Side Projects

Teleguard

An LLM-powered ad-blocking bot for Telegram groups, written in Rust with teloxide and running in production (@TeleguardAdBot).

Three-tier verdict pipeline — exact Redis cache → pgvector semantic cache (BGE-M3) → LLM — with single-flight collapsing concurrent requests, sharply cutting LLM calls and latency.
Ordered provider chain with failover across Anthropic, OpenAI, and local compatible endpoints, tracked by latency and success rate.
False-positive feedback loop: one admin tap restores the user and feeds the sample back as a few-shot example, so verdicts keep self-correcting.
Admin console embedded into the single binary at compile time via rust-embed — no extra deployment artifacts.

SmsLLM

An iOS scam-SMS filter shipped on the App Store, built with a Rust + Axum backend, SwiftUI, and an ILMessageFilterExtension.

Designed an offline-classification architecture with out-of-band rule updates around Apple's sandbox (the extension cannot reach the network), so editing rules takes effect immediately without an App Store release.
A signal-weighted scoring engine replaces keyword matching, with an OTP/2FA fast-path guard that sharply reduces false positives.
The engine is language-agnostic behind a language-pack abstraction, shipping Chinese and English out of the box; a new language is one more pack.
Moved the LLM off the delivery path into offline rule training: reported samples → candidate rules → human review → client re-sync.

MedVault

A family medicine-cabinet manager on the App Store, with a Rust/Axum backend, a SwiftUI iOS app, and a Taro WeChat mini-program.

The AI assistant runs a tool-calling loop where writes never execute server-side: they are emitted as SSE events for the client to confirm and send through the normal endpoints, so there is no privileged AI write path.
Chat streams over SSE, routing image turns to a vision model and tool turns to a text model, with an iteration cap guarding against runaway loops.
Authorization is cabinet-scoped rather than user-scoped, returning 404 instead of 403 for non-members to avoid leaking resource existence.
One backend API serves both iOS and the WeChat mini-program; StoreKit subscriptions integrate the App Store Server API to self-heal lost webhooks.

Open Source Projects

TortoiseORM

One of the most popular asyncio ORMs in Python, with a Django-like API. I contributed features such as F-expressions, signals, and GROUP BY support, and now serve as a maintainer.

FastAPI-Admin

An out-of-the-box admin dashboard for the FastAPI + TortoiseORM stack, inspired by Django Admin and communicating over REST. The project now lives in its own GitHub organization.

fastapi-cache

A decorator-based cache for FastAPI endpoints and function results, supporting Redis, Memcached, DynamoDB, and in-memory backends plus HTTP cache semantics such as ETag and Cache-Control.

Aerich

A database migration tool I built for TortoiseORM, comparable to Alembic for SQLAlchemy. Developed independently and now the official migration solution under the Tortoise organization.

asyncmy

A high-performance asyncio MySQL/MariaDB driver with a Cython-powered protocol core, an aiomysql-compatible API, a built-in connection pool, and binlog replication support.

meilisync

Real-time sync from MySQL, PostgreSQL, and MongoDB to Meilisearch with both full and incremental modes, paired with the meilisync-admin dashboard.
