About me

An unusual but powerful mix of data, audio and creativity.

I’m Guillermo Fernández Vega, a Data Science Engineering student, web developer and professional audio technician. My approach combines technology with creative sensitivity: analyzing information, building digital solutions and communicating ideas with a distinctive identity.

I’m interested in projects where data is more than numbers: a way to better understand a business, an audience, a community or a musical work.

I’m also part of Piroclastos. There I’ve learned how to create from scratch: composing, recording, producing, communicating an aesthetic and sustaining an artistic project with its own identity.

Web Development

I design fast, easy-to-navigate websites that clearly explain who you are, what you do and how to contact you.

Landing pages and portfolios Responsive design Basic SEO and optimization WhatsApp and social media integration

Audio and Music

I work on audio, mixing and production with a musical perspective, taking care of both the technical side and the emotion of each project.

General timeline:

  • • Proposal: same week
  • • Development: ~1 week (depends on complexity)
  • • Revisions: 3 rounds (variable time)
  • • Launch: Once revisions are finished

The exact timeline depends on the project scope and your availability for feedback. We discuss this in the proposal.

Yes, during development:

I include 3 rounds of revisions in the price. In each round, you send a list of changes and I implement them.

After launch:

Additional changes cost $20,000/month maintenance, which includes updates, adjustments and support.

It's important to be aligned during the 3 revision rounds to avoid extra work.

Bank transfer (Chile).

You can deposit into the account I share once you accept the proposal. I wait for deposit confirmation to begin.

By default, I manage the hosting and domain.

The costs are quoted separately from development. What matters: you have full access to your domain and hosting, and can switch provider whenever you want.

If you prefer: I can guide you to manage your own hosting. I teach you how to use it and connect your domain.

Yes, 1 month of initial support.

After launch, you get technical support for 1 month: questions, bugs, small adjustments.

After that month: If you need changes or maintenance, the $20,000/month plan applies.

I have known Guille since childhood, and he has always been a creative person. Now, professionally, he helped my colleagues and me design the website for our architecture office, Periferia. He listens, is willing to meet our requirements and gave us more than we knew to ask for. We loved how he translated our vision into his work. I recommend him without hesitation. Thank you, Guille!

Accessibility and neurodiversity

Designing for different ways of thinking

Cognitive accessibility should not be an optional extra. I care about digital, creative and working experiences built with greater clarity, flexibility and respect for different ways of processing information, learning and communicating.

This space brings together inclusive design principles, mental health without stigma and a critical view of how we understand productivity and creativity.

Read my personal perspective Let’s talk
The full page develops these principles from a personal perspective.

Cognitive accessibility

Clear hierarchy, understandable language, predictable navigation and less unnecessary friction.

Flexibility and autonomy

Processes that do not force everyone to organize, focus or communicate in exactly the same way.

Mental health without stigma

Speaking respectfully, without reducing anyone to a label or assuming there is only one valid experience.
