At SingleSoftware, I build SSR-driven loading screens and CMS-backed dynamic homepages for a platform with 100k+ active users, improving SEO and first-paint metrics.

I've improved front-end delivery through on-demand script loading, code splitting, and interaction fallbacks, contributing to a 32%+ performance-score increase and 22% more average time on site. I also maintain CI/CD pipelines with test gating and observability hooks for safer releases.

Previously at TeamSoft, I helped migrate legacy systems to REST API architecture, refactored critical flows for SSR, and improved LCP, INP, CLS, caching, and organic search performance. At Flix Media and Brais Games, I delivered responsive interfaces, API integrations, authentication, reusable component systems, and crypto-platform experiences.

I bring hands-on full-stack experience across React, Next.js, Node, Nest.js, SQL, and modern front-end tooling, alongside a collaborative approach to code review, testing, and reliable delivery.
