Which technologies do you use for the frontend?

Mainly React, Astro and Vue, always with TypeScript. I pick the tool based on the project's needs: Astro for content- and performance-oriented sites, React or Vue for more interactive applications.

Do you start from a design or can you design it too?

I can work from your designs (Figma, Sketch, etc.) or help you define the interface from scratch if you don't have one yet. In both cases I take care of visual consistency and user experience.

How long does a frontend project take?

It depends on the scope. An optimized landing page can be ready in 1-2 weeks; an application with several views and integrations usually takes several weeks. After reviewing your case I give you a realistic estimate.

Will the site be fast and score well on Core Web Vitals?

Yes. Performance is a priority: I optimize images, loading and rendering to score high on Core Web Vitals and Lighthouse, because it directly impacts user experience and SEO.

Do you handle accessibility?

Yes. I work with semantic HTML and follow WCAG guidelines so the site is usable by as many people as possible and meets accessibility best practices.

Do you optimize the site for SEO?

I handle technical SEO: semantic structure, metadata, structured data, performance and indexing best practices. The content and keyword strategy can be coordinated with your marketing team.

Can you integrate the frontend with my backend or CMS?

Yes. I integrate the frontend with REST APIs, headless CMS and third-party services. If you also need a backend, we can coordinate it within the same project.

Do you offer maintenance after delivery?

Yes. The code is delivered documented and maintainable, and we can agree on a support and continuous-improvement plan so the project keeps evolving without friction.

Websites and apps that load fast and convert

Frontend web development

7+ years building interfaces for startups and companies. Designs implemented to the detail, measured performance and code your team can actually touch.

I want my frontend built

Frontend that looks good and performs better

A beautiful site that takes four seconds to load loses customers before it shows anything. I work all three at once: the interface your customer sees, the performance that decides whether they stay, and the code your team will be touching two years from now.

Interface and user experience

Responsive, mobile-first design
Accessibility (WCAG) from the start, not as a patch
Design systems and reusable components
Implementation faithful to the design, down to the pixel

Performance and Core Web Vitals

Image, font and loading optimization
Core Web Vitals measured before and after
Lighthouse audits with the fixes prioritized
Rescue work on slow sites already in production

Technology, technical SEO and maintenance

React, Astro and Vue, always with TypeScript
Integration with REST APIs and headless CMS
Semantic HTML, metadata and structured data
Documented code and an ongoing support plan

Why build your frontend with me?

No recycled template, no pretty but slow site, no untouchable code

I approach every project with a focus on performance, accessibility and maintainability, starting from your designs or helping you define them from scratch. The result is fast interfaces that score high on Core Web Vitals, improve conversion and that your team can keep evolving without friction.

Actually loads fast
Performance is measured before starting and before delivery. No optimizing by eye and crossing fingers with Lighthouse on the last day.
Your design, implemented to the detail
What you approved in Figma is what ships, on mobile and on desktop. No "that cannot be done on the web" halfway through.
Accessible without asking
Semantic HTML, contrast, focus and keyboard support from the first component. Building it this way costs far less than fixing it later.
Google understands it
Semantic structure, metadata and structured data sorted. Technical SEO is included, not a separate phase invoiced afterwards.
Code your team can touch
Reusable components, TypeScript and documentation. If someone new joins tomorrow, they do not start by rewriting everything.
No recycled templates
No bought theme with half a megabyte of plugins you never use. What gets built is what your project needs, and nothing else.

What I build in frontend

These are the projects I get asked for most. If your case looks like one of them, I have built it before.

Landing page that converts

One page for a campaign or a launch, loading in under a second and measuring what the visitor actually does.

Corporate site or marketplace

Several sections, search, filters and content that updates itself, wired to the CMS or API you already have.

Migration to a modern framework

Getting the project off WordPress or an abandoned framework and onto React, Astro or Vue without losing rankings.

Internal dashboard or app

Tools your team uses every day, with tables, long forms and states that hold up under real use.

Performance rescue

A site already online that scores badly on Core Web Vitals, with a report of what is slowing it down and the fixes applied.

Building an existing design

You have the Figma signed off and need someone to turn it into faithful, fast and accessible code.

How I go from your design to a site in production

I understand the project and the starting point

If there is a design, I review it and flag what will cause trouble on mobile. If there is none, we define it before writing code.

I build the component base

Typography, colors, spacing and reusable pieces. What is built well once repeats itself for free across the rest of the project.

I develop while measuring

Performance and accessibility are checked as it is built, not in a final audit when there is no time left to fix anything.

I deliver and stay around

Deployment, documentation of how it is put together and the handover to your team, with support afterwards if you want it.

Testimonials

What the companies I have worked with say

Real projects, real teams. Here are some of the people who trusted me with their frontend.

★★★★★

"I managed the project and with Miguelo it was easy. He delivered the landings pixel perfect and on time, blazing fast and friction-free. A 100 on PageSpeed and sales that felt it."

Alberto Fuentes

Freelance Project Manager · Kaspersky

★★★★★

"I wanted a beautiful site I could manage myself, and Miguelo nailed it. Years later it's still blazing fast, and after the rebrand I barely pay to maintain it."

David Lop

CEO and Professional Actor · The Attic Talents

★★★★★

"I had the idea clear and Miguelo turned it into a product. We iterated the features together and shipped a solid MVP, with both panels and the CRM working. It felt like having a technical partner, not just a developer."
