Web Security Auditor 🛡️ — Defensive Audits (Web Coming Soon)

Skill.MD & Chrome Extension

I think cybersecurity will be the hottest topic of the year as better and better models uncover vulnerabilities no one knew existed. So I built a defensive web security auditor: a Chrome extension + skill that scans the current page or a supplied URL, checks browser-visible issues and headers, crawls a few same-origin pages, and can optionally use OpenRouter for deeper analysis. The full web experience is coming soon — the extension and skill are live on GitHub.

Pomodoro Pill 🍅 — Floating Timer on Your Mac

macOS App

I built a native macOS companion for deep work: a draggable glass “pill” with Pomodoro countdown, daily goal and sprint task fields, review prompts, and a lightweight outcomes journal. Menu bar control, Option+Space to jump into the fields — the kind of timer I actually keep on screen.

World Sim 🌍 — Personas React to Your Post

Web App

I wanted to stress-test ideas the way different audiences might — before you hit publish. World Sim lets you write a LinkedIn-style post, then runs dozens of demographic personas through an LLM (OpenRouter) so you can see reactions, comments, and intensity on a globe view. It’s part toy, part mirror for how a message might land.

Reel Deal 🎬 — AI Video Workflows for Videos That Are Actually Good

Web App

I've been experimenting with AI-generated videos that are actually good, not just uncanny demos. Reel Deal is the workflow builder I made to chain prompts, title cards, voiceovers, video generation, beat sync, and stitching into short-form videos I would actually post.

Claude Code Tab Reminder 🚀 — Know Which Terminal Is Which

CLI Utility

When I have 5 Claude Code terminals open, they all start to look the same. So I built a tiny status line tweak that shows the current folder right in Claude Code. Every tab gets a fast visual identity tied to the project you're actually in. One paste install, zero dependencies, way less chaos.

TimeBack ⏳ Block Shorts, Feeds & Mass-Unsubscribe from Gmail

Chrome Extension

I hate short-form content and algorithmic feeds. They turn attention into brain rot. So I built TimeBack: a Chrome extension that blocks YouTube Shorts, the home feed, LinkedIn noise, and lets you mass-unsubscribe from Gmail. Fewer distractions, less inbox clutter, more life.

TalkType 🎙️ — Free Mac Transcription, the Wispr Flow Alternative

App & Website

I believe the future of human interaction is talking. It's more natural, and you can communicate at a much faster rate than typing. So I built TalkType — a free, open-source alternative to Wispr Flow. On-device speech recognition, 11 languages, total privacy. Your voice never leaves your Mac.

ARR We There Yet? 📈 — Your VC News & Deal Intelligence Hub

Web App

I love startups. But it's hard to keep up with such a fast-moving space. ARR We There Yet? is a tool for VCs and founders to track the latest funding rounds, search your LinkedIn network for warm intros, and analyze startups and unicorns — all in one place.

Tinker RFT 🧠 — Improving Qwen4B at Grade School Math by 0.8%

Research

I've been interested in GRPO and RFT for a while — it's often a precise balance, improving one benchmark without making another worse. I ran RFT on Qwen 4B to see what was possible. Result: +0.80% on math, from 89.2% to 90.0%.

TubeLLM 🚇 — Offline AI for the London Underground

App & Web App

On the London Tube there's zero signal — so I can't use AI. I built TubeLLM to fix that. Download a local LLM once, then chat with it completely offline. No Wi-Fi, no data, no cloud. Just answers, even underground.

ClosedLoop ☕ — Let Claude Code Access Your Browser

Skill.MD & MCP

I was tired of being a screenshotting intern for my AI tools — they couldn't see the page. So I built ClosedLoop: a skill + Chrome extension that gives your agent direct control of a live tab. It navigates, clicks, reads its own errors. Drink coffee, not error logs.

Calorie AI 💪 — Log Meals, Hit Macros, Track Streaks

App & Web App

I'm getting married this summer and wanted to show up in shape. So I built my own fitness app — log meals, hit your macros, track streaks. AI-powered calorie tracking and workout planning. No fluff, just what I needed.

Best Olive Oils Ranked 🫒 — Scientifically, Not Sponsored

Website

I'm from Spain and grew up with olive oil. I'm convinced it's one of the healthiest things you could have. This site ranks the absolute best olive oils scientifically. Bryan Johnson says it's the #1 thing he takes.
