I'm making Lambda the best compute service in the world. Come join me!

► Defined the metrics, roadmap, and tracking mechanisms to lead several teams to deliver hundreds of millions in cost savings for AWS. Projects included ML-based traffic prediction, placement algorithm optimization, and customer demand shaping.► Designed and led a project to decouple Lambda control and data planes through scale inversion via a new microservice. The project involved 7 teams, improved cold start availability by ~1%, and made customer-facing Get* APIs easier to reason about.► Found and fixed a bug in a library that cost 10% of CPU of the main Lambda fleet through a low-level deep dive.► Mentored several engineers through promotion and became an interview bar raiser.

► Launched the back-end for Skill Evaluation by extending the evaluation system I designed and simplifying the proposed architecture.► Led the migration to EC2 autoscaling, cutting costs by 50%.

► Architected, built, and led a team of 8 to deliver a machine learning platform that reduced the time to evaluate Alexa ML models by 2 orders of magnitude.► Evaluated bloom filters for use in training and recognition of Alexa Skills.

► Architected and built a global, distributed replication system to serve author metadata in 11 marketplaces. Scala, SQS, DynamoDB► Developed a middle-layer HTTP router to proxy front end requests to self-documenting back-end microservices. Java, Scala, Swagger► Designed and built an elegant UI empowering authors to maintain their biographies and profile images across Amazon marketplaces throughout the world. React, REST, DynamoDB

► Launched a redesign of Author Pages on Amazon.com, handling hundreds of TPS. Java, JavaScript, Spring MVC► Stood up the back-end REST service to a customer-facing site. Scala, Spring WS► Led migrations to AWS with no production incidents. RDS, EC2, DynamoDB

► Architected a near real-time billing automation system handling $25 million in transactions per day. Led the team of 6 to complete the long-stagnated project on time and within budget. C#, WCF, SQL► Created a graphical data analytics tool used by sales, product development, and client services to compare programs across key metrics, cutting program costs by 25%. C#, WCF, Silverlight, Dynamic SQL► Crafted an application-wide solution to address cross-site scripting and authentication vulnerabilities in a cardholder-facing web application handling 10,000 visitors per day. Java, Struts, Spring

► Merged the loan origination and collection systems of First Tech and Addison Avenue. Completed the integration for a demanding client with zero production issues. SQL Server, VB.Net, Ext.js► Developed a real-time interface to update and retrieve account information in a robust and fault-tolerant manner for the largest credit union banking system. WCF, VB.Net
