PrintQuoteNow

A comprehensive print management platform featuring an advanced gang-run optimization algorithm, instant quoting, production workflows, and accounting integration through QuickBooks. The platform replaced the client’s legacy quoting system, which had become expensive, outdated, and difficult to maintain, giving the business full control over their quoting infrastructure and long-term evolution.

Project Overview

Understanding the Project

The Goal

Build a scalable print management system capable of generating instant, highly optimized print quotes while managing the full production lifecycle, invoicing, and reporting; while enabling the client to replace an expensive, outdated legacy quoting system with a modern in-house platform.

The Challenge

Designing and implementing a complex gang-run algorithm to optimally position multiple print jobs on a single sheet, minimizing paper waste and machine time, while keeping the system flexible for continuous feature expansion over multiple years.

My Role

Lead Full-Stack Developer responsible for system architecture, core algorithm development, API design, cloud infrastructure, and long-term platform evolution, including the migration away from a costly legacy quoting solution.

What I Built

  • Gang-run optimization algorithm to efficiently position multiple print jobs on a single sheet.
  • Instant quote engine calculating costs based on paper usage, machine time, ink, and finishing processes.
  • REST API to support quoting, production workflows, and integrations.
  • Invoice management module with QuickBooks API integration to push invoices and synchronize accounting data.
  • Reporting system capable of exporting synchronized financial and production data.
  • AWS cloud infrastructure setup and deployment for scalability and reliability.

Architecture Design Decisions

These decisions were intentional to ensure the site feels professional, calm, and easy to navigate:

  • Custom gang-run algorithm developed from scratch using mathematical and geometric optimization techniques
  • Modular system design to allow continuous feature expansion without disrupting existing workflows
  • Separation of pricing logic, production logic, and accounting integrations for maintainability
  • Use of AWS managed services to ensure scalability, fault tolerance, and long-term reliability

Results & Learnings

The platform enabled printing companies to generate instant, highly optimized quotes and fully replace a costly, outdated legacy quoting system. This reduced dependency on third-party software, improved maintainability and long-term scalability, and streamlined quoting, invoicing, and reporting workflows through QuickBooks integration.
