Portfolio & Past Works
Works
Enterprise manufacturing systems, full-stack web platforms, and ERP-integrated digital products I have architected and engineered.
Automotive Part Costing & Pricing Engine
Manufacturing Cost Calculation & Sales Pricing System
Architected and delivered an enterprise-grade cost calculation system from requirements gathering to production rollout. Aggregates multi-departmental data (raw materials, machine hours, labor, tooling overheads) to compute real-time production unit costs and commercial sales quotations.
Key Focus Areas
- Cross-department Data Aggregation
- Automated BOM & Pricing Engine
- Profit Margin & Variance Modeling
- End-to-End System Architecture
Warehouse Location & SAP ECC6 Inventory System
Pallet Location Tracking & Automated ERP Stock Deduction
Engineered an intelligent warehouse spatial management platform tracking physical storage locations of parts and finished goods. Integrates directly with SAP ECC6 for automated inventory deduction, stock reconciliation, and location optimization upon dispatch.
Key Focus Areas
- Physical Bin & Pallet Mapping
- SAP ECC6 Automated Stock Deduction
- Real-time Inventory Reconciliation
- End-to-End Requirements to Rollout
Machine PM & Maintenance Tracking System
Preventive Maintenance & Breakdown Ticketing Platform
Built a centralized machine maintenance and breakdown dispatch system for the Preventive Maintenance (PM) department. Enables factory technicians to log machine alerts, assign technicians, track repair cycles, and maintain equipment history to minimize shop-floor downtime.
Key Focus Areas
- Real-time Breakdown Ticketing
- Preventive Maintenance Scheduling
- MTBF / MTTR Metric Analytics
- Shop-Floor Mobile-Responsive UI
Automated Part Weight Inspection & QA System
Auto-Scale Hardware Integration & Compliance Logging
Developed an automated quality inspection platform interfacing directly with digital weighing hardware. Automatically captures component weights, evaluates compliance against engineering tolerances, records inspection logs, and generates quality control certificates on the factory floor.
Key Focus Areas
- Direct Auto-Scale Hardware Link
- Tolerance Validation (Pass/Fail)
- Audit Log & Certificate Generation
- Shop-Floor Operator Interface

Currently Exploring
Skills & Exploring
Not just building software —
learning how technology fits into real manufacturing.
ERP Integration & Operational Flow
Understanding how data moves across the factory. Currently studying ERP system architecture and data flow between production, inventory, and planning to build software that aligns with real-world operations rather than just being functional.
RPA & Process Automation
Reducing repetitive human tasks through automation. Designing workflow automation to minimize manual tasks such as data entry, report generation, and system synchronization.
AI Automation in Manufacturing
Exploring practical AI for real production environments. Focusing on AI that provides decision support and shop-floor data analytics, rather than purely experimental AI concepts.
Image Processing for Quality Inspection
Teaching machines to see what humans might miss. Developing computer vision systems for product inspection to improve accuracy, eliminate human error, and establish reliable quality standards.
“ I’m not chasing trends —
I’m learning technologies that solve problems where they actually happen. ”
