01Selected work

Two modes of building. One standard: useful software, finished properly.

GROUP 01

Stelnyx — Developer Infrastructure

Developer tooling for understanding, securing and improving software systems. Deterministic, local-first, CI-friendly.

  1. LuxScope

    Codebase intelligence scanner. Deterministic 0–100 score, risk-ranked files, architecture map, generated handoff docs. Local-first.

  2. LuxFaber

    Agent-readiness (AEO) scanner. Scores how well AI agents — GPTBot, Claude, Perplexity — can crawl and operate a site.

    dev tool · scanner · Proprietary private · early access

  3. LuxAbility

    Web accessibility scanner. Detects WCAG issues, surfaces barriers and prioritizes fixes for more inclusive digital experiences.

  4. SecGate

    One-command security gate. Aggregates Semgrep, Gitleaks, OSV-Scanner, Trivy and npm audit into one deterministic report and a CI exit code.

  5. ApiGate

    Static API surface auditor. Enumerates HTTP endpoints across Express, Fastify and NestJS, classifies auth posture, diffs against OpenAPI — no running server.

02About

I have spent 20+ years building software and leading delivery across distributed, cross-functional teams. I can move between architecture, hands-on implementation and technical leadership without losing sight of the product or the people using it. Today I combine full-stack TypeScript, edge-native infrastructure and disciplined use of AI coding agents to move faster while keeping engineering judgment, quality and ownership firmly human. I work comfortably across English, Spanish and Portuguese, and I stay with the work until it is shipped, understood and maintainable.
