FIFA

A FIFA 2026 planning tool that helps fans search participating countries, players, venues, and host cities to find match dates, opponents, stadium locations, and travel-planning context. The MVP uses scraped World Cup data, a local SQLite database, and an interactive React frontend so users can search teams like USA, Germany, Japan, or cities like Dallas and get match schedules, scouting notes, and trip-planning results for flights and hotels.

CrossCheck is a Chrome extension and web app where a user highlights a claim or pastes a URL, then it uses Bright Data on the server to search Google/Bing results, fetch public source pages, and collect real evidence before giving a label like Supported, Disputed, Unverified, or Misleading Context.

Following the World Cup 2026 makes it difficult because of the different schedules of the game : some are late at night, some are in the morning.. I wanted to make sure I don't plan something else on the games that I'd like to follow ! I could use Bright Data for the scraping for data of who are broadcasting.

Upper extremity clinical decision support. This tool will help Occupational Therapists complete an upper extremity evaluation. I used Bright Data as the evidence acquisition layer. The app generates a provisional upper-extremity clinical pattern from OT/PT evaluation inputs, then Bright Data retrieves current public evidence and guidelines to support clinician review.

LinkedIn BS Detector is a Chrome extension that scans visible LinkedIn feed posts and overlays a small “BS score” badge on each post. The extension runs fully in the browser with no backend, no LLM calls, and no data collection. It uses deterministic scoring rules to detect classic LinkedIn writing patterns like buzzwords, vague achievement language, humblebrag phrases, excessive emojis, excessive exclamation marks, and generic motivational endings. It also reduces the score when a post includes more concrete signals, such as numbers, dates, technical details, specific project descriptions, or honest negative details like being laid off, rejected, failing, or struggling. Each badge shows a score from 0–100 and a label: - 0–25: Probably Human - 26–50: Mild LinkedIn - 51–75: Corporate Fog - 76–100: Peak LinkedIn On hover or click, the badge explains the top reasons behind the score. The extension uses Manifest V3, plain JavaScript, CSS, and a MutationObserver to handle LinkedIn’s dynamically loaded feed.

CellShift

Build a dashboard for drug target shortlisting for pharma companies. This is wrapped around our model, which achieves state-of-the-art performance for single-cell perturbation prediction. Using Codex we managed to build a platform that pharma scientists can use to see a ranked shortlist of target genes with predicted disease-state shift, priority score, confidence, risk flags, and suggested validation assays. To do that, they just need to input a disease context, control-cell gene expression states, and candidate genes.

WinCast watches Polymarket and Kalshi at the same time, strips the house margin out of both, fuses them into a single consensus probability that is sharper than either venue alone, and tells you the exact moment the two markets disagree enough to be worth trading using a novel regression model.

OpenAI CodexBright Data

A web app that aggregates Reddit vibes (using Bright Data Scrapper!) for work-friendly cafés in SF's Mission and SoMa neighbourhoods, displays them on an interactive map with scored attributes (WiFi, outlets, noise, aesthetic), and gamifies café hopping with a digital passport + punch-card system. Users earn stamps per visit and redeem points for real prizes (free drinks, charger loaners, merch). Instead of being a per cafe system, you get points for being a pro Cafe user! We can also expand this to allow cafes to get a lot of marketing through Instagram, twitter + more using Bright Data's platform.
