01 / Evidence

Evidence with clear boundaries

Public screens come from real products. Private tools use synthetic demonstrations or sanitised diagrams. Records are validated before publishing and never expose lab URLs, credentials or household data.

EmpresaDB

Company search, sector context and territorial insight brought together in a fast, verifiable public product.

The problem

Portuguese company information exists, but it is fragmented across registries, classifications, territories and sources with different update cycles.

What I built

I built a platform that resolves identities by tax number, preserves provenance, and composes company search, sector and municipality pages, reports and analysis tools.

Outcome

A fast, indexable and free public product backed by reproducible pipelines, release validation and rollback.

  • React
  • FastAPI
  • SQLite

Market intelligence

Fragmented listings turned into comparables, trends and decision signals for opaque Portuguese markets.

Open project details

The problem

Listing portals expose inventory, but they do not explain what is overpriced, what is accelerating or what is genuinely comparable.

What I built

I built resilient collection, normalisation and comparison models, with a public property-market view and private operator cockpits for deeper analysis.

Outcome

A reusable foundation for tracking supply, price, liquidity and opportunities, with a firm boundary between the public product and operator tooling.

The problem

Reviewing invoices and tax sources is repetitive, error-prone work involving information that should not leave the browser without a clear reason.

What I built

I built a Chrome MV3 extension with explicit authorisation, local validation, temporary storage and strict contracts for any aggregate contribution.

Outcome

A guided review flow that reduces manual work without asking for tax credentials or turning individual records into a remote product.

Conta Luz

A household tool that reads public tariffs, compares scenarios and keeps invoices and consumption away from the public Internet.

The problem

Comparing electricity plans means combining tariffs, contracted power, time cycles and consumption patterns without handing household data to another public service.

What I built

I built a private comparator with public ERSE tariff ingestion, scenario modelling and access restricted to my personal network.

Outcome

A repeatable, auditable household decision with automatically refreshed offers and no public surface for household data.

Web delivery for local businessesActivePublic

d1060 website factory

A component, content and publishing system that turns a business brief into a fast, clear website built to convert.

Open project details

The problem

Many local businesses are stuck with slow pages that are hard to maintain and fail to present a clear proposition to mobile visitors.

What I built

I created a reusable foundation for discovery, editorial structure, responsive design, forms, privacy, technical SEO and Cloudflare publishing.

Outcome

Distinct websites on a consistent foundation, with low operating cost and a much shorter delivery path than rebuilding every project from scratch.

Open project details

The problem

A traditional online shop did not match a B2B sale built around customisation, quantity, negotiation and partner-supplied catalogue data.

What I built

I reframed the experience as an Astro catalogue with search, categories and quote requests, backed by a separate product import and management API.

Outcome

A faster storefront aligned with the real sales process, without the operating weight of the previous WooCommerce setup.

Operations, publishing and observabilityActivePrivate, sanitised evidence

Automation platform

The private foundation that turns independent applications into operable, observable and recoverable services.

The problem

A growing product estate becomes fragile when every service invents its own deployment, secrets, monitoring and recovery model.

What I built

I standardised containers, private networking, immutable images, pipelines, health checks, timers, alerts and cockpits that connect technical state to operational context.

Outcome

More predictable delivery, less public exposure and recovery based on known artefacts instead of improvised intervention.

The problem

The previous WordPress site was heavy to maintain and did not provide a simple foundation for the association's regular communication.

What I built

I migrated the structure to Astro and Cloudflare Pages, reorganised the content and prepared protected forms for low-cost operation.

Outcome

A fast, accessible preview ready for content review, final imagery and client approval before the domain cutover.
