Tech & Team Lead for Twitter’s Developer Platform organization, responsible for building high availability, scalable, and high throughput APIs for external customers.Projects led:- Tech & Team Lead for multiple teams, including the flagship enterprise product. - Tech Lead for Twitter’s Public API Platform. Lead team and platform responsible for rebuilding all of Twitter’s Public APIs. - Worked cross-org to ensure consistency between the Twitter applications, and public APIs.- Rebuilt flagship product (real time streaming APIs) capable of filtering & delivering 1M+ Tweets/second with sub-second latencies between Tweet creation and delivery.- Rapidly prototyped product matching 3rd party data with Twitter data in order to validate market fit.- Built an archive of every Tweet in AWS used to implement a custom hadoop-like map/reduce solution utilizing AWS EC2 spot instances (resulting in a 90% profit-margin product).

Developed high availability and redundant pipelines designed to bend, not break, under spike events. Enriched data flowing through the system with additional metadata in a realtime environment. Using a durable queuing system (Kafka) allowed us to absorb spikes, ensure a 100% deliverable rate, and allow apps to scale horizontally. Utilized in-memory (Redis) and distributed (Cassandra) databases for fast, reliable, and redundant access. Technologies used: Java, Redis, Cassandra, GPB, Kafka, Guice, Guava, ZooKeeper, JUnit, AWS (EC2, S3), Ruby.

Designed and implemented system for upgrading core system components and subsystems robustly and extensibly. Trained junior engineers to solve problems by presenting solutions as opposed to presenting problems. Implemented test frameworks using Ruby and Cucumber to write BDD (Behavior Driven Development) code. Implemented models interfacing with PostgreSQL and REST interfaces. Wrote acceptance tests against 3rd party libraries to ensure software compatibility as releases change. Created mockups of GUI to demonstrate functionality for new development.

Built team of 6 engineers and 4 interns from the ground up with the goal of writing testable, maintainable, and readable code. Mentored junior engineers with regards to best programming practices, done correctly vs done now, problem solving, career advancement opportunities. Identified and tasked senior engineers with system wide problems requiring analysis of benefits and trade-offs. Lead group in three areas, working with support to address their and our customer pain issues, porting code from Windows to Linux, and rewriting large areas of code to be tested, extensible, modular, and readable.

Utilized agile methodologies to test and write code in C++. Introduced modern programming practices such as TDD (Test Driven Development), design patterns, and self-documenting code. Contributed towards the design and initial implementation of a CI (Continuous Integration) build environment to facilitate automated builds. Mentored new engineers in system architecture and best practices. Participated in peer code reviews paying special attention to not just form and function, but also taking the opportunity to learn and ask questions about their area of code and knowledge.

Completing both individual and team-centric projects for state of the art flight visualization and analysis company. In an agile environment, used C# and C++ to read data from simulators and real flight data, perform analysis, and visualize flights in a debrief. Design functional specifications for new features/products. Prototyped new features before implementing to improve final design quality. Performed installations at customer sites and supported customers and support engineers in the field. Wrote in-house test applications for previously untestable applications. Integrated with 3rd party visual systems using the CIGI protocol. Key Achievements:Designed system to handle ten times more data than our application was originally architected for.Implemented complex threading designs to make data processing transparent.Updated UDP & TCP/IP libraries to be more robust and useable. Worked with the government to write functional and design specifications for the contracts.

Completing leading-edge software engineering projects for this $65M Tape Drive Library company with 300 employees. Work independently on projects, programming in dynamic XML with IESimple in WinCE to create user interfaces (UI), managing logical system configurations, motor control, and third-party tape drive interfaces. Write engineering/design specifications, and communicate with up to 10 other engineers working on separate modules to coordinate project completion; review code to reduce bug reports. Resolve escalated bugs, gathering information from field engineers, resolving problems and reporting back to escalation team/management. Deliver presentation/training to test department staff on new features prior to testing. Perform EVT (Engineering Verification Testing) testing code and setting up hardware/software for test bench, running basic tests to ensure software works. Implement C++ wrapper functions to some of the OpenSSL library, and integrated the HiFn compression library into existing data recovery software. Utilize Painless Software Scheduling to estimate completion time for tasks and train staff to better estimate schedules. Report weekly on task status, overhead and issues. As an intern, wrote software, primarily in PERL, for testing products.
