From on-chain messaging to AI-powered study apps: keep scrolling to travel the rail.
ReactA modern web app that lets users enhance photos with animated SVG text effects, creative gradients, and stylish visual elements. Built for performance, interactivity, and responsive design, SnapCharm showcases smooth animations and a minimalist aesthetic.
ReactCadena is a comprehensive Web3 ecosystem designed to showcase the transformative power of blockchain through a multi-functional dApp that integrates decentralized messaging, secure national budget tracking, and immutable voting systems. The platform features a private, peer-to-peer messaging interface that eliminates centralized oversight, alongside a pioneering "National Budget Tracker" that utilizes blockchain’s transparency to provide citizens with real-time, tamper-proof audits of government spending. Additionally, Cadena incorporates a decentralized voting module that leverages smart contracts to ensure electoral integrity and a fintech layer for managing digital assets, all unified within a modern Next.js interface to prove how decentralized technology can solve real-world problems in governance, communication, and finance.
React NativeYuwi is a warm, lightweight study app built with Expo and React Native. It is designed to make capturing source material, turning it into text, and generating quizzes feel straightforward instead of technical.
PythonA webcam-powered Tetris game controlled entirely by computer vision. Play using hand gestures via MediaPipe tracking with both desktop (Python/OpenCV) and web (Django) versions.

Moments, milestones, and lessons from my journey, pulled live from my LinkedIn, one post at a time.
A few hours before my first hackathon, I was deep in recovery mode fixing my Arch Linux setup. I pushed through, showed up, and walked away as champions of the Agentic Football Cup before college.
Excited to share that I've been selected as a Google Cloud Arcade Facilitator 2026: deepening my skills in Google Cloud and helping others level up too.
We built Sinta, an automated registrar powered by Agora Conversational AI and FaceIO. Voice enrollment, facial verification, and automated document requests. Top 10 finalists, one of the youngest teams there.
Proud to share that our team, Squad 3, is a finalist at Startup QC and the StartupQC Student Competition: even before officially kicking off.
As an indie developer, I've always believed powerful study tools shouldn't be locked behind expensive subscriptions. That's why I built Yuwi: local-first AI for students.
Earned the Google Cybersecurity Professional Certificate (v2): strengthening my knowledge of security fundamentals, threat detection, and incident response.
