Building practical systems from real operational problems

OPERATIONS × PRODUCT × TECHNOLOGY

I turn messy workflows into clear digital systems.

I’m Gerald, a hands-on systems builder with experience across warehouse operations, production, inventory, IT support, ecommerce, and AI-assisted product development. I design around the people who actually have to use the system.

01 / ABOUT

Not software for software’s sake.

I build from operational friction: duplicated data entry, inventory uncertainty, confusing customer flows, production constraints, permissions that do not match the job, and interfaces that slow people down. My advantage is understanding both the physical workflow and the digital one.

BACKGROUND

Automotive glass distribution, graphics production, manufacturing, data entry, IT support, fulfillment, barcode/location tracking, and workflow improvement.

CURRENT DIRECTION

Building and refining operational software, ecommerce experiences, and production-aware tools using GitHub-first workflows, Cloudflare deployment, Supabase backends, and modern web stacks.

EDUCATION

Advanced Diploma in IT & Cyber Security, combined with years of hands-on production and warehouse experience.

02 / SELECTED WORK

Systems shaped by the floor, not the whiteboard.

Three projects that show how I work across operations, product direction, UX, system logic, testing, and iteration.

GLASS FLOW ERP / DASHBOARD
01ERP / WMS / OPERATIONSPROTOTYPE

Glass Flow ERP

A warehouse workflow system concept born from real problems in automotive glass distribution.

Problem

Spreadsheet and email handoffs, manual receiving, unreliable scanning, duplicate counts, unclear storage locations, pick-sheet mistakes, and delayed reporting.

My work

Mapped receiving → put-away → inventory → orders → picking → packing → delivery; designed barcode/location logic, role-based access, audit history, reports, permissions, and workflow safeguards.

  • Inventory & locations
  • Barcode workflows
  • Pick sheets
  • Roles & permissions
  • Audit logging
  • Multi-tenant concepts

GDP Clothing

A custom apparel platform combining streetwear branding with practical commerce and admin workflows.

I’ve directed and refined the storefront, product architecture, admin workflows, variant logic, media assignment, pricing controls, responsive behavior, and customer-facing trust details. The project is built around a real production workflow—not a generic shop template.

Custom Studio & DTF Flow

A production-aware customization experience where customers can choose garments, upload artwork, size and position it, and preview the result before ordering.

The workflow includes front/back print areas, measurement guides, artwork reset/delete behavior, garment matching, design intensity guidance, DTF film ordering, pricing logic, and advanced nesting concepts for efficient film usage.

HOW I WORK

Observe → map → simplify → build → test → refine.

01Start with the real workflow

What people actually do, where they wait, re-enter data, make mistakes, or lose visibility.

02Translate it into system logic

States, roles, permissions, validations, data relationships, exceptions, and handoffs.

03Refine against real use

Record the workflow, spot regressions, remove friction, and keep improving without breaking the parts that already work.

03 / CAPABILITIES

I work at the intersection of operations and digital product.

That means I care as much about data integrity, production constraints, roles, and exception handling as I do about how the interface looks.

01

Workflow & system design

Receiving, inventory, fulfillment, production, delivery, admin, roles, approvals, auditability.

02

Product & UX direction

Responsive interfaces, state clarity, navigation, forms, previews, filters, safeguards, customer guidance.

03

Ecommerce operations

Products, variants, custom ordering, production pricing, artwork handling, backend controls.

04

QA & iterative refinement

Video-based bug review, regression hunting, cross-flow consistency, edge cases, production readiness.

04 / EXPERIENCE

Built on hands-on work.

The portfolio is technical, but the foundation is operational: receiving, picking, production, installation, delivery, troubleshooting, and accuracy under real constraints.

ARG / Automotive Replacement Glass

Warehouse Associate / Delivery Driver

Receiving, storing, picking, delivery, inventory accuracy, product locations, and identifying workflow improvement opportunities.

Cowan Graphics Inc.

Installer / Production Worker

Installed vinyl, wallpaper, and fabric coverings; operated production equipment; worked to quality, safety, and deadline requirements.

Riteway Manufacturing

Sandblaster / Assembly

Industrial production, material handling, surface preparation, assembly support, and safe work practices.

DLH Lending Inc.

Data Entry / IT Support

Database accuracy, end-user troubleshooting, hardware/software setup, and basic network support.

SYSTEM DETAIL / GLASS FLOW

The details matter.

Useful operational software has to handle the boring-but-critical pieces: print flows, stock thresholds, permissions, security, role assignment, and the moments where one wrong click can cause a downstream problem.

Have a messy workflow worth fixing?

I’m interested in practical software, ecommerce, warehouse systems, production tooling, and operations-focused product work.
