Davin Maritza Alfarrezal

I engineer production cloud infrastructure, distributed systems, and applied AI applications.

Currently working as a Network Engineer at Phantomic Host, managing cloud infrastructure, bare-metal server provisioning, and network routing policies. Outside of core systems engineering, I build quantitative machine learning systems, autonomous multi-agent pipelines, and virtualization orchestrators.

Featured Projects

  • DareFX
    Institutional-grade autonomous AI forex auto-trader for EUR/USD. Combines supervised machine learning with Marcos López de Prado's Triple Barrier labeling, Purged Walk-Forward Cross Validation, and Deflated Sharpe Ratio (DSR) statistical testing, delivering a 2.95 annualized Sharpe Ratio and +30.31% out-of-sample return over 4,519 daily bars.

  • Crybaby
    Distributed Windows 11 PC cluster orchestrator and client Hyper-V remote virtualization manager. Pools consumer desktop hardware into an encrypted WireGuard mesh compute cluster without Windows Server licensing, complete with 1-click USB provisioning, dynamic vCPU/RAM resizing, and instant VM cloning.

  • OmniResearch
    Autonomous multi-agent deep research and fact-checking intelligence engine. Coordinates specialized planner, researcher, verifier, and writer agents across hybrid live web queries and corporate files with automated claim verification and empirical confidence scoring.

  • B2B Retention & Churn Intelligence
    Enterprise B2B customer retention and churn intelligence platform. Integrates machine learning classification with Explainable AI (XAI) feature attribution translated to executive business metrics, interactive what-if diagnostic stress-testing, and automated risk triage.

  • Multimodal Medical Imaging Pipeline
    An end-to-end deep learning pipeline for brain tumor segmentation and classification using the BraTS dataset. Deployed with a lightweight FastAPI inference service and Grad-CAM interpretability for medical imaging workflows.

  • Pterodactyl Espresso Theme
    An open-source dark warm-minimalist cockpit theme engineered for Pterodactyl Panel v1.11.x server management infrastructure.
