ExpressNodeReactTypeScriptAmazon Web Services (AWS)

As a developer lead at Allegro Credit, I own the end-to-end delivery of multiple applications, including the full-stack modernization of a high-performance React/Node.js payment portal. Following a critical project pivot, I assumed sole development ownership of a mission-critical API proxy, engineering a production-ready solution within a strict one-month deadline. Beyond architecting high-availability systems, I direct a small team of developers, maintaining high standards through rigorous code reviews, Lighthouse accessibility compliance, and the integration of GitHub Copilot to optimize development velocity. My role bridges technical strategy and execution, serving as the primary lead for production-critical issues and collaborating directly with senior leadership to ensure technical excellence across the SDLC.

I engineered a comprehensive Next.js/React healthcare platform designed to connect cancer patients with clinical trials and specialists through geospatial visualization and high-performance real-time filtering. To ensure secure and scalable operations, I implemented an AWS Amplify/Cognito authentication system integrated with SES and Lambda for serverless transactional processing, while managing complex patient profiles and multi-step pre-screening workflows via Redux Toolkit and robust Formik/Yup validation. By prioritizing performance and reliability, I achieved optimal Core Web Vitals through server-side rendering and established a rigorous quality framework utilizing Cypress for end-to-end testing and ESLint for code standards.
