Alex Mesarosh

I’m a Frontend engineer with 15+ years building web platforms, reusable component systems, and CMS-integrated digital experiences for agency and enterprise clients. I focus on strong frontend architecture, reusable UI patterns, and cross-functional delivery that aligns Design, UX, QA, Product, and client stakeholders.

Since June 2021, I’ve led the migration and technical architecture transitioning client web products to React / Next.js with reusable components, cutting development time while improving performance. I also led the architecture and delivery of a global Drupal component library, standardizing UI/UX across 3 clients and accelerating new feature work.

I spearhead modernization across React, Astro, AEM, Drupal, and Node.js, translating complex business requirements into scalable technical roadmaps. I’ve engineered “high-performance Sling Servlets and custom WordPress plugins” for mission-critical enterprise integration, and orchestrated a large-scale migration of legacy Node.js services to LTS to eliminate security vulnerabilities and reduce runtime overhead.

Throughout my career, I’ve owned and managed delivery across multiple stacks while mentoring developers in React component development, TypeScript, Next.js, Node.js, Git, AWS architecture, AEM, and Drupal. Earlier work included directing AEM upgrades (6.1 to 6.5) with zero downtime and automating Drupal deployments via AWS CDK to increase deployment frequency.
