I'm a software engineer focused on B2B commerce systems, backend platforms, and AI-powered internal tools.

Currently, I work on real-world B2B and cross-border commerce scenarios, including product data, seller validation, order workflows, compliance checks, and operational automation.

I'm especially interested in building tools that turn messy business workflows into reliable, automated systems.

• Building AI-assisted tools for B2B operations
• Learning and practicing full-stack development with TypeScript
• Exploring AI Agent, tool calling, RAG, and workflow automation
• Turning real business pain points into practical software products
• ⚽ Building AI-powered football analytics tools
• Preparing for remote-friendly engineering opportunities

Backend Engineering  -> Java / Spring Boot / MyBatis / MySQL / Redis / MQ
Full-stack           -> TypeScript / React / Next.js / Hono / Nest.js
AI Engineering       -> AI Agent / RAG / Tool Calling / Workflow Automation
Business Domain      -> B2B / Cross-border Commerce / 3PL / Operations Tools

I currently work as a software engineer at GigaCloud, focusing on backend engineering for B2B commerce platform systems.

My work involves building and maintaining backend services that support cross-border business workflows, product and seller operations, data validation, and internal operational tools.

My daily work includes:

Building backend APIs for internal B2B platform systems Implementing business validation rules and operational workflows Supporting product, seller, and cross-border commerce scenarios Handling batch data processing and import/export features Working with relational databases and SQL optimization Collaborating with product, QA, and business teams to deliver reliable features

Tech stack:

Java / Spring Boot / MyBatis-Plus MySQL / OceanBase / Redis / RabbitMQ / XXL-JOB Git / CI workflows

This experience helps me understand how real B2B platforms operate, and it inspires me to build AI-powered tools for business workflow automation, data validation, and operational efficiency.

I believe software engineers should not only write code, but also understand business problems deeply.

My long-term goal is to become a full-stack product engineer who can independently discover pain points, design systems, build products, and deliver real business value.

I care about:

• Practical engineering
• Clean system design
• Business-oriented problem solving
• AI-native product workflows
• Remote collaboration
• Building in public

• React and modern frontend development
• Next.js full-stack application architecture
• Hono / Nest.js backend development
• AI Agent design patterns
• B2B SaaS product thinking
• English communication for global engineering teams

Languages:    Java, TypeScript, JavaScript, SQL
Backend:      Spring Boot, MyBatis, Hono, Nest.js
Frontend:     React, Next.js, Tailwind CSS
Database:     MySQL, PostgreSQL, OceanBase, Redis
AI:           RAG, Tool Calling, AI Agent, LLM APIs
Tools:        Git, Docker, Linux, GitHub Actions

• Build and launch 2–3 practical AI-powered B2B tools
• Improve English communication for remote work
• Contribute to open-source projects
• Write more technical articles
• Build a strong public portfolio around AI, B2B, and full-stack engineering
