Client delivery, technical projects and business investigations. Each record sets out the situation, my contribution and what came of it.
Client engagement
Physical service work in Taiwan, connected to an overseas team through clear communication and remote engineering guidance.
Two paid engagements completed; a 5/5 review on the screen-replacement job.
Contract role · Lenovo ISG
Hands-on server qualification, issue documentation and follow-up across engineering teams and operating-system vendors.
Reviewable validation records, defect handoffs and visible next actions.
Business investigation
An investigation into whether recurring server qualification problems could support an independent service.
Stopped V1 when the evidence did not justify continuing the service concept.
Independent technical projects
Tracing data-transfer failures across hardware and software, then checking that the corrected system behaves as expected.
Stable 1 Gbps Ethernet reception; sustained PCIe DMA above 800 MB/s in the recorded setup.
Independent software projects
Python research workflows and C++ performance work built around reproducible experiments and comparable results.
A recorded SpMV improvement from about 0.28 to 1.3 GFLOP/s; modular research workflows.
Working sample
A reusable record for the intended outcome, current state, evidence, open items and next owner.
An editable Markdown template, ready to adapt to a bounded piece of work.
Closed investigations stay in the record. “Recorded work” identifies project results without implying current development activity. Dates are shown where established.
