    <h1>Understand before adopting.</h1>

    <p>5sigmas is a technical library about artificial intelligence. Its goal is to turn papers, repositories, benchmarks and engineering decisions into explanations that remain useful after model names change.</p>

    <h2>Who writes it</h2>
    <p>I am <strong>Francisco Maldonado</strong>, a graduate in both Physics and Mathematics. I design and build production AI systems, from voice assistants to computer vision and real-time systems.</p>

    <h2>How the work is done</h2>
    <p>Each piece starts with a question, goes to the primary source, explains the mechanism and ends by making the limitations explicit. Facts, inferences and estimates are treated as different things.</p>

    <h2>Formats</h2>
    <p>Short explanations introduce an idea. Interactive visuals make the mechanism manipulable. Series build the complete mental model. Technical notes turn that knowledge into architecture and operational decisions.</p>
