I am a Software Engineering Consultant specializing in robust modular architectures, automated tooling, and high-scale backend infrastructure.
- Modular Backend Architecture: Designing highly cohesive, type-safe application structures with NestJS and Node.js.
- Fullstack Capability (React): Building performant, data-dense interfaces and dashboards that integrate seamlessly with advanced backends.
- High-Scale Data & Auth: Implementing high-performance OLAP solutions with ClickHouse and relationship-based access control (RBAC/ReBAC) using OpenFGA.
- Web Accessibility: Engineering automated auditing infrastructure and developer tooling compliant with WCAG standards.
- Agentic Workflows & Context: Advancing hands-on experience with LangGraph and Knowledge Graphs to build deterministic, stateful multi-agent systems driven by highly structured, interconnected data.

monitor-server (v2 architecture)
The core auditing backend for AccessMonitor — the official national web accessibility evaluation platform maintained by AMA (Portugal's Agency for Administrative Modernization).
Currently re-engineering the legacy system into a high-performance DDD modular monolith. The V2 architecture implements event-driven parsing pipelines via BullMQ, optimized state storage, and fine-grained relationship access control (ReBAC). -
accessmonitor-docker
A completely decoupled, light-weight orchestration service extracted directly from the core evaluation engine. It provides a production-ready, standalone Docker environment built to run automated accessibility audits independently, without the overhead of the main platform.
