CutiePi is an open-source project for a tablet based on Raspberry Pi CM4 and Qt Framework.

I contributed to the UI Shell development using Qt QML and some features that include a microcontroller, such as battery monitoring. It ended with a successful fundraising campaign that enabled mass production of the 1st batch.

An interactive platform designed to help toddlers learn numbers and alphabets through engaging, easy games, colorful animations, and audio cues. I implemented it mainly for my 2.5-year-old daughter (Danya) when I noticed she was interested in reading. I brushed it up a little and deployed it as a small educational platform, but it is still considered a project in progress. My QA team (daughter) was absolutely faster than my dev team (me).

A real-time video processing to display multiple effects, taking into consideration high quality and performance. This includes a large amount of WebGL and Shaders. The product is to run on multiple platforms and environments.

Built a lightweight Chrome extension that displays live and recent NBA game scores from the last 24 hours using the official NBA CDN feed. Designed a unique no-spoiler mode so users can check game status and excitement level without revealing final scores. Implemented efficient real-time fetching, dynamic sorting, and a clean UI focused on simplicity and privacy.

I built a real-time, map-driven music analytics experience using React, Next.js, deck.gl with Mapbox GL, and custom WebGL shaders. I designed the end-to-end flow, which involves ingesting events through Supabase, deriving venue timelines, and rendering animated routes that keep the camera centered on the active leg. I implemented a teardrop-trail shader for flight arcs via luma.gl shader injection, along with precise camera choreography (jump, ease, and fit) for narrative transitions. I also profiled and optimized performance by debouncing updates, quantizing Redux dispatches, memoizing datasets, minimizing layer update triggers, and removing flicker on intersecting circles—delivering smooth, production-ready geovisualizations at 60 frames per second on large, live timelines.

Designed and built a full-stack collaborative finance application that enables multiple users to manage shared accounts, submit transactions, and approve or reject them through a unanimous voting workflow. Implemented real-time balance tracking, role-based permissions, analytics dashboards (monthly summaries, balance over time), Google OAuth authentication, and a scalable user directory system. Focused on data integrity, edge-case handling, and clean state management across complex user interactions.
