Products

What I've built

    Renderlog

    A bilingual technical blog about frontend engineering, written from production experience, refactors, and decisions that only appear after years maintaining real software.

    Problem
    A lot of Spanish frontend content is shallow, translated without context, or disconnected from real production decisions.
    User
    Frontend and full stack developers looking for practical judgment about React, Next.js, Vue, performance, architecture, and i18n.
    Solution
    A bilingual blog with articles written from direct experience, an editorial point of view, and topics that connect code with technical judgment.

    Outcome
    A personal platform that demonstrates technical communication, senior judgment, and lightweight infrastructure operations with Raspberry Pi and Cloudflare Tunnel.

Process

How I work

Principles that guide my product, architecture, and delivery decisions

  • Ship small, learn fast

    I validate with real users before adding debt or unnecessary complexity.

  • Simple, observable, maintainable systems

    I choose architectures teams can operate, debug, and evolve without heroics or tribal knowledge.

  • Modernize without breaking the business

    I migrate legacy platforms pragmatically with feature flags, incremental delivery, and controlled risk.

  • Bilingual product with real context

    I design Spanish and English experiences around users, tone, and cultural constraints—not translation alone.

  • AI and automation with purpose

    I adopt new tools when they remove real friction for users or teams, not because of hype or to replace judgment.
