Sodoma
Hi, I'm Guilherme.
I've been a developer for over 7 years and I handle everything personally: from the first conversation to support after launch. No agency in between, no outsourcing.
I work with energy and education companies day to day and serve local businesses with the same standard: current technology, organized code and deadlines met.
I use AI every day — to write, test and review code — which is why I deliver in weeks what used to take months. Everything AI produces goes through me before it reaches you; what it doesn't do well, I do by hand.
If you want someone technical who also understands business, let's talk.

Questions every client asks.
Straight answers, no jargon.
How much does a website cost?
Landing pages from R$ 1,200, business websites from R$ 2,700, online stores from R$ 5,000 and custom systems from R$ 7,000. The exact price is agreed in writing before we start and doesn't change midway.
How long does it take?
Landing page in 3–7 business days; business website in 10–20; online store in 20–45; custom system in 30–60. The timeline is set together with the scope and I deliver 100% of projects within it.
Will I be able to update the site myself?
Yes. Every project comes with a simple panel where you change text, photos and products and publish news without a developer. I give a quick training on delivery.
What if I need changes later?
Monthly maintenance plans (from R$ 249) cover hosting, security and hours of tweaks. Outside a contract I charge R$ 220/h with a 2h minimum.
How does payment work?
50% on approval and 50% on delivery, via Pix, bank transfer or international payment. Card installments or other terms can be agreed before we start. Book a project + 12 months of maintenance and get 10% off.
