PHP · Yii2 · Laravel
Business systems, APIs, reusable components and legacy updates. Earlier work at SourceOne also includes Laravel.
Architecture, code
and operations.
My technical skills connected to my work: languages, apps, data, cloud and delivery. Explore the skills and the projects that use them.
Languages and backend
From application rules to services and integrations.
Go
APIs, concurrent services, WebSocket and clear domain, application and infrastructure boundaries.
Python · FastAPI
APIs, data connectors, automation and local tools. My role in Onerom is as a contributor.
C# · .NET
APIs and business systems. InspectApp includes a dedicated report generation component. My contribution varies by project.
JavaScript · TypeScript
Web interfaces, integration contracts and apps with clear component responsibilities.
Dart
Flutter apps, testable rules and device features.
Swift · Kotlin
Native integrations in FretUp and ToOn: Android/iOS features, audio and widgets in FretUp; CallKit/PushKit and native calls in ToOn.
Java · previous experience
Earlier Java development at CI&T. This is work history, with no claim of a current Java portfolio project.
C# · Unity · mobile games
Physics, gameplay, presentation and offline storage in Jeepão, with assembly boundaries.
Node.js · Express
Messaging integration documented in naGestão, with a Node.js/Express adapter separate from the PHP system.
Web, mobile and experience
Products built for their screens and real use.
React · Next.js
Feature-based interfaces, navigation, states and API integration.
Angular · Ionic · Capacitor
Field app and interfaces connected to Inspect operations.
Flutter · Android · iOS
Mobile apps with local storage, permissions, sync and platform checks based on each product.
HTML · CSS · accessibility
Responsive layouts, keyboard navigation, clear states and real use needs.
Vue · previous experience
Vue application updates at SourceOne, alongside Laravel, React and C# APIs.
WebSocket · real-time communication
Real-time communication in ToOn and event transport in the FootGrid backend, with separate data storage.
Databases and integration
Application databases, external sources and message transport have different roles.
MySQL
Storage and queries in PHP systems, AIceberg runtime, FootGrid and Inspect Lead. Also an external data source for AInalise.
SQL Server
Business systems, queries, integrations and latency and concurrency diagnosis.
PostgreSQL
Platform storage and persistence contracts, data modelling, queries and access isolation.
Oracle
Business data sources in AInalise, connector compatibility and permissions. Earlier work at TCEMG also includes Oracle.
Redis
Cache and operations in ToOn, Redis Streams transport in AIceberg and cache/queue infrastructure in Lobapp. Each case separates existing work from planned features.
SQLite · local data
Local database in Printora and mobile apps, with offline sync where used. ToOn uses SQLCipher for encrypted local storage.
SQL · modelling · performance
Data modelling, indexes, queries, SQL scripts and storage diagnosis. Backup and restore need their own checks.
Cloud and infrastructure
Infrastructure, connectivity and operations for each product.
AWS
Hosting and operation of AInalise in the AWS environment documented by the project.
Oracle Cloud Infrastructure · OCI
AIceberg operations and delivery through a self-hosted GitHub Actions runner on OCI.
Microsoft Azure
Azure SQL, Microsoft Fabric and Entra integration in AInalise; Azure AI connectors in AIceberg.
On-premises · agents · edge
Agents and diagnostics for local network data sources; local device operation in Printora.
Linux · VPS · dedicated servers
Linux, VPS and dedicated server operations: services, permissions, releases and diagnosis.
Docker · Compose · Nginx · systemd
Repeatable environments, web proxy, services and workers, with configuration separate from code.
Render
ToOn hosting with a Go API in Docker and PostgreSQL/Redis services defined in its Blueprint. Environment settings and health checks support operations.
Cloudflare
Private ToOn media stored in S3-compatible R2; Inspect Lead web access through Cloudflare Tunnel. These services have separate roles.
Firebase · notifications
Firebase and mobile notification integrations in Flutter apps. These links indicate app use, without claiming backend hosting or Firestore.
DevOps and delivery
From a Git change to operations, with clear checks and rollback.
Git · GitHub Actions · CI/CD
Validation and release workflows, self-hosted and hosted runners, branches and tags based on each repository’s rules.
Builds · releases · rollback
Builds tied to versions and commits, environment checks, smoke tests and rollback steps.
Secrets · access · environments
Private configuration outside public assets, restricted permissions and separate local, staging and production environments.
Logs · diagnostics · observability
Safe logs, request or job context and failure diagnosis. Release and real operation have separate checks.
Bash · operational automation
Checks, packaging and operation scripts with validation and clear failures.
Architecture, quality and AI
Decisions that connect requirements, code and evidence.
SOLID · responsibility boundaries
Decisions that separate UI, rules, data and infrastructure for each project stage. This includes planned architecture for products still being defined.
Tests · contracts · risk-based validation
Rule and integration tests, API contracts and checks of affected flows. Local checks do not replace production or device acceptance.
AI-assisted engineering · modelo_projetos
A reusable base of context, requirements, decisions, work packages and evidence for AI-assisted engineering.
