Custom software development.
I turn your ideas into high-quality apps, websites and systems.
Senior software developer specialized in scalable digital products for companies, startups and founders. React Native, React, Next.js, Angular, TypeScript and integrations — with a focus on timeline, clarity and software people can actually use.
Software engineering services.
- Mobile app development — Apps for companies that need to leave the idea stage, unblock a product or put an operation in the customer's pocket. The focus is a usable, stable product that can evolve.
- React Native developer — React Native is the stack I use most to ship mobile products. I use it to take an app from zero, stabilize a product in production or support a team without adding permanent headcount.
- Professional websites — Websites for teams that need to explain an offer clearly, show up better in search and turn a visit into a conversation. The visual design follows the content.
- Web system development — Systems that replace spreadsheets, email and manual process when the operation has outgrown a brochure website. The criterion is the routine of the people using it, not a generic dashboard.
- SaaS development — SaaS products for teams that need to turn a repeatable service into software: account, permission, billing and a routine the customer comes back to.
- Consulting and system modernization — For teams that already have software and need clarity: what to fix, what to keep and what is not worth rewriting now.
Real systems, with commercial context.
- Jobtto — A platform that connects demand and professionals, with the same product logic on the app and the website.
- Mais Negócio Vibra — A mobile product used in Vibra Energia operations, under continuous evolution by an allocated team.
- Colombo Bank — A banking app for tracking cards, limits and statements in everyday use.
- Gazin Bank — A financial app with operations that depend on APIs and clear feedback for the user.
- Parceiro da Construção — An educational app for construction professionals, with content and learning journeys.
- Bateponto Pontotel — A time-tracking app used every day, where check-in has to work even with a poor connection.
- Topotronics — An independent app for road engineering calculations, with accounts, store release and subscriptions.
- Sistema SIGA — A system used in operations, with both an app and a web presence.
- Ótica House — Web e-commerce focused on catalog, funnel clarity and the VTEX platform.
Before we request a quote.
What kind of project do you take on?
iOS and Android apps, professional websites, web systems, SaaS and consulting to modernize what already exists. React Native is the deepest specialty; web and integrations come in when the product needs them.
Do I need to understand React Native to hire you?
No. Companies hire an outcome: an app, a website, a system or a recurring product. The stack is a tool. In the quote conversation we talk about the problem, the timeline and the slice.
How does quoting work?
You describe the goal, the project type and the timeline. I reply with focused questions and a proposed slice. There is no public price table because effort changes with what already exists.
Do you work per project or per period?
Both. Fixed scope for defined deliveries; hourly or monthly for evolution and team support.
Do you only work in Porto Alegre?
I am based in Porto Alegre, Rio Grande do Sul, and work remotely across Brazil. In-person meetings only when the project needs them and they are feasible.
