What I focus on is not "do I know this technology", but rather:
About
Hi, I'm 武子康 (Zikang Wu).
A practitioner programmer focused on Java backend development, platform R&D, microservices architecture, data pipelines, and engineering infrastructure. Over the years, I've been deeply involved in designing, developing, optimizing, and delivering complex business systems, while continuously expanding my expertise into AI applications, multimodal interaction, and real-time voice pipelines.
What I Care About
- Can a system actually run in production?
- Can a solution stably deliver in real environments?
- Can a complex problem be broken down, refactored, and continuously optimized?
- Has the technology translated into actual value?
What I Do
My core background is Java backend and platform R&D. I work extensively with Spring Boot / Spring Cloud Alibaba stack, with experience in:
Microservices Architecture & Service GovernanceAPI Gateway, Authentication, Tracing, Rate Limiting & Circuit BreakerMySQL, Redis, Elasticsearch, Kafka, RabbitMQDevOps, CI/CD, Docker, Kubernetes, Rancher foundational Components, Common Scaffolds, Engineering InfrastructurePython / Go for Auxiliary Development & Automation ToolsAI Integration, Multimodal Pipelines, Voice Interaction & Real-time Communication
In recent years, I've participated in building systems from scratch and done architecture refactoring, performance optimization, and platform evolution from 1 to N. Rather than just writing business APIs, I prefer tackling problems that are "complex, messy, long-chain, and require real-world delivery".

Why I Write This Blog
This blog is not about churning out content or copying what others have written.
It's more like a long-term experimental field to record real problems and solutions in technical practice, my understanding of backend and AI application delivery, experiences with hardware and automation, as well as thoughts on running, growth, and long-term thinking.
What I aim to achieve with this content:
- Authentic: Write what I've truly done, stumbled upon, and thought about
- Clear: Explain complex problems clearly, no empty words
- Practical: Not just concepts, but things people can use and build upon
What I'll Post Here
- Java / Spring / Microservices / Middleware Practice
- Elasticsearch, Kafka, Redis, MySQL Engineering Issues
- Kubernetes, Docker, CI/CD, Release Process Optimization
- AI Agents, Multimodal, Voice Pipelines, Real-time Interaction
- Toolchains, Automation, Indie Developer Content
- Personal Projects, Experiment Notes, Milestone Summaries
If you're interested in these topics, there's probably something useful here.
What I Believe
- Don't believe in concepts, verify them
- Don't avoid complex problems, break them down first
- Don't just pursue 'knowing', pursue 'doing'
- Keep recording, keep iterating, keep growing
Technology for me is not just a work tool, but a way to understand the world, transform problems, and amplify personal capabilities.
About Me
Outside of work, I also continuously record life and thoughts. I love running, technology, and experimenting with new tools. I also like turning scattered experiences into written records. Compared to "hype", I care more about long-term accumulation; compared to "showing off", I care more about real growth.
This site itself is part of my long-term accumulation.

This site records technology, and also growth.
I hope that years from now, what's left here is not just articles, but also the trail of someone continuously moving forward.
