Independent Tech Lead—Developer

BUFF Stories

#front-end

Founded in 1992, Buff is renowned worldwide for its neckwear, made from recycled bottles and produced with clean energy. Its seamless stretch, exceptional comfort, and versatility have made it a favorite among runners, cyclists, hikers, climbers, and more. For their new website, I implemented their blog, focusing on improved performance and engaging animations.

Carolina Herrera has built a reputation for elegance over the past 40 years. At B-Reel, we were entrusted with bringing the brand into a digital experience. From research to execution, we reimagined the brand’s entire online presence, including UX/UI design and content, to create an experience that stands out. As Tech Lead, I contributed by implementing key features such as the makeup customizer, virtual try-on, and more.

Over a decade of experience implementing fully custom, high-quality interactive experiences.

Services

Joining your team as a freelancer or handling the project independently.

Front-end

From large-scale websites to creative campaign landing pages, we bring designs to life with precision. While our roots are in technology, design is just as important to us. We carefully implement designs from the ground up, with a strong focus on motion, interaction, and user experience. Our goal is to create high-performance solutions that not only work seamlessly but are also visually compelling.

Every detail receives meticulous attention to ensure a polished final result.

Back-end

We offer fully customizable experiences, always with a headless approach, selecting the best platform for each project. Everything properly documented, so you and your team can work independently, saving both time and costs.

We work with Strapi, Contentful, Contentstack, Prismic, Storyblok, WordPress, and Shopify.

Please note, we do not offer back-end as a standalone service.

WebGL

An innovative web experience can significantly enhance your brand’s perceived value and boost conversions. We support you every step of the way, from initial concept and prototyping to implementation, ensuring your project stands out with cutting-edge technology and design.

AI & Web3

We’re actively working with AI and Web3 in current projects, constantly exploring their potential. From developing an NFT marketplace in Inkollectors to creating a virtual assistant that enhances user experience through AI, we’re excited about what these innovations can achieve and always open to exploring new possibilities with each project.

Headless E-Commerce

A faster site, better scalability, and more conversions. If the standard templates from platforms like Shopify or WooCommerce don’t deliver the experience your business needs, we’re here to help. We focus on improving loading times, enhancing usability, and, most importantly, creating a fully personalized experience for your customers.

We work with Shopify, Square, WooCommerce, and more.

Web & Native Apps

We develop native apps using React Native, a framework powering thousands of apps, including familiar ones like Facebook, Skype, Outlook, and Discord. Additionally, any website can become a web app with its own icon on the home screen, thanks to Progressive Web Applications (PWA).

Whether you’re looking for a PWA or a fully native app, we provide tailored solutions.

Site Maintainance

We aim to build long-term relationships with our clients. We don’t just launch and forget. We offer annual packages to help you manage your site after it’s live, covering everything from updates and optimizations to security checks and protection against attacks, as well as adding new features.

We’ve got you covered.

In-house Support

I collaborate individually, as the sole freelance partner, with studios and agencies on a project basis, building open partnerships to achieve shared goals. My approach is always flexible, adapting to your team’s schedule. I place a lot of importance on effective collaboration and keeping a positive, friendly attitude throughout the process.

This is especially efficient if you’re working with technologies like Nuxt/Vue, Next/React, Vanilla JS, and WebGL.

About

Over a decade of experience implementing fully custom, high-quality interactive experiences for brands and companies worldwide.

Christian MacMillan

Born in Mallorca, I always had a strong interest in design and tech. While studying computer engineering, I quickly found myself leaning towards more creative ways of implementing software. Inspired by motion and interactions, and motivated to deepen my expertise in these areas, I eventually moved to Madrid and later to Barcelona, where I had the opportunity to work at agencies like Vasava and B-Reel, collaborating with companies and brands such as Google, Nike, and Netflix.

In 2020, I began my solo journey as a freelancer. Over the past few years, however, I’ve rented a workspace and frequently collaborated with other professionals to meet my clients’ needs, which is why it has gradually evolved into what now feels more like a small studio. From fellow developers to designers, copywriters, and SEO experts, I’ve built a network that ensures our final results meet the high standards I aim to deliver.

That said, my priority is to put personal interaction first, making it easy and enjoyable to work together. As you scroll down, you’ll find some of our clients, their experience collaborating with us, a photo gallery to get to know the studio a little better, and a showcase of some recognitions we’ve received over the years.
