Personal Technical Profile

Hi, I'm Zikang Wu.

Backend Engineering × AI Engineering × Indie Building

I am a practitioner programmer grounded in backend engineering, platform development, microservices architecture, data pipelines, and engineering infrastructure. I am now extending that foundation into AI Engineering, agents, real-time voice modules, indie tools, and automation systems, turning complex problems into runnable, reviewable, long-lived works.

About Zikang Wu page cover: backend engineering, AI Engineering, and indie building

Who I Am

I think of myself as a long-term builder: I write code, build systems, create tools, and keep records of the process. This website is not just a resume page. It is my public technical archive for articles, projects, experiments, and milestone reviews.

What I focus on is not "do I know this technology", but rather:

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:

Backend & Platform Engineering

Java / Spring Boot / Spring Cloud Alibaba
Microservice governance, gateway, auth, tracing
MySQL, Redis, Elasticsearch
Kafka, RabbitMQ, data pipelines
Docker, Kubernetes, Rancher, CI/CD

AI Engineering

LLM application engineering and model service integration
Agent / MCP / Function Calling
STT / LLM / TTS real-time pipelines
Trace / Observability / Runtime Config
Cost, latency, reliability, and evaluation governance

Indie Building

AscendLab and browser-side tools
AI Workflow previews and rule repositories
stop-slop-zh, code generators, automation scripts
Personal productivity systems and public work polish

Writing & Long-term Archive

Technical blog, project reviews, tutorial series
AI research notes, content governance, SEO / GEO
Annual reflections and digital-life experiments

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".

Current Projects

wzk.icu: personal technical portal and long-term content archive
AscendLab: indie tools and AI Workflow lab
AI Voice Module: edge-cloud AI interaction system
AI Infra Handbook: AI infrastructure learning and practice notes
stop-slop-zh: Chinese AI writing anti-slop rule project
Code Generator: engineering productivity for business development
TeslaMate Dashboard: digital-life experiment

Engineering Timeline

2019-2021

Java Backend & Business Systems

Built the foundation around Spring Boot, MySQL, Redis, API development, and business system delivery.

Cloud Native, Platformization & Automation

Focused on Kubernetes, DevOps, platform engineering, automation tools, and engineering efficiency.

2025-2026

AI Engineering, Indie Building & Long-term Works

Combining LLMs, Agent / MCP, real-time voice, indie tools, and backend engineering into systems that can run, be maintained, and accumulate over time.

Focus Areas

Backend & Platform Development

Microservices, API Gateway, Service Governance, Data Pipelines, Caching, Message Queues, System Stability, Performance Optimization, DevOps, Cloud Native

AI Engineering

LLM application engineering, agents, Function Calling / MCP, model serving, real-time voice pipelines, evaluation, and observability

Indie Tools & Products

Browser-side tools, AI workflows, rule sets, code generators, personal automation, and reusable small product experiments

Writing & Long-term Archive

Original engineering practice, tutorial series, project reviews, AI research, personal growth, and long-term public work systems

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 Write Here

Backend engineering, microservices, platform development, and system reliability
AI Engineering, LLM applications, Agent / MCP, and real-time voice pipelines
Indie tools, AI workflows, code generators, and automation practice
Personal websites, SEO / GEO, content governance, and long-term public work systems
AI research notes, project reviews, milestone summaries, and personal growth records

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, iterating, and recalibrating

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.
