01 — Engineering
Medical-device instrumentation, process development, and failure diagnostics across two university labs and two manufacturers, 2023 to today.
Extracting individual diamond grains from Keyence VK-X110 laser-scan height maps of a grinding wheel: per-grain base-line detection, a solid-closure rule that adds no unmeasured surface, and STEP export of grain solids for contact simulation.
Built a browser review tool that adjusts each grain's base line, records accept/reject verdicts, and drives the CAD bake.
A wire-forming process that produces multi-radius TAVI (transcatheter aortic valve implantation) medical wires in a single draw, reducing manufacturing time.
First-author poster, PRESM 2025, Chiang Mai: Stretch Bending Springback Prediction in Thin Metal Wires.
Python supervisory control for the stretch-bending machine, synchronizing a Zaber linear stage with an Arduino load-cell channel for coordinated motion with force feedback and logging.
A cantilever test rig with laser displacement sensing that quantifies medical-wire tip stiffness at 0.05 N per gram of applied force.
A prototype achieving 80% radial compression of a 14 mm impeller for an expandable percutaneous ventricular assist device, using Nitinol shape-memory actuation by controlled heating.
Stress–strain analysis of compressibility and structural integrity.
A failure-diagnostics framework built from high-speed video of stopper–drug air-compression dynamics, enabling non-destructive detection of plunger-actuation failures and needle blockages.
Co-developed an extended-Bernoulli model predicting injection time across design and fluid parameters; characterized the injectability of microparticle formulations.
Extended wire-straightening capability from 0.2 mm to 0.1 mm diameter by maximizing plastic deformation through reduced curvature radii.
Designed a magnetic oil-filtration system and robotic-arm welding components in Inventor.

02 — Projects
Systems where a model does bounded work inside guardrails I designed, and the output is verified before it ships.
01 — Agent
An autonomous web agent that drives a live product and renders the walkthrough as a video.
Nemotron 3 Super 120B acts inside a NemoClaw sandbox under seccomp and network-policy guardrails. A sandboxed discovery pass logs actions that a host-side performer replays into the finished video — so untrusted page content never reaches the host.
A 12-target evaluation suite with independent grading raised task success from about 58% to about 92% and cut mean run time 46%. Selected by NVIDIA judges for “innovation and technical use of NemoClaw”; demoed at GTC Taipei and on NVIDIA's livestream.
02 — Product
Agentic launch-film producer.
It opens a live product page in a headless browser, diagnoses the conversion gap, plans and prices the cut, gates production behind a credit system, and renders a 1080p film from a curated scene library on a Railway worker, with automated delivery checks.
03 — Studio
Studio for technical explainer and product films.
Claude Code agent skills chain web research with programmatic Remotion (React/TypeScript) rendering. 10+ films shipped, three sold to paying clients.
04 — Client work
Seafood processor in Costa Rica.
A bilingual company website — Next.js, 248 static routes, structured data — live at delimarcr.com.
An AI retouching pipeline turned phone photos of packaged products into 25+ retail-grade 2K packshots now live on the product pages, with an exact-logo QA rule and an approval gate before publishing.
05 — Prototype
An iPhone prototype in SwiftUI and ARKit: on-device OCR of a printed free-convection problem, an isothermal-vertical-plate solution via Churchill–Chu correlations (Ra, Nu, h, q), and an AR flow model. The language model cannot invent boundary conditions.
06 — Prototype
A Python and CadQuery prototype: voxel-based irregular-part nesting with simulated annealing and stability constraints; FEFCO 0201 carton and foam-free insert die-lines; 144 tests.
