  Worked with internal and external resources to scale delivery and development of integrations for SaaS automation and security use cases. I was the architect and team lead for an initiative to reduce and commoditize integrations efforts with new SaaS products. This included re-imagining everything from underlying infrastructure and application structure, to our deployment and scaling process. The prevailing solution has reduced ramp-up time by 600% and delivery time by ~400%. This is the first step in a much larger initiative to truly extending BetterCloud into a Platform and marketplace.

  Worked on a small team to architect, develop, deploy, and socialize BetterCloud's Platform API, the first public API exposed to our customers and tech partners. Extension of BetterCloud's internal Automation functionality and exposure of rich data relationships of customer data across multiple SaaS applications. We leveraged webhooks, a custom scripting environment, and GraphQL to expose the new functionality to the end users. We also followed best practices for injecting sensitive values into webhook configurations and scripts, e.g. username/password and api keys.This project required collaboration with multiple customer and partner facing teams. This included:- Marketing team for launch materials and use cases- Sales and Customer Success for internal training and messaging- Product team for market research and beta socializationStack: Spring Boot, Kafka, REST API, GraphQL, Percona MySQL, ReactJS, Node 6 Show less

  Architected, implemented, and integrated a configuration based Action Engine (AE). Worked with a team of 10 to build and deploy the functionality, then embedded with 5 other teams while integrating the functionality into their systems. Action Engine provides a centralized service with deep integration for interfacing 10 SaaS API's. Actions can be simple REST calls, or a complex series of tasks interfacing many internal and external systems.AE performs executions based on configurations and runtime context. This system reduced the development time for actions from 3 days to 3 hours while reducing infrastructure complexity and cost. Most SaaS API's do not provide batch endpoints, however AE provides common batch functionality for executing actions against sets of entities, or filtered queries.AE operates asynchronously allowing it to scale horizontally and handle back pressure during peak loads. This allowed the execution of approximately 4.6 million actions in 2017, saving our customers ~53k man hours (~4 years) through automation and batch processing in the BetterCloud Core platform.

  BetterCloud Automation:Working on a team focused on automating IT Tasks for multiple SaaS providers. I joined an existing team and have helped expand the functionality so our users can build time saving custom automated "workflows". My latest focus has been providing architecture feedback on new major features while coordinating cross team dependencies.BetterCloud Open Source:Based on observed needs in engineering, I have written two new tools focused on easier management and testing of our use of Apache Kafka. Our internal testing tool has been open sourced on GitHub and I am working to release the monitoring tool soon.Engineering Mentoring:Since my time joining I have researched and socialized Spring Boot frameworks and best practices, cloud architecture patterns, OO design principles (via peer code review), Java 8 features, and Apache Kafka and Avro patterns and best practices. My previous experience at Ga Tech and strong technical knowledge allowed me to become a regular part of the interview process.Technologies: Java 8, Spring Boot, Kafka, Avro, MySQL (JPA), Cassandra, RabbitMQ, Gradle, Nexus, Linux, Git Show less

  Failed Startup: Funding and compensation disagreements, i.e. bootstrapping vs. incubator. Problem: There is a lot of SAT prep software, but not many options for GRE. We aimed to build a custom platform that could leverage AI to provide a customized Test Prep experience for multiple tests, GRE was targeted for MVP. The platform would report on progress, identify and target concepts to calculate ROI between studying for improvements and outcome on test scores, e.g. study "Statistical Mean" for +6 on math section. Post Mortem: I was much more risk adverse than my co-founder. He wanted to quit his job to pursue incubator/Angel funding, while I wanted to bootstrap the project. We did not discover this difference until positive feedback during an Alpha launch and his desire to accelerate. Lesson Learned: communication is important. Responsibilities: Technical co-founder. Full stack development: NodeJS, MeteorJS, MongoDB, Meteor Galaxy Hosting. Show less

  For the past 13 months I have been working with a computational biology group spanning the Mathematics, Biology and Computer Science departments. We are investigating techniques for predicting RNA secondary structures.I implemented a machine learning algorithm using Stochastic Context Free Grammars analyzing subtle characteristics of RNA structure as well as investigating the improvement of other prediction techniques. The project has been supervised by Dr. Heitsch and Dr. Poznanovik from the Math Department and postdotorate fellow Dr. Swenson from Texas A&M. Under their guidance, I was able to build a solid understanding of the biological foundation of the problem, implement prediction algorithms and do a comparative analysis on the results. We are currently transforming the project into a web application and hope to submit the project for publishing summer 2012.Technologies: Java, Machine Learning, HTML, jQuery, High Dimension Data Analysis Show less

The course covers topics including to Linear and Non-Linear Data Structures, Graph Search and Dynamic Programming Algorithms as well as Proper OO design in Java. I participated with fellow TAs to build a youtube clone for TA's at GT (www.Tech-OnDemand.com) and an automated auto-grader. The latter utility used dynamic class loading to reduce 7-15 man hours per week through automation. Show less

A team of 4 graduate students worked to implement an experimental web to mobile service. This conversion exploits industry standards in web development and applies clever algorithms for parsing web content and formatting it to XML. The XML data can be parsed by applications or XSLT scripts can be used to generate mobile specific pages. The group successfully implemented a web service which parses web content and converts the page to an easy to navigate mobile format, including functionality such as handling links and forms.
