Hardware systems and RF circuits
From RF and BMS work to system architecture, I turn hardware constraints into practical engineering decisions.

About
Turn difficult engineering work into useful tools.
Introduction
I have more than 15 years of hardware R&D experience, focused on RF circuits and system architecture, with growing work in AI automation and independent product experiments. JK Space is where I document practical engineering work, tools, and technical perspectives.
For example, the PCB test-point comparison tool turns the comparison of reports from two hardware revisions into a browser-based workflow for report parsing, test-point differences, and DXF coordinate alignment.
Expertise
AI automation workflows
I use n8n, Dify, and agent-based tools to connect data, workflows, and product prototypes.
Independent product experiments
I use rapid prototypes to validate needs and explore engineering tools and digital services that can improve over time.
How I work
- Clarify engineering constraints first, including report structure, data filtering, and coordinate-system boundaries.
- Connect the workflow with tools, using AI collaboration and automation to reduce repetition and produce actionable results.
- Validate needs with rapid prototypes grounded in real use cases, then keep refining the tool and product direction.
