I build Java infrastructure, developer tools, and runtime systems — from language runtimes and query engines to network gateways and high-performance data processing.

I focus on building infrastructure that makes complex engineering tasks simpler, faster, and easier to integrate.

Core methodology: declarative configuration-driven development — you just "declare" what you want using XML or annotations, and the jquick toolchain automatically handles the rest of the complex execution logic.

End-to-end infrastructure coverage: from data collection (jquick-curl / jquick-connector), processing and aggregation (jquick-transform-function / jquick-java), persistence to database (jquick-datasource / jquick-mybatis), to final visualization (jquick-pdf / jquick-bi) — the entire process is seamlessly connected. Among them, jquick-sql serves as a distributed federated virtual data warehouse engine, providing a unified query entry for heterogeneous data sources at the upper layer and shielding underlying differences.

I believe in "less is more": each tool solves exactly one problem, and solves it cleanly and thoroughly.

📦 All projects follow: lightweight dependencies, low intrusion, out-of-the-box

Note: Projects marked with ✅ in the "XML Configuration Support" column refer to support for declarative XML configuration files similar to MyBatis Mapper.xml or jquick-excel.xml (i.e., defining mapping rules, styles, transformation logic, SQL bindings, and other business configurations via XML), rather than merely having basic XML parsing capabilities.

Project	Description	Primary Use	XML Support?	Stars	Included in Awesome Java?
jquick-hub	jquick-hub (TCP Gateway) Available as a Docker image: docker pull paohaijiao/jquick-hub:latest	A high-performance protocol-sniffing TCP gateway built on Netty 4. It exposes a single public port and automatically routes inbound data package to different backends based on the first packet	❌		No
jquick-json	using JQuick-ASM bytecode to generate alternative reflections, achieving a performance improvement of up to 54 times for JSON serialization/deserialization.	JQuick JSON is a bytecode-driven JSON serialization and deserialization library for Java. It leverages ASM to generate optimized object mapping code at runtime, reducing the overhead associated with reflection-based serialization.	❌		No
jquick-curl	Lightweight HTTP client — as concise as cURL, with uncompromising performance	Curl as code, replacement for OkHttp/Apache HttpClient	✅		Yes
jquick-connector	Universal data connector — converts any tool/data source into a unified in-memory data interface	Unified access to heterogeneous data sources, multi-source data adaptation	✅		No
jquick-excel	Zero-config Excel read/write tool — say goodbye to POI boilerplate, import/export in one line	High-performance Excel processing with streaming, style caching, AST caching, and shared OPCPackage parsing.	✅		Yes
jquick-path	JSON Path query tool — concise syntax to quickly extract JSON data, like XPath for XML	Quickly extract values at specified paths from nested JSON	❌		No
jquick-transform-function	Universal data function library — provides 200+ out-of-the-box data processing methods	SPI-based function registry with support for dynamic extension	✅		No
jquick-java	Dynamic business scripting language — combines Java's strong logic with XML declarative configuration	Dynamic business rule orchestration such as credit rating, risk scoring	✅		Yes
jquick-pdf	Native Java PDF generation tool — no browser/WebKit dependency, built-in 30+ ECharts like chart types	Server-side PDF report generation without a browser	❌		Yes
jquick-mybatis	Lightweight MyBatis enhancement framework — zero redundant annotations, zero business code intrusion	Simplifies MyBatis single-table CRUD, dynamic conditions, pagination, and multi-table associations	✅		No
jquick-datasource	Universal data source management — supports automatic DDL/DML generation	Dynamically generate table creation / CRUD SQL, simplifying data source operations	❌		No
jquick-sql	Distributed federated logical data warehouse query SQL engine	Cross-database / cross-heterogeneous data source SQL federated analysis	✅		Yes
jquick-bi	Jquick-bi engine (Vue)	Online BI analytical processing (in development)	✅		No

Simple, reliable, practical.
The purpose of tools is to let developers forget about the tools themselves and focus on the real business logic.

I don't chase flashy tech. I pursue this — when you next face those "have-to-do-but-don't-want-to-spend-time-on" tasks like Excel, HTTP, or SQL, you'll remember "there's a tool that can handle it", and wrap it up within 5 minutes.
