Hello, I'm Justin. I am a
Full Stack
Engineer.
Full-stack engineer building reliable systems for complex workflows.
Some things I've built
Sierra Instruments Configurator
Designed and built an internal configurator that automates complex product configuration, pricing, and quote generation for a manufacturing environment. The system replaces a manual, error-prone process by enforcing business rules server-side, generating deterministic configurations, and integrating directly with HubSpot for lead generation and Epicor ERP for BOM creation, materials rollups, and order readiness.
I owned the system end-to-end, including data modeling, backend APIs, frontend workflows, validation, and integration logic, with a focus on correctness, maintainability, and evolving business requirements.
What it Demonstrates
- Rules-driven system design with server-side enforcement
- ERP and CRM integration with deterministic outputs
- Data modeling for correctness, traceability, and evolution
- API design that enforces business invariants
- End-to-end ownership of a business-critical internal system
- Replacing manual workflows with reliable automation
Sierra Instruments Service Portal and RMA Automation Platform
Designed and built a customer-facing service portal that manages the full RMA lifecycle, from request intake through ERP-backed fulfillment.
The system integrates directly with Epicor ERP to create RMAs and sales orders, replacing manual, multi-step processes with a largely automated workflow.
This significantly reduced turnaround time and consolidated operational workload from multiple staff members to a single overseer role.
Engineer Change Request Portal
Designed and built an internal portal to manage the full lifecycle of engineering change requests, from submission through review and disposition. The system integrates with Microsoft SSO for secure authentication and role-based access, provides employees with dashboards to submit and track their requests, and enables engineering administrators to review, approve or deny changes, and assign follow-up actions to specific owners. The platform replaces ad-hoc change coordination with a structured, auditable workflow focused on accountability and traceability.
Content Scheduler
Content scheduler is a SaaS application that empowers users to easily design and schedule updates for their website.
With a user-friendly interface and intuitive design, it is a great choice for small businesses looking to streamline their website management process.
Content Scheduler is available on the Wix App Market for easy access and integration with Wix websites.
