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.

Did you measure the mobile result on a first visit before anything was cached? I'd be interested to see how much of that speed comes from the query changes.
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.

firendev: brand identity and website.
firendev is a video studio, and the name carries the whole brand. Fire, for the spark that starts every piece. Firenze, for a craft measured with proportion and geometry. Develop, in its two senses: developing film and developing software. One line holds it together: developed like software, finished like film.
Everything else grows from that. The spark is the dot of the i. The floor is the herringbone brick of Florence's Duomo. The mark is a camera frame waiting for its spark.
I'd love your honest take on the mark and the hero.

It's a great design 🔥
I liked the animation in Hero; I'm curious which library you used.

Top-notch design.
That works. If the screen recording clearly demonstrates the product, your written explanation can carry the “what I built and why” story.
Here’s a polished version you can use for your Contra challenge submission:
What I built & why
I built PawRoute, a smart booking and automation experience for a fictional solo mobile dog groomer, Maya, based in Austin, Texas.
I chose mobile dog grooming because booking isn't as simple as finding an empty calendar slot. Every new inquiry can require the owner to check the customer's location, understand the dog’s needs, recommend a service, calculate pricing, find a time that works with the driving route, confirm the appointment, send reminders, and handle cancellations.
I wanted to answer one question:
How can I turn “Can I book?” into “You’re booked” with as little work from the business owner as possible?
So I designed PawRoute around a simple 3-step customer booking experience. Customers provide their location and dog details, receive a recommended service with clear pricing, and choose from available appointment times.
I also created Best Route Match, which prioritizes appointments when Maya is already working nearby instead of treating every available time equally.
Behind the customer experience, PawRoute handles the repetitive work: booking confirmations, reminders, customer information, route updates, rescheduling, and automation activity.
I also designed an owner dashboard where Maya can see appointments, customers, her driving schedule, and what PawRoute has automated.
Finally, I added a cancellation-recovery workflow. When an appointment opens up, PawRoute can help identify suitable waitlisted customers and refill the slot instead of requiring Maya to manually message people.
The goal wasn't simply to build another booking website. It was to design a system where the customer sees simplicity while the complexity is handled behind the scenes.
3 steps for customers. Less scheduling work for Maya.
