* projects

  1. glpecile.xyz — Personal site & design system · Astro / TypeScript / Tailwind CSS

    • - Designed and built this site as a hand-crafted component system — consistent type, color, and motion tokens driving every page from a single config.
    • - Engineered a custom CV generator that renders a typeset PDF programmatically (pdf-lib) from the same content source as the live site.
    • - Sweated the details: reveal/stagger animations, keyboard shortcuts, dark/light theming, and an /llms.txt export for agents.

  2. lugia · React Native / Expo

    • - Built a cross-platform (iOS / Android / web) blog application with Expo from a single shared UI codebase.

  3. Human-in-Picture — Privacy-Preserving CNN (Thesis) · Python / PyTorch / Concrete ML (FHE)

    • - Engineering thesis: a CNN that detects human presence in images while running inference entirely on encrypted data via fully homomorphic encryption (FHE) — no server-side decryption.
    • - Trained a PyTorch CNN and compiled it with Concrete ML (Zama) for homomorphic inference; benchmarked accuracy and latency across input resolutions (32–128px).
    • - Shipped an interactive proof-of-concept web app demonstrating end-to-end private inference.

  4. SIA - AI Systems · Python / NumPy / AI/ML

    • - Implemented perceptrons, search, and optimization algorithms from scratch in Python.
    • - Trained and evaluated neural-network and AI models across multiple problem sets.
