About Me:

I’m a researcher at heart and software engineer in practice with several years of experience leading software engineering teams in successful and impactful projects. I pride myself in delivering results, and driving innovation in organizations, as well as improving engineering and buisiness process to enable developer productivity and the org as a whole.

I have a PhD in Computer Science from Columbia University, where I worked at the Programming Systems Laboratory with Prof. Gail Kaiser. My research interests span data analytics, big data, stream processing, distributed systems, large scale system debugging, and program analysis. I have briefly also worked on cloud computing and software defined networking.

Work History:

Currently I work as a Principal Engineer at Priceline in Flights Backend Infrastructure Group, effectively as one of two Group Tech Leads for 4-6 scrum teams. I drive best-practices, architect and drive changes across the Flights Stack, along with representing the team in company wide endavors (moving to GKE etc.). Before this, I worked as a Senior IC at Dropbox, New York with the Previews Infrastructure Services Team. The preview-infrastructure team provides middle layer services to convert uploaded files into previewable content for all user-facing frontends for dropbox (this is the second largest infra fleet after storage at dropbox). I was a researcher at NEC Labs America, Princeton, NJ where I worked with Systems Research Group (formerly a part of the Autonomic Computing Group). I have also briefly interned as Business Analyst at McKinsey & Co., New York in 2008. In my undergrad years, I interned as a Research Consultant at Instituto de Soldedura Equalidade (Lisbon, Portugal), a research organization under the aegis of the European Union where I was involved in a Project called “Natrualhy”. I was also a Research Assistant at the Indian Institute of Technology (Delhi, India) in the Computer Integrated Manufacturing Lab, where I worked on Supply Chain Management.
