a large-scale simulaiton with complex constraints to assist planners in optimizing FedEx's aircraft utiliization. Constraints included different metrics for cargo (e.g. by volume for seasonal flowers, by weight for engines from Detroit). The system won the 1999 Computerworld-Smithsonian award for best transportation software.
  • Delivery Confirmation Information System for UPS.
  • Participated in the design of one of the world's earliest commercial CORBA ORBs, and implemented the transactions and concurrency service components.
  • Introduced Python/TCL bindings for the company's core C++ product that made it so usable that the company pivoted to making the scripting language as the main development platform
Wrote firmware for embedded systems (terminals, boarding pass printers), protocol gateways for airlines to connect to airline networks (Galileo, Amadeus)
