sawirricardo··on Ask HN: What are you working on? (August 2026)
Hi, i have been working on https://myvivaldy.com, it's my clinic/business OS in healthcare industry (is this what the cool kids say nowadays?), Id say it is like SAP made just for this clinic OS. Especially since the Claude Boom at Dec 2025, I intensely improve this clinic from simple reservation/encounter services into full-fledged clinic OS. Users are mostly employees and patients. mostly report positive feedback. and since this industry is highly regulated (Hi FHiR v4), with the help of AI I can fulfill any major concern and whip up PoC. I can also experiment with features which was previously not feasible due to time/energy/skill constraint. Whatever make sense for user experience imaginable is a few prompts away now.

Love to help others if one wants to build their own business OS especially if you're in medical/healthcare industry.

sawirricardo··on Show HN: Cozy Cafe – A browser-based idle clicker game, made with Claude Code
Built this with Claude Code Opus 4.5. It's an idle/clicker game where you run a coffee shop.

Tech: Pure HTML/CSS/JS, Web Audio API for sounds, localStorage for persistence, Stripe for payments.

The interesting parts: - Balancing exponential growth is tricky. Used cost multipliers (1.4x-1.8x per upgrade level) - Web Audio API can generate satisfying sounds with just oscillators - Prestige systems add surprising depth to simple mechanics

I asked Claude to just do this pretty simple - about 1200 lines of JS total.

Happy to chat about this new way of "we can just build it"
