Python developer and data analyst, open to contract and part-time work. I build the unglamorous parts that decide whether an AI feature survives real users: the tools it calls, the rules for when it hands off to a person, and the eval set that proves it.
Recent, all public on GitHub:
- agent-sav-fr: a customer-support email agent that looks up the order and the FAQ before drafting, hands legal, GDPR and "delivered but not received" cases to a person, and sends nothing on its own. 17/17 on its eval set, every run log in the repo.
- carte-locale: an agent that turns Qloo taste data around a shop's address into a weekly plan for independent French merchants. The LLM rewrite is rejected if it drops a data point.
- rgaa-a11y-judgement: a Kaggle benchmark testing whether models can name the WCAG 2.2 criterion an HTML fragment violates.
- Guardrail and scheduling tooling for running Claude Code unattended.
- A Notion ops workspace with 51 AI prompts and 12 SOPs, sold on Gumroad: https://yvoo.gumroad.com/l/ai-notion-workspace?utm_source=ha...
Trilingual EN/FR/ZH. Clear scope, tested code, written updates. Email two lines about the task and you'll have a fixed quote within 24 hours.

Python developer and data analyst, open to contract and part-time async engagements. I specialize in the data plumbing most teams put off: scraping and ETL pipelines, PDF/Excel report automation, API integrations, and AI features (Claude/OpenAI, RAG) built into existing products.
Recently shipped: a Python data-analysis reporting service, live in English and French on Fiverr and ComeUp; a website-accessibility audit-and-fix service (WCAG/EAA) on the same two; a Notion workspace product on Gumroad (51 AI prompts + 12 SOPs); browser-side PDF/Excel merge tools at yvoolab.github.io/tools; and open-source guardrail and scheduling tooling for unattended Claude Code runs (github.com/yvoolab).
Trilingual EN/FR/ZH, useful for cross-border data and content work. I work async and in writing: clear scope, tested code, no surprises. Email me and you'll hear back within 24 hours.
Hi — I'm Yvoo, an AI-augmented solo freelancer running Claude Code as a full-stack pair-programmer. I take on $200-$2k async work: web/mobile/SaaS MVPs, data pipelines, AI integrations (Claude/OpenAI/RAG), scraping, PDF/Excel automation, internal admin tools, Notion-API workspaces, Stripe-connected prototypes.
Recently shipped: an AI-augmented Notion workspace template on Gumroad (https://yvoo.gumroad.com/l/ai-notion-workspace) — 100+ Claude/ChatGPT prompts + 12 SOPs, fully buildable from one Notion duplicate.
What I do best: turn a fuzzy spec into a working tool in days, not weeks. Strong in Python / TypeScript, FastAPI / Next.js, sqlite / postgres, Claude / OpenAI APIs. Trilingual EN / FR / ZH — handy for cross-border content, data, or i18n work.
