Frontend Architecture for products that cannot afford to fail.
I turn complex problems into scalable, accessible digital products designed to evolve.
About
Hi, I’m Vagner.
For over 10 years, I have turned engineering challenges into digital products built to evolve. My experience spans enterprise and financial systems, frontend architecture with React and Angular, micro frontends, and accessibility.
I lead technical decisions, help teams deliver with clarity, and build independent products. I also explore how AI can amplify — not replace — the judgment of people who create software.
How I build
Engineering Principles
Build for maintainability.
Readable code and explicit decisions keep products healthy over time.
Architecture should accelerate teams.
Clear boundaries reduce dependencies and increase delivery autonomy.
Accessibility is part of quality.
Inclusive experiences are a product responsibility from day one.
Measure before optimizing.
Evidence guides priorities and prevents complexity without returns.
AI should amplify engineers.
Intelligent tools should elevate human capability and critical thinking.
Where I create impact
Expertise
Architecting solutions that balance immediate business needs with long-term technical sustainability.
Micro Frontends
Independent delivery strategies that reduce coupling and speed up teams.
React & Angular
Responsive, sustainable products with choices guided by context.
Technical Leadership
Clear direction, mentorship, and decisions that move teams forward.
AI-assisted Engineering
AI applied to engineering workflows to expand quality and velocity.
Accessibility
Inclusive systems from architecture to the smallest interface detail.
Independent work
Products & Initiatives
Independent products combining architecture, experience, and purpose.
Available on the App Store
Petal
A habit-tracking platform designed to provide a lightweight, private, and offline experience, with no ads or reliance on cloud services, putting users in control of their own data.
In development
EquiProvas
EquiProvas centralizes equestrian competition management, bringing registrations, events, horses, competitors, and results into one modern platform. Its first discipline at launch will be barrel racing.
The next challenge
Turning ideas into products that make sense.
If you’re building a product, leading a team, or solving a technical challenge, let’s talk.
