Hi, I'm Ramine Darabiha
Founder · Product & R&D Leader
I've built consumer products downloaded billions of times.
I care about products that expand human agency, reward craftsmanship, and make difficult technology feel natural.
About me
I build products and product teams. My product sense runs from the system to the surface: I know architecture and UX from the inside, and I can do the work myself when needed. I get there early, often before there was a company to join: a cloud OS in 2008, IPFS in 2016, AI email agents in 2020, decentralized identity in 2021, agentic commerce in 2025.
I helped pioneer games as a service123, leading R&D and product on Angry Birds, Angry Birds Rio, and Fruit Ninja, 3 of the 10 most-downloaded games of all time456. I worked in live-games portfolios of 50+ titles with billions of downloads.756

AI-native product development
An archivist that proposes sourced changes. A music tool that people and agents can play. A Mac that becomes a room’s sound system. I build these products with AI across design, engineering and operation, and make the decisions that connect the technology to the experience.
- PartyParty: Public beta. Play audio from your Mac. Guests scan a QR code and listen on their own headphones. Native audio capture and LL-HLS streaming connect a Mac to iPhone browsers, over venue Wi-Fi or a cloud relay. No guest app or account. Public beta; mixed-path timing is still being resolved. Scope: Product strategy, interaction and visual design, native macOS app, Go streaming and relay architecture, guest web experience, Cloudflare infrastructure, testing, distribution, and operations
Visit product · Latest product decision · View source · Join the TestFlight beta - Darabiha: Live. Give a family archivist a document. Review the people, relationships and stories it finds. An agentic private family archive with multilingual evidence, deterministic reconciliation and audited proposals. Connected assistants suggest changes; family members decide. The public TreeTree sample uses invented records. My scope: Product strategy, archive reconstruction, data modeling, privacy and access design, interaction design, full-stack engineering, AI workflows, infrastructure, migration, testing, and operations
Try public sample · Latest product decision · View source - Retro Porting Toolkit: Live. Find the tools, native ports and people bringing older games to new hardware. A collaborative publishing system maps static recompilation across tools, runtimes, games and hardware. My work is the website, information architecture and editorial tooling; the community builds the recompilers and ports. My scope: Product, positioning, information architecture, design, web engineering, publishing system, and editorial workflow
Visit product · View source - Chiptunes.app: Live. Compose Game Boy music, edit every note, and share the song as a link or cartridge. A deterministic composer, register-level emulation and a cartridge compiler share one score. Browser-agent tools can compose, analyse and export through the same engine. Scope: Product, interaction design, audio systems, engineering, infrastructure, launch, and operations
Use it · Latest product decision · View source - ramine.net: AI-First Publishing: Live. Publish a body of work with its sources, working demonstrations and history intact. A typed content graph, deterministic two-site compilation and agent-operable editorial workflows produce this site. Citations, search, media and fully prerendered routes come from the same records. Scope: Research, product strategy, information architecture, design, engineering, infrastructure, QA, launch, and publishing operations
Visit product · Latest product decision - Spatial Gallery: Live. Walk through the work, open a project, and watch a talk inside the gallery. A dual-mode WebXR scene supports gaze and pinch on Apple Vision Pro, plus mouse and touch in a browser. Spatial interaction and the conventional portfolio share the same content. Scope: Product, spatial interaction design, WebXR engineering, performance, media delivery, and launch

Selected past works
- AI Store Manager: An AI agent built to run the whole business behind a page: catalog, checkout, shipping, fulfillment. A working MVP, ahead of the agent wave.
- Spatial Gallery: A dual-mode WebXR scene supports gaze and pinch on Apple Vision Pro, plus mouse and touch in a browser. Spatial interaction and the conventional portfolio share the same content.
- Chiptunes.app: A deterministic composer, register-level emulation and a cartridge compiler share one score. Browser-agent tools can compose, analyse and export through the same engine.
- Games as a Service: Built Halfbrick's product function and turned Fruit Ninja, Jetpack Joyride, and the whole catalog into live services. The flagship passed a billion downloads.
- Product on Angry Birds: PM on the biggest mobile game in the world: platforms, ads, location, partnerships, and a toys-to-life unlock years before Amiibo.
- ramine.net: AI-First Publishing: A typed content graph, deterministic two-site compilation and agent-operable editorial workflows produce this site. Citations, search, media and fully prerendered routes come from the same records.
- Identity Systems: User-owned identity, social-login wallets, and a gasless social rollup that Tezos core developers called the first of its kind.
- Retro Porting Toolkit: A collaborative publishing system maps static recompilation across tools, runtimes, games and hardware. My work is the website, information architecture and editorial tooling; the community builds the recompilers and ports.
- AI Email Agents: Rules, scripts, and actions that let software act safely on your inbox. An agent product shipped before agents were the pitch.
- Browser-Based OS: A web desktop with files, apps, publishing, and identity, used by roughly 72 million people before the browser-as-OS was a category.
- Decentralized Music & Social: DNS.xyz: one social login gave you a wallet you own, a portable identity, and a place to publish and sell directly to fans. Four surfaces, one platform on Tezos.
- PartyParty: Native audio capture and LL-HLS streaming connect a Mac to iPhone browsers, over venue Wi-Fi or a cloud relay. No guest app or account. Public beta; mixed-path timing is still being resolved.
- Darabiha: An agentic private family archive with multilingual evidence, deterministic reconciliation and audited proposals. Connected assistants suggest changes; family members decide. The public TreeTree sample uses invented records.
- Experimental Technology: 50+ prototypes across AR, procedural generation, new inputs, and the open web. R&D pushed until the novelty became play.
- Direct-to-Fan Music Platform: Artists publish, build community, and sell directly to fans. Some earned materially more here than streaming paid them.
- Smart Wallets: Sign in with Google or Twitter and get a non-custodial wallet you genuinely own. Account abstraction hidden behind a normal signup.
- Hyperminter: Drop in your art, edit metadata in bulk, mint the whole set in one click. The most-used batch minter on Tezos.
- Soundmojis: Collectible characters with sound, designed like premium toys you want on a shelf, not assets you wait to flip.
- The Consuming Shadow: Produced Yahtzee Croshaw's first commercial game, a Lovecraftian procedural horror. Very Positive on Steam, with one shot to get it right.
- A Change of Heart: A 48-hour jam win: an endless runner you steer with earphones in your pocket, used backwards as a motion sensor.
- Game Design for Music Drops: Leaderboards, collector tiers, and unlockable perks on a Kane Mayfield drop. Game design pointed at fandom.
Recent product decisions
- Kinship labels for a 426 person tree (2026-09-07): A family tree that explains how you are related, in English, Persian and French. Caching two graph walks brought a labelled canvas from 645ms to 37ms.
- LSDj export and import, verified in mGBA (2026-09-04): Take a generated song into a musician’s existing tools and keep composing. The export is checked by running LSDj in mGBA, not by trusting our own decoder.
- A 2.2 second split between the direct and relay paths (2026-08-11): A room should hear the same moment together. Real-player measurements found a 2.2-second direct/relay split and exposed a misleading test proxy. The timing limit remains open.
How I think about products
An agent should give someone more control, not ask them to surrender it. In Darabiha, a connected assistant can propose a change, but the family decides what becomes part of its history.
The interesting technology has to survive an ordinary moment: a guest locking their phone, a musician changing one note, a relative reading a name in their own language. That is where craft becomes a product decision rather than decoration.
At Halfbrick, I built a product team around frequent releases and reviews of what players actually did. I bring that same expectation to AI: make room to try things, put the result in front of people, and turn what fails into a better next decision.
