Gaja comes with an incredible depth of knowledge in the performance tuning of Oracle.  At Model N, we have used other database consultants before.  Gaja, however, was the first that truly used an evidence based approach.  He was able to quickly diagnose root causes and propose effective solutions.  His integrity, professionalism, and communication skills are excellent, giving us full confidence when working with our customers.  Over the past few years, Gaja has been great resource for Model N and a wonderful person to work with.

Gaja's method for getting quickly to the heart of performance problems is elegant, effective and empowering. It can be learned by DBAs of almost any skill and experience level, and requires only an ssh or terminal session to the server in question to be deployed. As a trainer Gaja is clear and authoritative, and makes the process of learning fun and lively. He knows intuitively how to tailor his presentation to his audience, taking time where necessary to clarify any complexities, or speeding on where his audience's knowledge is stronger. As a consultant he is attentive and energetic, and sensitively spreads his enthusiasm throughout the team. The Oracle DBAs at Vattenfall in Berlin highly recommend him!

Rentrak's Box Office Essentials product collects and reports box-office performance data from more than 4,000 theatre locations across North America, and is used by executives from the majority of the motion picture studios in Hollywood. Many of the reports on our web application perform a multitude of advanced calculations on data arriving in real-time. Our requirements for up-time, scalability, and performance are extremely high, and Rentrak approached Gaja to enhance our competitive edge by making our system even faster and more efficient. Within the first few hours of his first day, Gaja made improvements...improvements that our clients could see (445% faster response time).
