Hands-on experience across physical and digital systems.
LPSD ENGINES / CAT POWER MODULES
Real power.
Real assembly.
I assembled large LPSD engines and propane- and natural-gas Cat Generator Power Modules, working from blueprints and wiring diagrams through assembly and quality checks.

HOSHIZAKI / COMMERCIAL REFRIGERATION
Build. Diagnose.
Repair.
At Hoshizaki, I built upright commercial refrigerators and coordinated production, then led diagnosis and repair for global field-unit returns. The work connected assembly, fault diagnosis and production improvement.

Get closer.
It’s all connected.
A detail matters because of what it connects to. Across manufacturing, repair, operations and software, I follow the problem through and keep the next person in mind.

I built software, games, apps and websites for years before AI-assisted development. Today, AI helps me extend that established practice.

05 / INDEPENDENT DEVELOPMENTA PRACTICE THAT PREDATES AI
BUILDING SINCE 2010
The tools evolved.
The builder
was already here.
Software. Games.
Apps. Websites.
Then AI accelerated it.
Since 2010, my independent practice has spanned software development, prototyping, user experience, brand identity and automation, alongside my work with physical systems.
AI now helps me explore, implement and iterate faster. I remain responsible for the product decisions, architecture, testing and follow-through.

Hiring infrastructure.
Built from the work up.
I designed, built and operated a hiring and career platform spanning AI, software engineering, electrical, mechanical, plumbing and other skilled trades. It began with data center hiring and expanded across these fields. My work covered candidate and employer experiences, data pipelines, AI workflows, permissions and operating tools.

THE PRODUCT PROBLEMA title is only
A title is only
the beginning.
Technical hiring depends on the work beneath the title: systems, skills, certifications, location and experience. I built a shared evidence model that connected job discovery to matching, career tools and hiring decisions.
The candidate workspace connected profiles, saved jobs, résumé tools and application tracking. The employer side covered postings, applicant review, interviews, offers and onboarding.

Source adapters converged on one validation contract. Raw payloads remained separate from canonical fields, so improving a normalizer did not erase the original evidence.
Keyword rotation used persisted state, source locks and actual inserted counts. High-yield terms received bounded priority while exploration protected coverage.

MODEL THE WORKMatch evidence.
Match evidence.
Preserve distinctions.
The taxonomy mapped inconsistent employer vocabulary while protecting roles that should remain separate. Explicit, extracted and inferred signals carried different evidence quality.
Matching combined role compatibility, required qualifications, skills, seniority, location and candidate preferences. Guardrails, fixtures and comparison checks supported consistent scoring across the product.
A 0–100 match score described fit within the platform’s rules. It was not a probability of getting hired.

The same discipline extended to cover letters, interview preparation, skills-gap analysis and enrichment: narrow model responsibilities, structured outputs and explicit retry or manual paths.
Permissions, usage limits, application states and persistence remained conventional software logic.

Build the controls
behind every action.
Employer workflows brought ownership, review states, billing and access rules. Operator tools exposed ingestion runs, source health, quarantine, recovery and audit history.
Application automation evolved through browser-based experiments. The final design shifted toward Manual Assist and External Handoff, retaining capability checks, immutable snapshots, idempotent runs and an event trail.
The case study records 462 passing tests at final verification. That is a historical project result, not a new audit of the archived service.
NINE MONTHS OF ENGINEERING

The architecture changed as real data and operating constraints exposed what needed to improve.
- NOV 2025
Connect the product. Candidate, employer and admin experiences; authentication and early AI workflows.
- JAN—APR 2026
Separate the domains. Feature boundaries, ingestion workers, billing and application automation.
- MAY—JUN 2026
Share the evidence. Career Studio, matching, taxonomy, learning, privacy and hiring workflows.
- JUL—AUG 2026
Improve the operating model. Enrichment, adaptive acquisition, telemetry and application transport redesign.

The public technical edition: 20 pages covering the product, architecture, data and operating decisions.
This account draws on the supplied Rack & Role: Product Engineering Case Study, public technical edition, covering November 2025–August 2026, and the preserved public interface captured September 12, 2026.
The case study reports 73,409 aggregate job rows, 69,640 active quality-cleared jobs and 13,827 distinct companies in its final aggregate snapshot. Companies represented in the data are not a customer count. Its mature taxonomy contains 108 canonical roles, 280 aliases and 1,646 anti-merge rules; its architecture inventory lists 212 tables/views and 93 Edge Function source units.
The public-interface capture shows a separate count of 69,599 roles. The case study does not reconcile that difference or give its aggregate snapshot an exact day, so the figures are kept separate here. Earlier lifetime ingestion totals are not combined with the final corpus.
Feature descriptions preserve implemented capabilities, experiments and the final design direction. Application automation is not presented as universally reliable. Product delivery and technical scale do not establish revenue, customer adoption or business success.
