👋 Who am I, and where am I from?
I'm Jong-Ha Ahn (a.k.a. Mr. Latte ☕) — an independent software engineer based in Seoul, South Korea.
Since 2002, I've been shipping web, mobile, and cloud products end-to-end — from problem definition to launch and operations. Over the past 20+ years I've delivered 80+ projects, launched 9 of my own services, and authored 4 patents and papers, while writing technical content since 2005.
Trends change. The way you actually finish things doesn't.
You can find more about me at mrlatte.net.
🛠 What am I working on?
Featured open source
The repos I'm currently building, maintaining, and shipping — old and new:
lipcode (Rust) — A coding agent that lives in your terminal. Local-first via Ollama (your code never leaves your machine), with optional cloud fallback through OpenRouter. Multi-agent orchestration, cost-aware model routing, single binary, <20ms startup.
inverseone-cli (Rust) — Market data for contrarian minds, straight from your terminal. Stock quotes, world indices (KOSPI, S&P 500, Nikkei…), FX rates, and commodities — no API key, no config. Powers the InverseOne platform. Available on crates.io.
redmine_vote (Ruby) — A Stack Overflow-style up/down voting plugin for Redmine. Long-running maintenance project, still installed by teams who run their own Redmine instances.
jquery-jsontotable (JavaScript) — Convert JSON into HTML tables with a single jQuery call. One of my earliest OSS projects and still my most-starred — a reminder of how long this work has been going.
You can see the full picture across 103 repositories at github.com/jongha.
Products I currently design, build, and operate
I'm running 9 services in parallel under the Mr. Latte brand, across fintech, social, productivity, gaming, travel, education, and talent matching:
Fintech
InverseOne — Contrarian investing intelligence turning oversold-rebound signals across KR/US/JP/crypto markets into quantitative cues (2024)
Platform & Discovery
Libsac — A daily opportunity feed that organizes scattered contests, events, performances, and lectures into actionable items (2024)
GameSnapshots — A visual-first game community where player screenshots and reactions help you discover what to play next (2024)
Hizine — A film-tourism platform that maps scenes from movies and dramas to real travel itineraries (2024)
Education & Talent
Reputo — A career exploration platform turning students' vague job aspirations into concrete stories, roadmaps, and mentorship paths (2026)
StartupXO — A human-first platform matching startups and AI teams with pre-vetted freelance specialists (2026)
Social
Typdit — A text-first social platform focused on the authenticity of writing and the density of conversation, without images or video (2026)
The Weple — A social lounge built around short check-ins, mood-based matching, and conversations that end naturally (2026)
Productivity
DeepThought — A browser-based mind map tool that turns scattered thoughts into visual structure in seconds, no install required (2026)
💚 Why your sponsorship matters
I maintain my open-source projects in the time left over from running products and client work. Your sponsorship buys back that time — so issues get answered faster, plugins keep working with newer versions, and new tools actually ship instead of staying in my drafts folder.
Concretely, your funds go toward:
⏱ Maintenance time — triaging issues, reviewing PRs, and keeping plugins compatible with new versions of jQuery, Redmine, and Node
🤖 New OSS tools — especially around AI-assisted development workflows and product automation
🌐 Infrastructure — servers, domains, and developer tools that keep the projects running
📚 Free technical writing & tutorials — in both English and Korean, for the wider developer community
Even a $1 sponsorship is a real signal that this work is worth continuing. Thank you for considering it 🙏
