Sobre
Engenheiro Full Stack da Polônia
Arquitetura API-first
Cada sistema projetado em torno de limites REST bem definidos. O frontend consome APIs — nunca acoplado a internos do backend.
CMS reutilizável e núcleo de reservas
Headless CMS + mecanismo de reserva alimentando múltiplas propriedades. Mesmo núcleo, diferentes inquilinos.
Painéis administrativos seguros
RBAC, permissões com escopo, sessões httpOnly, proteção CSRF. Superfícies admin isoladas do vetor de ataque público.
Modelagem de dados PostgreSQL / Prisma
Integridade relacional primeiro. Prisma para consultas type-safe, migrações e evolução de esquema.
Deploys Docker / nginx / Linux
Stacks VPS de nível de produção. Docker Compose, proxy reverso nginx, SSL automatizado, fail2ban.
Fluxos de automação AI / LLM
Geração de documentos, automação de formulários, análise de repositórios. Pipelines orientados por prompt para resultados consistentes em escala.
Projetos
Sistemas que projetei e entreguei
Headless CMS Platform
Headless CMS + booking engine ecosystem. Multi-property scheduling, real-time availability, and content management delivered via REST API.
Booking & Payments Platform
Stripe and BLIK integration with invoice generation, availability calendar, and multi-currency support. End-to-end payment lifecycle.
Admin Panel / RBAC CMS
Role-based access control with granular permissions. Media management, content editing, pricing rules, and real-time analytics dashboard.
AI/LLM Automation Layer
Document generation, form automation, repository analysis, and prompt-driven workflows. Designed for consistent output at scale.
WordPress / Gravity Forms Automation
Custom plugins for event registration, exhibitor management, and conditional form logic with automated PDF delivery.
VPS Production Stack
Docker Compose orchestration with nginx reverse proxy, PostgreSQL persistence, automated SSL via Certbot, and hardening from first principles.

Segurança
Minha abordagem para sistemas seguros
Admin / Public Separation
Strict boundary between authenticated admin surface and public-facing endpoints. Admin routes isolated behind auth middleware.
RBAC & Permissions
Role-based access control with granular permissions per resource. No god-mode accounts — every action is scoped.
API Key Management
Keys stored as environment secrets, never committed. Rotation strategy in place. Third-party keys isolated per service.
Session & Auth
HttpOnly secure cookies, CSRF tokens, session invalidation on role change. No local storage tokens.
Input Validation
Zod schemas on every API boundary. No raw SQL. Parameterized queries via Prisma. Content Security Policy headers.
Service Isolation
Docker Compose networks isolate services. Admin panel not reachable from public network. Database no external ports.
Firewall & nginx
UFW + fail2ban for brute-force protection. nginx rate limiting, request size caps, and security headers.
Attack Surface Reduction
Minimal exposed ports. Unused services removed from production images. Health-check endpoints behind auth.
Monitoring Readiness
Structured logging, health-check endpoints, and alert-ready architecture. Ready for Prometheus/Grafana or Datadog integration.
