Solution architecture and AI context engineering

I design the solution. Structure the AI. Validate the delivery.

I define architecture, organize context and coordinate AI agents to build software and applications. Business rules, review and testing guide the work.

Let’s talk

Technologies I work with

List of technologies

  • HTML

    Front-end

    The structure of everything. Correct semantics is what makes a page readable by people and by machines.

  • CSS

    Front-end

    Layout, typography and motion. This is where an interface stops looking like a draft.

  • JavaScript

    Front-end

    The foundation of almost everything I deliver, from the browser to the server.

  • React

    Front-end

    Interfaces made of components: changing one screen does not break the others.

  • Next.js

    Front-end · Back-end

    Front-end and back-end in the same project, with server rendering where it actually matters.

  • Hono

    Back-end

    Lean, fast APIs, built to run at the edge.

  • React Native

    Mobile and desktop

    One app for iPhone and Android from a single codebase, published on both stores.

  • Electron

    Mobile and desktop

    Desktop apps for Windows, macOS and Linux built with the web stack.

  • Tauri

    Mobile and desktop

    Native desktop in a few megabytes, with automatic updates built in.

  • C++

    Mobile and desktop

    For what has to be genuinely fast and talk straight to the system.

  • Docker

    Infrastructure, data and cloud

    The environment running on my machine is the same one running on the server.

  • GitHub

    Infrastructure, data and cloud

    A record of everything shipped, with a deploy triggered by every approved change.

  • PostgreSQL

    Infrastructure, data and cloud

    A relational database for when the numbers have to add up at the end of the month.

  • Supabase

    Infrastructure, data and cloud

    Database, authentication and file storage ready on day one of the project.

  • Cloudflare

    Infrastructure, data and cloud

    The site served close to whoever opens it, with protection in front.

  • AWS

    Infrastructure, data and cloud

    Tailored infrastructure for when a project outgrows the standard setup.

  • Google Cloud

    Infrastructure, data and cloud

    Another possible home for the application, with Google data tooling close at hand.

  • Nuvemshop

    E-commerce

    An online store built and customized on the platform most used in Brazil.

  • Shopify

    E-commerce

    A store ready to sell abroad, with theme and checkout tuned for it.

Intelligence in how the work is directed.

I’m Willians Gonzaga, based in Jundiaí, Brazil. My work combines solution architecture, context engineering and AI-assisted software development. I translate business needs into scope, workflows and decisions that guide implementation.

I structure project memory, instructions, retrieval indexes and agent responsibilities in Claude Code and Codex. This context supports complex work with continuity and clear validation criteria.

In CloudPOS, this work takes shape in web, desktop and mobile applications, offline operation and payment integrations. Its AI features combine RAG and tool calling with rules where the model proposes and the application validates.

Real products. From idea to operation.
