How I work

I work at the intersection of design and engineering. I shape the experience, model the database, write the front and the back — and I take ownership of the whole problem, not just my slice of it. Much of my career has been building systems that must be reliable and clear at once: public portals, document-management platforms, products with purpose.

Four systems, four decisions

Transparency Portal · ALEP

A public portal that met 100% of audit criteria.

Context
The Transparency Portal of the Legislative Assembly of Paraná (ALEP) is the public gateway to spending data, contracts and legislative activity. It is assessed by Atricon — the Brazilian association of audit-court members — against strict transparency, usability and accessibility criteria.
Challenge
Restructure and redesign a dense, dated, hard-to-navigate legacy portal — without losing any data and while meeting every compliance criterion. Real transparency isn't just publishing data: it's making it findable and understandable.
Decisions
I reorganized the information architecture around what citizens actually look for. I redesigned the interface and built the plataform with a focus on clarity, visual hierarchy and accessibility. I restructured navigation to shorten the path to every piece of information.
Result
The portal reached 100% of Atricon criteria, earning the Diamond Seal — the highest rating.▸ 100% Atricon · Diamond Seal

TradeSaaS / Iarandu · Trade Marketing

A document manager for one of Paraná's largest agencies.

Context
Built for the Trade Marketing operation of one of Paraná's largest advertising agencies, TradeSaaS centralizes the document lifecycle across multiple user roles.
Challenge
Support flows with distinct roles — supplier, operations, management — each with its own permissions, validation steps and views, while keeping the system simple to use despite the complexity underneath.
Decisions
I modeled the multi-role flows, document validation and approval, and features like batch (ZIP) download. I absorbed the complexity in the back-end so the interface stayed straightforward for daily users.
Result
A platform that organizes a previously scattered document process, with clear approval trails for each role.▸ Multi-role flows · Traceable approval

Educando · Worldfund

Designing for education means designing for collaboration.

Context
As Product Designer at Educando by Worldfund, I worked on education and teacher-student collaboration initiatives, including the STEM Brasil CAV platform — a collaboration tool for teachers.
Challenge
Understand the real needs of teachers and students and translate them into concrete improvements, while helping conceive a new student-facing platform.
Decisions
I ran user research, competitor analysis and opportunity mapping. I contributed to shaping the new experience, connecting discovery to product design.
Result
Product decisions grounded in evidence of real use rather than assumption — the foundation of a more useful educational tool. In the same vein, at April9 I spent five months on Loveable, a social network with online courses for people with disabilities: I built features, screens and reusable components, took part in database modeling, and collaborated on experience design to make it more inclusive.▸ Decisions grounded in real research

Link Sinistros

A site worthy of insurance's moment of truth.

Context
Link Sinistros is the outsourced claims team for insurance brokers — filing, follow-up and policyholder support across Brazil, based in Curitiba. The challenge here wasn't stepping into an existing system: it was giving a B2B service the digital presence that a claim — insurance's moment of truth — demands.
Challenge
Communicate a trust-driven B2B service clearly to brokers, balancing professionalism, closeness and conversion in a single institutional site — the point where a policyholder decides whether to renew or leave.
Decisions
I built the site in Next.js 15, with a Brazil SVG map showing the nationwide coverage, a 3D carousel for the Link product ecosystem, and an integrated accessibility widget. Content, hierarchy and front-end designed to carry the broker from first contact to proposal.
Result
A live site that translates Link's service into digital presence: national coverage made visible, the ecosystem laid out, and direct contact channels via WhatsApp, form and email.▸ Live site · Complete digital presence

    Entrepreneur

    Co-founder of a tech company and a family handcraft studio.

I started in design (UFPR, 2016) and walked the whole path: web designer, front-end, full-stack, now tech lead — earning a degree in Systems Analysis & Development along the way. That dual track — design and engineering — defines how I work: I think through the experience and build what sits underneath it.

I'm also an entrepreneur: co-founder of a tech company and of a family handcraft studio. I'm drawn to problems that mix clarity, systems and purpose.
