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.

Selected work

Four systems, four decisions

alep — 01100% Atricon · Diamond Seal

01Public sector · Redesign + Front-end

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 front-end 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 — 03Decisions grounded in real research

03Product Design · Research · EdTech

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

Anamã Ateliê

From the name to the site: a whole brand, from scratch.

Context: Anamã Ateliê is a family business of handcrafted goods — laser-cut and engraved items tied to music and education. Here I didn't step into an existing system: I created the brand from the ground up.
Challenge: Give a craft business a coherent identity and a digital space worthy of the products — without losing the handmade character.
Decisions: I created the logo and visual identity system, and built the product showcase site. Tone, color, type and front-end designed as one thing.
Result: A complete brand and a live site, translating the family's handmade work into a digital presence.▸ Complete brand · Live site

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.
