Project: Built a TypeScript Telegram bot for searching across folders and conversations — includes automated action item and calendar event detection. Designed for community managers and DevRel teams managing high-volume developer channels.

Tech: TypeScript, Node.js, Telegram Bot API

Note: Keyword search across message history, direct message deep-links, time-range filters, calendar event extraction, and action-item detection—built for real workflow in busy channels.

Project: Winning hackathon project at ETHWarsaw: Valspin—insurance and swap-style products to hedge ETH staking reward variance for validator operators, with Request Network–style settlement flows in scope. Includes Flask APIs for yield, swap, and insurance pricing plus an experimental live deployment.

Tech: Python 3.10, Flask, React, Material UI (MUI), NIVO charts, HTML/CSS

Note: Companion Python notebooks and sample curl endpoints document the modelling; if the hosted build hits CORS issues, the repo suggests Firefox or running locally (Flask + npm start).

Project: EthGlobal Istanbul 2023 build: SaferBridge explores a trust-minimized L2→L2 flow that moves value through L1 using each chain’s native bridge messaging—batching users to amortize gas (normal vs. fast modes) instead of relying on typical third-party relayer/LP bridge assumptions.

Tech: React, Redux, React Router, Ethers, Material UI, Solidity, Wagmi / Viem

Note: Hackathon prototype; the repo is explicit that this is not production-hardened code. The demo focused on proving the batched L2→L1→L2 steps on Sepolia test paths (e.g. Scroll) rather than two separate mainnet L2s.

Project: Minting non fungible ERC721 tokens based on #HEX color inputs by user

Tech: React, Solidity, Mocha, Chai, Ganache

Note: Giving user the ability to mint tokens using tested OpenZep contracts and using web3 imports with #HEX color inputs. Currently running off Ganache for testing.

Project: A gesture-driven knowledge graph interface. Point, pinch, and drag information nodes around your screen using your webcam and hand tracking — no mouse required. Nodes connect automatically through shared tags, building a visual web of linked ideas in real time. Mouse fallback always available.

Tech: React, Vite, JavaScript, MediaPipe Hands, Canvas API

Note: Built with MediaPipe Hands running in-browser via WASM. Supports pinch-to-grab, pinch-to-pan, and two-handed pinch-spread zoom. A debug panel (D key) exposes live hand landmark data for calibration. Node positions reset on refresh — persistence not yet implemented, which is either a bug or a feature depending on your philosophy.

Project: Deepscry (Scry) is a Magic: The Gathering deck lab—import a Commander decklist, simulate opening hands, and inspect mana curve, color spread, and draw probabilities. Compare your deck to benchmark metas (from precon-style through cEDH-style), review on-curve mana odds, and tag cards (ramp, interaction, draw, wincon) so the math matches how you actually play the deck.

Tech: Next.js, TypeScript, Tailwind CSS

Note: AI-assisted deck insight is on the roadmap; today the app focuses on simulation-backed stats, charts, and probability views for real decklists.

Project: Showcasing our solar system along with real time tracking of the ISS via API calls

Tech: React, ThreeJS, iss-api

Note: Fully responsive across desktop, tablet, and mobile

Project: Real time face recognition utilizing canvas.

Tech: React, JavaScript, face-api.js (tensorflow), and ThreeJS

Note: Please allow camera usage. You are able to navigate the space/field clicking + holding outside the white parameters.

Project: A single-page coffee brewing calculator built to help dial in batch brew and espresso recipes. Estimates brew ratio, TDS, predicted extraction yield, water temperature, grind size, and brew time — then visualizes multi-stage pour schedules with cumulative volume and flow-rate diagrams. Includes a countdown brew timer, brew journaling, custom recipes, and grind notes scoped per method.

Tech: React 19, Vite, JavaScript, CSS, localStorage

Note: Built around Coffee Spec brewing method ratios (V60, Chemex, AeroPress, Cold Brew, Espresso, and more). All extraction/TDS/yield numbers are predictive models, not lab measurements — but they'll get you closer to a good cup than vibes alone.
