As a senior developer on the Chargebacks team, I often take on the role of spiking and writing tickets for new projects. I am comfortable running these projects while managing the delegation of tasks and providing technical support to more junior developers on the team.Projects I worked on include: • Worked as lead developer on several parts of our Worldpay partner integration for chargebacks ingestion. This has been a long running project involving the creation of several new partner specific micro services using technologies like Vert.x, Kinesis and gRPC. I have been part of many calls and workshops with developers and product managers at Worldpay to agree and solutionise various parts of the partnership integration • Built an internal Slack notification service backed by a queue to provide real time feedback to Chargeback Investigators during asynchronous batch file uploads in a scalable manner • Developed a new integration testing strategy for the team leveraging our internal integration testing service to mock 3rd party responses. This has greatly improved our ability to test the choreography between multiple micro services • Created a Python scripts in my own time to integrate with the GitHub API to improve the team's productivity by giving real time notifications on Precommit builds failing and code reviewers requesting changes to PRs • Took sole responsibility in creating and executing a Java based interview tailored for a Senior Backend QA role Show less

--- Insights and Reporting Services Team ---I spent my first 7 months at Signifyd working on data engineering tasks IRS team.The primary focus of the IRS team was to build and maintain various ETL pipelines to move data from our live Cassandra database to our Redshift data warehouse which would feed into our reporting tools like Looker.Projects I worked on include: • Upgraded our AWS hosted Looker instances. The result was improved performance for our analysts running Looker reports • Set up a new ETL using Airflow. This ETL extracted data from S3, transformed it to match our Redshift schema, and loaded it to our Datalake tables in Redshift • Added new tables to our Apache Spark ETL written in Scala • Gained experience working with the Talend our legacy data pipeline tool and worked on migrating/retiring ETL jobs from this flow--- Chargeback Services ---After this I moved to the CBS team. The primary goal was to equip our internal Chargeback Investigators team with the best tools and data enabling them to efficiently challenge fraudulent chargebacks and recoup funds lost through wrongfully claimed chargebacks.Projects I worked on include: • Tech lead on project to overhaul our legacy Aftership integration for delivery tracking information. New solution used Vert.x to POST updates to Aftership, webhooks to intercept Aftership updates and a combination of SQS queues and Kinesis subscribers • Overhauled our existing Adyen chargeback ingestor integration to include an SQS queue to ensure resilience and scalability of chargeback ingestion • Built out a new PayPal chargeback integration including customer onboarding flow using OAuth with 3rd party PayPal widget injected in our customer console • Worked with the Slate templating library in our React code to add new and improve existing chargeback dispute templates for our Chargeback Investigators Show less
