How I Built an Autonomous AI Refund Decision Engine with FastAPI, React, and LiteLLM

0
·1 views

Customer returns and refund requests are among the costliest operational friction points for modern e commerce platforms. Traditional solutions force businesses to choose between two undesirable extremes: Rigid rule engines that deny valid edge cases, frustrating loyal shoppers. Naive generative chatbots that can be easily manipulated through prompt injection, promising free money and unauthorized chargebacks. To solve this, I designed and built an autonomous AI Customer Support Refund System. It balances instant automated decisions with deterministic policy checks, velocity safeguards, and a

Your Database Will Leak Someday: Field-Level Encryption and Blind Indexes for PII with Python and PostgreSQL

Tuần này HN đang bàn rất nhiều về vụ rò rỉ dữ liệu ở Đan Mạch: thông tin cá nhân của 8,8 triệu người bị lộ. Đọc qua các vụ breach lớn vài năm gần đây, mình thấy kịch bản gần như lặp lại: lộ một bản backup, một bucket S3 cấu hình sai, một lỗi SQL injection, hoặc một tài khoản read-only của bên analytics bị lấy mất. Điểm chung là kẻ tấn công đọc được database ở dạng plaintext. Lúc đó TLS hay disk encryption cũng không giúp được gì. Bài này chia sẻ cách mình làm field-level encryption cho dữ liệu PII (email, số điện thoại, CCCD...) bằng Python và PostgreSQL.

Big marketplaces charged steep commissions and buried small sellers.

My job feed broke silently for 3 days. So I built a CI guardrail that fails the build when it happens again

My job feed broke silently for three days before anyone noticed. The board's API hadn't gone down — it had just started returning an empty data field where there used to be a list. My scraper kept running, my dashboard kept refreshing, and the count quietly dropped from ~340 jobs to 0. No alert, no error, no page. That's the class of failure that almost never shows up in a status page: the feed is up (HTTP 200) but wrong.
