Solo full-stack developer — I ship small, sharp products. Fast, cheap, and end-to-end.
🌐 elolin.com · 📫 dev.elolin@gmail.com
Over the last couple of months I shipped eight small products — an AI photo app, a family health vault, a crowd-testing marketplace, a desktop design tool, a browser game platform, and a few developer tools — for under ten dollars, most of them quietly humming on a Raspberry Pi in my living room.
Here's the honest part: building them was the easy part. Getting people to care is the real work, and I'm still learning that one in public. So I build the boring foundation once — one account system, one billing spine, one database — and then move fast on top of it. Local-first, cheap to run, no team, no investors. I own every product from the first commit to pricing, launch, and the 2 a.m. bug report.
Everything below is live, runs on one shared foundation, and is built + operated by me alone — under one login at elolin.com.
| Product | What it does | Stack · Model |
|---|---|---|
| 🎨 PhotoAI | Upload a selfie → ID photo, avatar, pet portrait or character art in seconds, no prompt-writing. Photos are discarded the same day. | Next.js · self-hosted (Raspberry Pi) · credit packs + subscriptions |
| 🎮 EloGames | Instant-play web game platform, led by my self-published flagship Lifeverse — a life-simulator you replay across parallel worlds. | Next.js · Cloudflare · self-operated ads + cross-promo |
| 🩺 KinMate | A private, local-first family health vault — keep lab reports, medical records & pet health on-device, with AI that explains them in plain language. | Flutter (iOS / Android) · on-device first |
| 🧪 TestHive | A crowd-testing marketplace — developers launch test campaigns, testers earn through an in-app credit economy, with shareable public reports. | Next.js · Supabase · in-app currency + commission |
| 🖥 Zivoe | A desktop AI industrial-design tool built to spark ideas — turn a rough concept or reference image into product hero shots & three-view drawings. | Flutter + Rust core · offline licensing · Win / macOS |
| 🌐 EloLin Domains | Claim a free sub-domain and manage its DNS yourself, from a simple dashboard. | Next.js · Cloudflare |
| 🔧 mv3migrate | A CLI that drags Chrome extensions from Manifest V2 → V3 — scans, applies codemods, and writes a migration report. | Node CLI · self-hosted docs |
| 🔌 Onrix AI | An OpenAI-compatible chat + image API — point your existing OpenAI SDK at it and build. | Cloudflare · edge |
| 🔐 accounts.elolin.com | The single sign-on layer that ties the studio together — one login across every product. | Cloudflare · OAuth · session & device management |
A local-first AI agent that learns from every task and gets out of your way.
Most AI assistants are amnesiacs — every session starts from zero and you re-explain the same things forever. That bugged me. EvoClaw runs on your own machine, plans, runs tools, and keeps going until the job is done — then distills what it learned into a reusable skill on disk, so the next similar task is shorter and cheaper. One Rust binary, ~8K-LOC core, zero telemetry, everything under ~/.evoclaw/.
🦀 single static binary · 🌳 skills that graduate through a five-state lifecycle · 🔐 secrets never leave the machine · 🔌 works across 7 ACP agents, 7 MCP servers & 17 model vendors
🌐 Website · 中文文档 available · brew install via homebrew-tap
Also on GitHub:atlassian-rovo-agent-mcp (a sane local MCP over Atlassian Rovo) · skill-xiaoshuo (a 40-step Chinese-novel writing workflow) · Work-assistant-skill (morning briefs & auto reports)
- Fix it, don't route around it. When a tool is slow or flaky, I'd rather rebuild it right than fight it forever. Reliability is a feature.
- Fast & effortless. Sub-second response, sane defaults, one command instead of ten. The best tool is the one you stop thinking about.
- Local-first, cheap to run, no telemetry. Your data stays on your machine; my infra bill stays near zero.
- Ship, then listen. Real users find the bugs I never would. I launch early and fix in public.

Building is the easy part. If you've figured out the getting-people-to-care part — I'd love to hear how.
