Technical performance engineering and Core Web Vitals optimization for comoimportarmicoche.es.
Achieved 92+ performance scores on mobile alongside 100/100 ratings in SEO, Best Practices, and Accessibility on a live production WordPress site by streamlining front-end asset delivery and eliminating backend execution bottlenecks.
Key Engineering Highlights:
• Asset Optimization: Minified, combined, and deferred non-critical CSS/JS, significantly reducing render-blocking resources and critical path latency.
• Next-Gen Media Pipeline: Implemented WebP image conversion, explicit aspect ratio dimensions to eliminate Cumulative Layout Shift (CLS), and native lazy-loading.
• Clean Architecture: Optimized dynamic database queries and custom PHP scripts to maintain near-instant Server Response Time (TTFB) without relying on heavy caching plugins.
• Core Web Vitals Targets: Focused on Largest Contentful Paint (LCP) and Interaction to Next Paint (INP) to deliver sub-1.5s real-world loading times on mobile devices.

Yeah, this was a cold run in PSI. The DB cleanup was actually huge for TTFB—dropped uncached server response under 200ms, mostly by clearing bloated wp_options and fixing custom loops. Caching handles repeat hits, but the backend fix was the main win.
Hi Contra! I'm Shailesh, a full-stack & AI engineer with 5+ years of production experience, now taking on freelance projects full-time.
What I build:
• AI assistants that answer from your own documents (RAG), with hand-off to a person when the answer isn't there
• Multi-agent LLM workflows with OpenAI and Claude
• Web apps and MVPs with Laravel, Python, React/Next.js and React Native
• WordPress/WooCommerce fixes and speed-ups
Recent work: a multi-agent AI lesson planner for an education non-profit, an offline-first React Native app for teachers, and a zero-downtime integration between two national platforms.
Building something with AI, or need a dependable full-stack engineer? Send me a message or check out my services.
welcome to Contra! RAG with a hand-off to a real person is such a practical setup
I published my first Framer template. It’s free.
Raw Roast is a site for a coffee shop that roasts its own beans. The style is street-like: big hand-drawn lettering and black-and-white doodles.
What’s in it:
Home, About, Our Process, Gallery, CMS-based menu, Item page, Cart, 404, 401 and legal pages, Desktop, tablet and phone layout.

Feel free to use it and change it for your own shop. If you do, I’d be glad to see the result.😍
Crisp, clean, and effective.
