• Accomplished main mission of integrating TalentShare team and technology into The Muse in 9 months.• Migrated the TalentShare technology that was acquired into the Muse's ecosystem, conducted research discussions with Muse customers and conceived of and implemented a product built on the technology that aligned with the Muse's value proposition, rolling all of this out to customers within one quarter.• Rebuilt the Data team to focus primarily on recommendations and personalization both through hiring new team members and refocusing the work of the team.• Led the team in the development of a series of recommendation algorithms and their implementation into the consumer-facing applications as both engineering manager and product manager, creating a path that moved the Muse's users from content to relevant job listings. Most of these algorithms were new to the product but those that were able to be A/B tested saw 50%+ improvements in click through rate over the prior versions.

In the course of leading product and engineering for TalentShare, I envisioned and wrote product specifications and wireframes for the TalentShare product, drove and contributed to the execution of its development, and ensured it met a high bar of quality from both a functional and user experience perspective. I then took the product and technology we'd created and developed relationships with the founders and executives of the Muse, leading to our acquisition by them in 2018.During my time with TalentShare, my responsibilities and accomplishments included:• Conceived and built a product that communicates with candidates about the status of their applications for jobs at our partner companies, converting new users to be active within our system at a blended rate of over 25%, while routinely receiving unsolicited positive feedback.• Developed API integrations with 7 of the top Applicant Tracking Systems (ATSes)• Built a recommender system that matches candidates to other jobs. Iterated on the algorithm more than a dozen times to continuously improve both quality and quantity of applications.• Recruited and hired full-stack development and machine learning engineers and established processes to consistently deliver product features on time. Mentored team members to develop their technical acumen and leadership abilities and connected them with meaningful work of interest to them.• Directed UI/UX design contractors in contributing to both the TalentShare product, brand, and marketing website.• Architected and led team in the development of a tech stack that included Node.js, isomorphic React, PostgreSQL, Python, PHP, Objective-C, and React Native while leveraging Amazon web services such as EC2, RDS, Kinesis, S3, SQS, and more.
