The person behind JB DEV
JB DEV is the studio of Jonathan Balieiro, a full stack web developer based in Indaiatuba, São Paulo, Brazil. You talk directly to the person who designs, codes and looks after your project after launch.

Who Jonathan is
Jonathan Vinicius Balieiro de Oliveira is a full stack web developer and the founder of JB DEV. He follows every project personally and brings together development, product thinking and visual care in every delivery.
JB DEV was created for companies and professionals who want a stronger online presence, better-organized processes or to bring an idea to life, without going through an agency with layers of account managers.
Hands-on experience
The portfolio brings together real, live projects in very different industries: a jewelry online store, a phone store website, a sales CRM, booking systems for a barbershop and a nail designer, a personal finance app, a beauty studio landing page and a digital menu.
Each one solved a different problem, and that range is what makes it possible to look at your business and suggest the simplest path, whether it is a website, custom software or an automation.
How we work
Every project goes through four stages, with you following closely:
- Discovery: understand the business, the customer and the problem before talking about screens
- Direction: a fixed proposal with scope, timeline and an approved layout
- Build: development with frequent deliveries so you can see progress
- Launch: publishing, training and support to keep evolving after launch
What sets us apart
- Proprietary code: code, domain and access are in your name at the end of the project
- Direct contact with the person who codes, no middlemen
- Tailor-made projects, sized for where your business is today
- In-person meetings in Indaiatuba and the region, remote work anywhere
- Transparent communication and replies within 24 hours
- Ongoing support and improvements after delivery
