Full Stack Developer at Andeshire

January 1, 2025 - Present

Led a full front-end migration from Django Templates to Next.js (TypeScript) + Redux, defining the architecture, patterns, and conventions of the new MERN stack. Designed and built a design system and component architecture (600+ components), organized in Redux by features and slices. Implemented performance optimizations (lazy loading, selective memoization, bundle/code splitting, and selector audits) to reduce load times and improve perceived speed. Developed and orchestrated AI agents to automate recruiting workflows (content generation, analysis, and automated actions), integrating them with existing services. Collaborated on the Django (Python) backend to expose secure, high-performance endpoints, standardizing API contracts and handling front-end data serialization/normalization. Established quality practices: robust state management, error handling, reusable hooks, and PR/code conventions to scale the development team.
