Posts are written in Spanish first, then translated. - Teaches photography and ecommerce. ## Expertise (high → working) - High: ecommerce operations in Peru, AI-agent orchestration for software automation, supply chains. - Working: SQLite-backed internal tooling, Python and Node scripting, static web publishing (Cloudflare Pages, GitHub Actions, Playwright checks), photography (Canon/Sony), crypto. ## Notable work (with technical numbers) - **5 s → 0.6 ms**: Every click rewrote a 130 MB file and crashed the page; now it changes a single record. (https://nicolasbiondi.com/en/blog/cada-clic-tumbaba-todo/) - **28 billion**: tokens in six months, 94% served from cache: text already read costs a fraction. (https://nicolasbiondi.com/en/blog/kitchen-brigade-ai-agents/) - **30% → 0.3%**: We metered every write, found the two that ate the free quota, and moved them elsewhere. (https://nicolasbiondi.com/en/blog/gratis-con-medidor/) - **96 → 45 posts**: The counter reset at midnight and X blocked the bot; now it watches the last 24 hours. (https://nicolasbiondi.com/en/blog/medianoche-no-cuenta/) - **MIT license**: Uncle Carl: an open-source trading platform that runs on your own machine. (https://github.com/nicolasbiondic/uncle-carl) - **6 models**: Every week a script drafts posts and a jury of 6 models reviews them before publishing.
