Software Engineer
Software engineering. Product thinking.
I build complete systems, connecting interfaces, architecture and applied AI to the problems people actually face.
From the first decision to a working product.

I’m João. I work where engineering, product and the people using what I build come together.
I’m a Software Engineer at Solomon Digital Business, studying Systems Analysis and Development at Senac Paraná. I work across the product lifecycle: understanding needs, defining business rules, designing architecture and helping products evolve.
From a task’s approval flow to an organization’s data boundaries, I care about the decisions that make software useful and maintainable. AI supports my research and development workflow; technical responsibility stays with me.
Technologies used in my projects and development practice.
Domain-based interfaces, shared components and typed contracts in Leve.
Business rules, authorization and events connecting the API to the Atria product.
Organization-level isolation, migrations and background processing in business applications.
Connecting assistants to Atria through MCP. Exploring RAG and knowledge retrieval, as described on my profile.
The stack follows the problem. Clarity and maintainability stay part of the decision.
Context comes first. Technical choices need to work for the product and the people who will maintain it.
Business rules grouped by domain and explicitly scoped data access. In Atria, organization isolation follows the query.
Atria / NestJS + PrismaAuthorization, validation and tests are part of the workflow. In Atria, dedicated tests cover organization isolation and action permissions.
Atria / Isolation + PermissionsAn assistant can prepare an action without automatically executing it. In Atria, MCP drafts require confirmation inside the product.
Atria / MCP + OAuthChoosing what a product needs now is engineering, too. In Leve, AI and billing remain disabled while the daily routine workflows evolve.
Leve / Next.js + NestJSProfessional practice, education and products evolving together.
