Hierarchia is a production AI-powered document review platform built for inspection and audit teams. It validates inspection reports against quality rules using AI in under 60 seconds, replacing 6-10 hours of manual review per manager per week.
CHALLENGE: Inspection teams were manually reading every submitted report, checking quality against dozens of rules. Reviews were inconsistent across managers, submissions arrived via WhatsApp/email with no audit trail, and deadlines were missed.
MY SOLUTION:
AI Validation Engine: Built an AI system that scores every inspection report against configurable quality rules in under 60 seconds. Managers see scores, summaries, and risk flags without reading a single page.
RAG-Based Smart AI Chat: Implemented a Retrieval-Augmented Generation chat system (pgvector) allowing managers to ask questions about any submission and get instant, context-aware answers.
17-Module Platform: Delivered Overview, Tasks, Submissions, Messages, Announcements, Materials, Smart AI, Reports, Activity Log, Validation Rules, Team Members, Departments, Access Control dashboard.
Full RBAC: Granular role-based access control for different team hierarchies.
TECH STACK: Next.js, Supabase, pgvector, RAG, AI Validation, RBAC
RESULTS: 82% AI pass rate on submissions. Average quality score 84.2. Saves each manager 6-10 hours/week. Live at showcase.system.zamdevai.com (http://showcase.system.zamdevai.com)

Developed a specialized e-commerce workflow automation system for a custom printing business, handling complex order parameters (size, material, artwork validation) that standard Shopify setups couldn't manage.
Key Engineering Contributions:
Automated File Validation: Built a pre-processing pipeline that automatically checks uploaded artwork for resolution (DPI) and dimensions before accepting the order, reducing print errors by 100%.
Dynamic Pricing Logic: Engineered a custom pricing algorithm that calculates costs in real-time based on square footage, material type, and bulk quantity breakpoints.
Order Routing API: Created a custom integration (SinaLite API) to automatically route specific line items to third-party wholesalers for fulfillment while keeping internal production items in-house.
Status Sync: Two-way sync between production floor status and customer-facing order tracking.
