Über Yihong
I am a software engineer based in Germany, specialising in automation, backend development, and AI-enabled workflows for business operations.
I help companies and teams reduce manual work and improve reliability by designing clean, pragmatic systems — from data processing and API-driven backends to AI-assisted automation and internal tools. My focus is always on solutions that are easy to operate, well-documented, and ready for real-world use rather than prototypes.
My technical background includes Python (FastAPI), JavaScript (Node.js, React), SQL/MySQL, and workflow automation using modern tooling. I frequently work on tasks such as data cleaning and enrichment, system integrations, process automation, and AI-assisted decision support.
I value clear communication, structured problem-solving, and realistic delivery timelines. Clients typically work with me when they need a reliable engineer who can quickly understand business requirements and turn them into maintainable technical solutions.
I am open to short- and mid-term projects, especially in automation, internal platforms, and AI-assisted business workflows.
