Safafish — independent software
I design, build, and operate complete products end to end — Go & Rust services and the cloud infrastructure they run on, plus the native iOS and macOS apps on top. Safafish is my independent studio of one.
Innovative tools designed to spark your creativity and accelerate your learning
Apps that get something made — translate a call, run a server, take a note, learn a word, direct a film.
A live interpreter for Mac: speak naturally, see the translation instantly, and hear it read aloud. Choose private on-device AI, the cloud, or your own services.
A keep-alive SSH & Mosh terminal for iPhone and iPad, with a Mac companion for remote desktop. Roam across networks, reattach sessions, and keep your servers a tap away.
Handwritten notes and typed Markdown in one notebook. Custom Metal brush engine with 7 pens, reference workspace for side-by-side study, and local-first storage.
Your personal AI learning partner for Japanese. Master vocabulary with AI-generated sentences, smart spaced repetition, and immersive study modes.
Describe a scene in one sentence and it comes back as a script, a cast and a shot-by-shot storyboard. Direct the shots you care about, generate the picture, music and voice, then cut it into a short film you would put your name on.
Apps built around other people — a voice to talk to, friends to play with, a companion on your screen.
Find another possibility. Picture someone you cherish, a star you adore, or a future not yet here — meet them in a parallel world and watch the beautiful "what ifs" come to life.
Murder-mystery and Werewolf party games you can play right in the browser. Gather friends into a room, pick a mode, and play out the night together — nothing to install.
A 3D desktop pet that walks around your screen, naps when you're busy, and wakes up grumpy when you poke it too much. Autonomous behavior engine and expandable cloud skills.
Apps for the everyday — your weight, your eyes, the photos you keep.
A record for a GLP-1 course of treatment: a forecast anchored to published studies, weight, doses and costs on one timeline, and a history that survives every pause.
Gentle guided eye breaks for screen-filled days. Relax tired eyes, ease dryness, and refocus — most practices take under two minutes.
Reality is boring. Your imagination is not. Turn your vaguest daydreams into visual masterpieces with AI-powered image generation.
About
Cloud & Backend Engineer who ships full products
Safafish is an independent software studio focused on practical, carefully built apps across cloud services and native Apple platforms.
Recent work spans a keep-alive SSH terminal with full Mac remote desktop (SharkTTY), AI creative and learning apps (Kaka Camera, AiWords, AlterEcho), and the relay and gateway services that power them.
From infrastructure to interface, I take features all the way to production — and stay responsible for them in the wild.
Not just code: I deploy, monitor, and operate the services, so I design for real networks, real cost, and real failure.
Pixel-level Swift interfaces on top of hand-tuned Rust systems and encryption — at home across the entire stack.
One engineer across the whole stack — from the cloud that runs the service to the pixels on the screen.
Design and operate the servers behind every app — Docker & Podman with Traefik on Oracle Cloud, automatic Let's Encrypt TLS, and self-hosted relay & gateway nodes across regions.
Production services in Go and Rust: REST APIs, account & token auth (JWT and HMAC), usage metering and quotas, SQL schema and migrations, and clean control-plane / data-plane splits.
Native Swift & SwiftUI across iPhone, iPad, Apple TV and Vision Pro, plus macOS menu-bar apps — StoreKit, Keychain, ScreenCaptureKit, VideoToolbox and Metal.
Low-latency streaming and transport — QUIC and WebSocket signaling, end-to-end encryption, and Rust↔Swift FFI shipped as prebuilt xcframeworks.
LLM-powered features and image generation in users' hands — AI companions, Japanese learning with spaced repetition, and generative photo tools.
The full loop, solo: product design, 6-language localization, App Store submission and compliance, landing sites, and ongoing support.
