ABOUT ME

Hi, I’m Guilherme.
I build things that work.

I’m a cloud solutions engineer with more than 13 years across technology operations, infrastructure, and software delivery. My background spans media and streaming, technology services, and financial technology.

My experience includes internal applications and AI tools in financial technology, with work on access controls and data protection. I bring that attention to security into the solutions I build.

Through Guil Silva, I help small businesses turn everyday challenges into practical tools. You work directly with me, from understanding the problem to building and handing over the solution.

SELECTED PERSONAL PROJECTS

My ideas.
Built into software.

Independent projects exploring software security, service-business websites, and billing workflows. Each one approaches a different practical problem.

SECURITY / DEVELOPER TOOLS

VibeSentry

A personal software-security project that connects GitHub pull requests with dependency scanning and structured findings.

TypeScriptGitHub / ProbotPostgreSQL
Explore the project

The problem: Developers need a practical way to surface potential security issues while changes are being reviewed.

The implementation: A GitHub integration handles pull-request events, runs dependency analysis, stores scan records, and reports findings through the review workflow.

The engineering focus: Connecting repository events, background work, organization-level data separation, and useful feedback for developers.

Project type: Independently developed software. No live scanner is connected to this portfolio.

LOCAL BUSINESS / WEBSITE PROTOTYPE

Prime JM Transfer

A transport-service website prototype for travelers visiting Florida, with a trip-request interface and WhatsApp contact.

Next.jsReactTailwind CSS
Explore the project

The problem: A local service business needs a clear way to explain its services and start a conversation with potential customers.

The implementation: Service sections and a form for pickup, destination, date, time, and an optional additional stop, alongside a WhatsApp contact action.

The engineering focus: A customer-facing interface that organizes trip details and makes the business easy to contact.

Project type: Website prototype. The quote form is not yet connected to a booking or submission service.

BUSINESS SOFTWARE / BILLING

CycloPay

A personal billing-management project for organizing customers, service agreements, payment workflows, and reporting.

ReactNode.js / ExpressPostgreSQL
Explore the project

The problem: Service businesses need to keep customers, agreements, and payment-related work organized in one application.

The implementation: A React frontend and an Express API with modules for authentication, organizations, customers, agreements, payments, webhooks, and reports.

The engineering focus: Bringing related business workflows together with a structured application and data model.

Project type: Independently developed software. Payment processing is not available through this portfolio.

These are personal projects, separate from my employment. Illustrations explain the workflows and are not application screenshots. Interactive demonstrations on the examples page use fictional data.
