The same quality ~100 businesses already rely on daily.

For over 2 years I've been building ProABA — a healthcare platform used by ~100 clinics across Brazil. This real-world experience is what guarantees quality and reliability in your project.

Production

real system, used every day

ProABA taught me to think like a product person: it's not about technology, it's about solving the client's problem. That mindset is what I bring to every site I deliver.

Real production experience

I'm Marcos — a software engineer from Rio de Janeiro. For over 2 years I've been building ProABA, a healthcare platform used by ~100 clinics in Brazil. I use AI daily to deliver faster and with higher quality.

Why I work directly with clients

I started working with entrepreneurs because I saw a gap: agencies are slow and expensive, generic freelancers don't deliver quality, and platforms like Wix don't scale. My offering is agency results at freelancer prices.

Cutting-edge tools, fast delivery

I use the same tools as the world's top startups. You don't need to know their names — what matters is your site is fast, beautiful, and professional. In days, not weeks.

Questions

Frequently asked questions

Everything you need to know before getting started.

How much does it cost?
Essential Site is R$397, Professional Site is R$797 and Digital Presence is R$1,497. Fixed price, no surprises. The most popular is the Professional Site, which includes multiple pages, a blog, full SEO and Instagram creatives.
How long does it take?
Essential Site in 7 days, Professional Site in 10. I always confirm the timeline upfront and send updates along the way.
Are there monthly fees?
The project itself is a fixed price — no mandatory monthly fee. After delivery, there are optional maintenance plans (R$47/month) and Instagram creatives (R$97/month) — but only if it makes sense for you.
I already have Instagram, do I really need a website?
Instagram is a storefront you don't own. It can go down, change its algorithm, and you don't show up on Google. Your own website is the only online space that's 100% yours and professional.
Can't I just use Wix or Canva?
You can, but you'll hit limitations quickly — generic templates, poor speed, no real customization. A custom-built site delivers exactly what your business needs.
Is hosting really free?
Yes. I use platforms like Vercel and Cloudflare that offer fast, free hosting. You pay nothing per month.
How does the referral program work?
You refer someone who needs a website. When they close a deal, you both win: R$50 via Pix for you and R$50 discount for the referred person. No limit on referrals.
Is it my site? Can I take it to another developer?
Yes. The code is 100% yours. No lock-in contract, no dependency. If you want to hand it off to another dev, that's your right.
