    Overview

    TechStyle has become one of the fastest growing e-commerce companies in history. Five portfolio brands, JustFab, ShoeDazzle, Fabletics, Savage X Fenty and FabKids provide over 4 million VIP members with on-trend fashion at an exceptional value

    In a cross-functional role, collaborated with multiple engineering teams to architect, develop and deploy new applications, new features, and enhancements to the company’s e-commerce web applications. 2 daily stand-ups and tickets on multiple Jira sprint boards.

    Platform Scaling Strategy

    Architected pricing experimentation infrastructure supporting TechStyle’s portfolio brands, enabling high-traffic multivariate testing across millions of VIP subscribers.

    The Challenge

    Needed a scalable way to test pricing strategies across 4M+ monthly subscribers without impacting core e-commerce performance.

    The Solution

    As part of a two-engineer team, designed and built TypeScript microservices for multivariate pricing tests, integrated into the existing API layer and deployed for peak traffic reliability.

    The Result

    $250K revenue lift in 3 days. Successfully handled peak traffic across multiple global brands. Established scalable experimentation framework for ongoing optimization.

    E-Commerce Checkout Optimization

    Modernized Fabletics’ legacy checkout system, replacing a monolith with a scalable API-driven architecture to reduce lost sales and improve deployment reliability.

    The Challenge

    Checkout timeouts and legacy monolithic infrastructure were causing revenue loss and limiting feature velocity on a high-traffic subscription e-commerce platform

    The Solution

    Architected Fabletics’ first API-driven checkout. Introduced resilient error handling to recover failed transactions and implemented automated testing to stabilize deployments.

    The Result

    $26,000 in incremental revenue generated within the first 48 hours of deployment. Reduced checkout timeouts and improved transaction reliability. Established foundation for SPA migration across brands.

    "Stephanie has a heart of gold and an ability to blaze through heavy workloads with precision. She helped to maintain and add to the internal APIs and add frontend or backend code; focusing on Typescript, JavaScript, and React. Stephanie works to understand and adapt to help her team and company succeed. In my time with her, we'd come to each other for advice on how to handle certain areas of the code base while maintaining each team's ideals. She's be a delight to work with, and any company would be thrilled to have her as part of their team!"
