Web performance engineer & JAMStack architect
I build blazing-fast, SEO-optimized web architectures using Next.js, Astro, and headless CMS platforms. I help businesses achieve perfect Core Web Vitals and seamless content delivery.
ABOUT ME
Architecting the modern web for speed and scale
With 8 years of experience in web development, I specialize in solving complex performance and infrastructure bottlenecks for high-traffic platforms. My career began in agency environments delivering custom CMS solutions, which taught me the critical importance of aligning technical architecture with business and marketing goals.
During my time in the fintech sector at IronFX, I modernized development workflows, built scalable full-stack architectures, and introduced containerized environments to ensure reliable, fast deployments.
Today, I focus on decoupling monolithic websites using modern headless architectures (Strapi, Decap CMS) and building blazing-fast frontends with Next.js and Astro. My core focus is bridging the gap between engineering and growth—delivering secure, heavily optimized platforms that achieve perfect Core Web Vitals scores, ensure strict accessibility, and rank flawlessly on search engines.

Technical strategies and business value
Why do you advocate for headless CMS and component-driven architecture?
Monolithic systems often force a compromise between content management ease and frontend performance. I use component-driven engineering to assemble interfaces block-by-block, decoupling the backend (Strapi, Decap CMS) from highly optimized frontends (Next.js, Astro). This gives marketing teams an intuitive publishing interface while guaranteeing zero-bloat delivery, tighter security, and scalable infrastructure without traditional database constraints.
How do you guarantee high-performance Core Web Vitals?
Performance isn't an afterthought; it is the foundation of the architecture. I refuse to use bloated legacy themes or heavy page builders. Instead, I prioritize shipping zero JavaScript to the client by default using Astro or leveraging Server-Side Rendering (SSR) and Static Site Generation (SSG) with Next.js. By optimizing LCP through edge caching, automated image pipelines, and critical CSS extraction, I ensure pages load instantly, which lowers ad CPC and maximizes campaign ROI.
How do you bridge the gap between engineering and marketing teams?
In competitive markets, engineering must empower growth teams rather than block them. I build infrastructure that allows non-technical staff to launch campaigns safely and autonomously without risking the site's layout or speed. This includes setting up secure editing dashboards and configuring third-party analytics without blocking the main browser thread.
