Connor Illingworth — Full-Stack Engineer

Summary

I take manual, error-prone business processes and turn them into production systems: web apps, APIs, device apps, and ERP integrations. Most recently I replaced an emailed-Excel ordering workflow with a Next.js customer portal on a NetSuite SuiteScript backend — 3,500+ orders and $6.5M+ in order volume in its first six months.

I work across the stack — TypeScript, Next.js, React, C#/.NET, SQL, Azure, Docker, GitHub Actions — plus platform work in NetSuite SuiteScript and SDF, and native apps for iPad and Apple TV. As lead developer I own the full lifecycle: data modeling, API design, deployment, and the system once it is in production.

Before that: an iPad-based electronic batch-record system that replaced paper manufacturing records at a nutraceutical producer, plus the check-in kiosks, warehouse status displays, and Azure-hosted dashboards its operations teams work from.

Featured Project

Customer Ordering Portal for NetSuite

Replaced an emailed Excel order-form workflow with a production customer portal integrated with NetSuite.

Problem

Customers submitted orders through emailed Excel forms, which account managers manually reviewed and entered into NetSuite. The process created extra administrative work, slower order handling, and more opportunities for data-entry mistakes.

Solution

Built a Next.js prototype that recreated the order workflow as a web application, connected it to a NetSuite SuiteScript backend, and used the prototype to get stakeholder approval. After approval, developed the prototype into a fully usable customer portal.

Result

The portal replaced the emailed Excel order-form process. Customers now manage their orders directly through the web application, and order data flows into NetSuite without manual account-manager entry — eliminating an estimated 314 hours of administrative work in the first six months.

Role

Full-stack developer responsible for prototyping, front-end development, NetSuite SuiteScript backend work, and turning the approved prototype into a production business application.

Additional Operational Systems

Alongside the customer ordering portal, I built internal tools and display systems to improve visibility across customer pickup and warehouse workflows.

Customer check-in kiosks

Front-lobby kiosks that allow pickup customers to check in on arrival.

Warehouse order displays

TV displays showing current warehouse order status, upcoming orders, and orders falling behind schedule.

Operational dashboards

Azure-hosted display tools designed for real-time visibility into customer service, warehouse, and fulfillment workflows.
