Backend Developer Code level: Junior Confidence: Low Generalist

Junior Ruby developer focused on small TDD-driven utilities with a clear strength in writing unit tests for numeric logic. The strongest proven skill is test-driven development for numeric operations as shown by the detailed Calculadora RSpec suite (Calculadora/specs/calculadora_spec.rb). There is little to no evidence of backend production concerns such as APIs, databases, queuing, deployment, or observability in the public code.

Scalability & Performance

Not evidenced in public code

System Architecture

1/10

Overall system structure

Minimal module/class decomposition for a small utility; the code shows a simple class-oriented design without service boundaries or configuration concerns.

Evidence

Calculadora/specs/calculadora_spec.rb: uses a Calculadora class and exercises its methods through unit tests

Security & Auth

2/10

Protecting data and access

Basic input validation and edge-case checks are exercised in tests, showing awareness of invalid inputs and division-by-zero handling; no auth, token lifecycle, or secrets management is present.

Evidence

Calculadora/specs/calculadora_spec.rb: expects error string 'Soma deve conter somente números!' for non-numeric input

Calculadora/specs/calculadora_spec.rb: expects error string 'Dividendo deve ser diferente de zero!' when dividing by zero

Reliability & Observability

2/10

Stability and monitoring

Unit tests cover edge cases (type errors, division by zero, negative inputs) which supports basic reliability; there are no retries, timeouts, structured logging, or observability artifacts.

Evidence

Calculadora/specs/calculadora_spec.rb: tests validate behavior for decimals, negative numbers, and invalid types

Calculadora/specs/calculadora_spec.rb: tests check numeric formatting expectations such as raiz(4.5) == 2.12

Recommendations

Develop and maintain small Ruby libraries or CLI utilities where unit-tested numeric correctness matters.
Implement additional TDD-backed features and edge-case handling for command line tools or internal service utilities.
Contribute to entry-level backend tasks that emphasize clear unit tests and input validation while gaining exposure to databases, APIs, and observability.

Repositories

RealityStone_Viccenzo_Escarrone_Compass

Frontend Developer Code level: Junior Confidence: Medium UI Engineer

Front-end Web Developer at a junior level specializing in handcrafted HTML and CSS visual design for static and portfolio sites. The strongest proven skill is CSS visual design and interaction polish, demonstrated by style.css animations, gradients and card hover/transition patterns. There is little to no evidence of production-grade concerns such as robust state management, automated tests, CI, accessibility tooling or complex application architecture.

UI Component Architecture

2/10

How interface parts are built

Minimal component architecture - mostly static HTML/CSS and a default Create React App structure with no reusable component boundaries, composition patterns or custom hooks.

Evidence

ViccenzoE/Treinamento-Portfolio/index.html ViccenzoE/-Desafio-final---Trilha-Dev/src/App.js

Responsive & Cross-browser

3/10

Works on all screens and browsers

Basic responsive and cross-browser considerations - viewport meta, CSS grid layout and fluid units are present and prefers-reduced-motion is used, but no advanced responsive techniques or i18n/RTL readiness.

Evidence

ViccenzoE/Treinamento-Portfolio/index.html ViccenzoE/Treinamento-Portfolio/style.css ViccenzoE/-Desafio-final---Trilha-Dev/src/App.css

Performance Optimization

2/10

Speed of the interface

Some awareness of performance measurement via web-vitals integration, but no concrete optimizations such as code-splitting, lazy loading, bundle analysis or virtualization.

Evidence

ViccenzoE/-Desafio-final---Trilha-Dev/src/reportWebVitals.js ViccenzoE/-Desafio-final---Trilha-Dev/src/index.js

Accessibility & Semantics

3/10

Usable for everyone

Basic semantic HTML and form labels and alt text are present, indicating elementary accessibility awareness, but there is no ARIA on custom widgets, focus management, or automated a11y tooling in evidence.

Evidence

ViccenzoE/Treinamento-Portfolio/index.html

State Management & Data Flow

1/10

Managing data in the app

Very light state management - a single DOM toggle in vanilla JS and a default React app with no server-state discipline, request cancellation, optimistic updates or state machines.

Evidence

ViccenzoE/Treinamento-Portfolio/script.js ViccenzoE/-Desafio-final---Trilha-Dev/src/App.js

UX & Visual Polish

4/10

Look and feel quality

Good visual polish for a learning portfolio with animations, hover transitions and gradient styles, but UX edge states like loading/error/empty and undo patterns are not implemented.

Evidence

Recommendations

Implement and style small marketing or brochure websites and single-page portfolios where polished static UI and animations are primary requirements.
Convert static sections into small reusable React components to build a component library and practice component boundaries and composition.
Add basic web performance and accessibility tooling - integrate Lighthouse/web-vitals reporting into a dev workflow and run axe or eslint-plugin-jsx-a11y checks.
Practice state flows in React by building a small CRUD SPA with form validation, optimistic UI patterns and simple request cancellation.

Treinamento-Portfolio Object-Oriented-Programming -Desafio-final---Trilha-Dev

QA Engineer Code level: Junior Confidence: Medium Automation Engineer

Automation-focused QA practitioner (Junior) specializing in BDD-style UI automation and TDD unit testing. The strongest proven skill is writing BDD feature scenarios and unit tests, evidenced by the Gherkin feature files under Sprint5_Viccenzo_Escarrone (e.g. AutomationPrism/features/specs/login.feature) and the Calculadora RSpec spec (Calculadora/specs/calculadora_spec.rb). There is little or no evidence of CI/test orchestration, API/contract testing, performance/load testing or mature test infrastructure in the public artifacts.

Test Automation Frameworks

3/10

Building automated tests

Basic BDD UI automation using Cucumber, Capybara and simple page-object patterns; lacks robust fixtures, parallelization or advanced selector discipline.

Evidence

ViccenzoE/Sprint5_Viccenzo_Escarrone/AutomationPrism/features/support/env.rb ViccenzoE/Sprint5_Viccenzo_Escarrone/AutomationPractice/features/pages/base_page.rb ViccenzoE/Sprint5_Viccenzo_Escarrone/AutomationPrism/features/specs/login.feature

Test Coverage & Strategy

3/10

What and how to test

Reasonable unit and acceptance tests with negative and boundary checks, but overall exercise/tutorial-level coverage and no visible risk-based strategy or mutation/property tests.

Recommendations

Develop and integrate a CI workflow that runs the Cucumber and RSpec suites and captures artifacts (screenshots/logs) for failures.
Improve test infrastructure by adding isolated fixtures, data factories and explicit cleanup to make scenarios idempotent.
Expand automated test strategy toward API/contract tests and schema validation for backend resilience, not only UI flows.
Replace brittle sleeps and inline selectors with a clearer selector discipline and encapsulated page objects, and add conditional waits and per-test retry reasoning.
