Show and tell
A visual record of the systems, boards, models, interfaces, trials, and public-facing work behind the résumé—grounded in project records and source material.
Managed portfolio
Approved and awarded programme value only. The composition below is non-overlapping; pending applications and separate recognition are excluded.
Featured project · PSTS
Led a public-sector trial from production planning through field operations, validation, recovery, and close-out. The programme joined hardware manufacture, human-subject logistics, calibration, cloud data operations, budget control, and public-sector reporting in one delivery plan.
March–November 2024 · Project coordinator and CEO · Trial partner: The Chinese University of Hong Kong
Delivery against plan
Validated close-out
Public-safe summary from the signed completion report, technical presentation, and trial-user evaluation. Internal identifiers and participant records are intentionally omitted.
Original project assets
Each photograph and chart below was extracted from its original presentation object. Two device-screen close-ups and volunteer-facing images remain private because they contain unit identifiers or identifiable participants.
Source: original objects extracted from the public-safe pages of the PSTS project close-out presentation.
Programme management
The management load extended well beyond grant administration: physical production, people, protocols, data infrastructure, recovery planning, and formal close-out all had to stay synchronized.
Coordinated molds, tooling, procurement, assembly, small-batch production, and in-house quality checks for 100 devices.
Planned staffing, onboarding for 50 volunteers, device distribution, scheduling, operating instructions, and trial-site logistics.
Managed MEMS gas-chamber calibration, concentration-curve work, and GC–MS comparison as validation gates.
Ran device, app, gateway, and cloud workflows with data-quality monitoring and a local fallback path.
Replanned the schedule after benchmark-equipment downtime and resolved network saturation affecting uploads.
Coordinated budget control, audit support, completion reporting, user evaluation, and OEM follow-up.
Management under pressure
SignalCloud uploads initially reached about 80%.
DecisionAdded local storage fallback and revised the gateway and access-point topology.
ResultUpload reliability moved toward near-complete capture without blocking trial throughput.
SignalSensors needed roughly three minutes to stabilise.
DecisionIntroduced preheating, practice runs, and clearer onboarding guidance.
ResultReduced waiting friction while preserving the measurement protocol.
SignalBenchmarking equipment required repair and recovery.
DecisionSecured a three-month extension and resequenced validation and reporting work.
ResultCompleted the full benchmark and close-out package within the revised period.
Engineering artifacts
Working artifacts from the design archive, shown as public-safe renders. The authenticated source projects stay private; the visible evidence does not.
The assembled-board view connects the product story to the actual electronics: dual headers, sensor and pump interfaces, local storage, USB, controls, and power-management circuitry on a custom PCB.
Public-safe render captured from the owner-authorized EasyEDA project archive.
The routed-board view shows the dense integration work beneath the enclosure: signal paths, component placement, connector access, power sections, and the physical constraints of an instrument controller.
Public-safe capture from the owner-authorized EasyEDA design workspace.
The thesis figure makes the sensing sequence concrete: a pump selects headspace vapour or ambient air through a solenoid valve, drives it across the heated separation column, and presents separated compounds to the modular sensing electronics.
Figure 3.2, rendered from the owner-authorized Overleaf thesis PDF.
A working spatial model for the thesis gas-sensing setup brings the experimental system into one view: gas source, flow-control hardware, bench power, and the acquisition computer used around the sensing workflow.

Interfaces
Screens captured from running or published project interfaces—not decorative mockups.
