hello@glpecile.xyz · Buenos Aires, Argentina

* roles

  1. Software / Frontend Engineer @ POAP - Proof Of Attendance Protocol

    Buenos Aires · Hybrid

    • - Build and own reusable React/TypeScript components and shared UI patterns for POAP — the web3 protocol for issuing digital collectibles (NFTs) — keeping the interface consistent and high-quality at scale.
    • - Ship features for POAP Home, POAP's React Native mobile app, across iOS and Android — sharing TypeScript patterns and design language with the web surfaces.
    • - Prototyped an unreleased location-based game in Expo / React Native with real-world Mapbox maps integration, and distilled the map-engineering patterns into a blog post.
    • - Ship polished, high-traffic collectible (NFT) interfaces end to end — from UI implementation through code review and release — improving reliability, performance, and product feel.

  2. Teaching Assistant @ ITBA - Instituto Tecnologico de Buenos Aires

    Buenos Aires · Remote

    • - Led technical sessions and code reviews on multiplatform mobile development, instilling production-grade engineering best practices.
    • - Mentored students through architecting and shipping apps across iOS and Android.

  3. Software Engineer @ Aligned

    Buenos Aires · Hybrid

    • - Designed and built the user-facing block explorer for zero-knowledge proofs in the Aligned verification layer — turning dense, real-time on-chain proof and batch data into a clear, legible interface.
    • - Owned the explorer frontend from concept to production, working mostly in Elixir (Phoenix) against protocol APIs.
    • - Built initial versions of Aligned's Next.js landing sites and an unreleased token bridge from Starknet to Ethereum and zkSync.

  4. Frontend Engineer @ Constellation Network

    Remote

    • - Designed and built Courtyard, an anonymous chat app authenticated with the Constellation web wallet — wallet-based sign-in was novel at the time — owning the product UI end to end.
    • - Built the app with Next.js, TypeScript, and Zustand, shipping complex chat features such as a draggable picture-in-picture view and a queue system.

  5. Social Media Designer @ ITBA Computer Society

    Buenos Aires

    • - Produced brand and design assets for a student technology community.

* 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. shinobu · React Native / Expo / TypeScript

    • - Building a DB-less, cross-platform media tracker (iOS / Android / web) — log a movie, episode, or manga chapter once and it fans out to every connected tracking service (Trakt, AniList, Letterboxd), with the same providers aggregated back into one feed.
    • - Modern Expo stack — expo-router, React 19 with the React Compiler, TanStack Query, Effect, Reanimated, and Tailwind-based styling — from a single TypeScript codebase.

  3. lugia · React Native / Expo

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

  4. 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.

  5. 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.

  6. srt-cli · TypeScript / Bun

    • - Authored and published an open-source CLI that converts plain text into .srt subtitle files.

  7. ITBA Systems Coursework · C / Java / PostgreSQL / Redis

    • - Cryptography & steganography tooling, a multithreaded socket server in C, distributed object computing in Java, and a Postgres/Redis-backed data platform.
