● Led a diverse team of 35 engineers, encompassing multiple disciplines across several functional teams, focused on EarnIn’s core systems and products (moving money, estimating wages, storage and retrieval of bank transactions, customer support tooling, etc.)● Worked closely with recruiting and other engineer leaders to further improve the interviewing process and candidate experience, leading to us filling all our staff and higher roles. This included interview rubrics, shadow and reverse-shadow training, and improved debrief and scorecard rigor● Partnered closely with product to work on product and engineering initiatives to reduce the number of customers contacting support by half in 9 months, saving the company over $2 million annually in support staffing costs● Created and led a weekly operational review for our systems with all of engineering management and leadership in attendance as part of an operational excellence push. This led to several other initiatives that focused on improving the quality of our systems, some of which include: incident reduction, test coverage of 80%, and driving out of SLA vulnerability management tickets to zero● Core member of our architectural group providing guidance on technology choices and patterns and feedback on software designs● Grew and stabilized several teams that were in constant fire-fighting mode into strong, productive teams that now focus on their roadmap by hiring strong leaders and prioritizing operational excellence and system hygiene until unplanned work was the exception, not the rule

● Led a revamped hiring process by creating interview questions to thoroughly test engineers (systemdesign, debugging, requirements gathering, algorithms, etc.) and trained the team on how to perform these interviews to maximize both company and candidate satisfaction. As part of this, started a new grad hiring pipeline which led to filling 8 open roles in 6 weeks● Identified a gap in the way business events flowed from the application to marketing platforms so educated the company, negotiated with the vendor, and led my team in the implementation of both Segment and Amplitude● Conceived of and organized a company-wide orientation/training video program which involved subject matter experts creating 5-minute videos on various topics related to employment at EarnIn and EarnIn’s systems. This greatly helped standardize the onboarding experience● Led a rewrite of our in-house admin tool that required a team of 10 to maintain to the use of a low-code solution (Retool) and an API-based backend that only required 2 engineers to maintain● Led the implementation of a chatbot that reduced customer contacts requiring human support by 15% without reducing CSAT
