Alex Berry

I’m a Senior Software Engineer specializing in building scalable JavaScript applications, bringing product requirements to life across both frontend and backend systems. I focus on pragmatic engineering decisions, clean code practices, and modern architectures that stand up in production.

At Perlego, I’ve built and maintained full stack platforms using React, Next.js, Node.js, and Express, improving content delivery workflows as product needs evolved. I helped reduce page load time by 27% through optimized rendering strategies, and I strengthened reliability and uptime to 99% with fault-tolerant service patterns and efficient caching.

I also design and implement backend services and APIs that integrate across internal and external systems, including event-driven systems that support background jobs and asynchronous workflows. In production, I reduced data processing latency by 35%, improved API performance and database query response times by 25% under peak traffic, and enhanced observability (logging, monitoring, alerting) to cut incident resolution time by 30%.

Earlier, I delivered end-to-end features at AND Digital and helped modernize legacy platforms into modular, service-based systems. Across roles, I’ve used CI/CD pipelines to enable frequent releases, developed automated testing approaches to improve release stability (reducing production defects by 23%), and applied AI-assisted automation to improve content processing consistency and structured data generation—because I enjoy shipping real outcomes that make systems faster, clearer, and easier to use.
