I'm Jim, a Melbourne-based indie developer. Over the last year I've shipped five small web projects across AI tools, subscription management, Hong Kong investing, crypto research, and daily puzzle games. Here's a quick walkthrough of each, what problem it solves, and what stack it uses.
1. OpenAI Tools Hub
A free directory of AI tools with honest reviews and head-to-head comparisons. Covers ChatGPT, Claude, Cursor, GitHub Copilot, Midjourney, and 50+ other tools. Built as a Next.js 15 app on a VPS, with a Supabase-backed blog pipeline so I can publish new comparisons without redeploying.

2. SubSaver
A subscription manager that shows you how to save on Netflix, Spotify, ChatGPT Plus, YouTube Premium, NordVPN, and 30+ other subscriptions through family plans, annual billing, and verified shared plans. Runs on Cloudflare Workers via OpenNext, with Supabase Postgres for the content tables.

3. Low Risk Trade Smart
Hong Kong ETFs, HK IPO strategies (打新), LOF premium arbitrage, and low-risk trading guides for Asia-Pacific investors. Trilingual (English, Simplified Chinese, Cantonese). Also a Next.js site, with a DB-driven catch-all route for the multi-locale blog.

4. AlphaGain Daily
Daily crypto news, DeFi updates, macro research, and long-term portfolio insights. Covers Bitcoin, Ethereum staking, Solana, and the major L1/L2 ecosystems. Prisma + Postgres for the news feed, and a lightweight editorial workflow so I can post while reading my feeds in the morning.

5. LevelWalks
A free daily puzzle and brain training platform featuring logic grid puzzles, word games, sudoku, nonogram, and a MindSort solitaire variant I built for seniors in my family. Cloudflare Pages + static JSON for levels and blog posts. Zero runtime server, which keeps latency and cost low.

I'd love feedback on any of these — especially from other indie builders. What stacks are you running, and what do you wish I'd built differently?
