Seymen Parke Management Platform is a production ERP-style business application used by approximately 50 employees for daily operational workflows.
This repository presents a high-level case study of my frontend work on the platform. The production source code is private and is not included.
The screenshots in this repository have been anonymized. Customer details, business identifiers, financial figures, document numbers, and other sensitive data have been obscured.
A reporting interface that brings credit, payment, balance, installment, and bank-based data together through KPI cards, charts, and summary tables.
A financial operations screen for tracking card transactions, collections, bank activity, references, and related records.
A multi-section order workflow combining customer information, balances, delivery details, stock selection, line items, discounts, and calculated totals.
An invoice workflow that connects customer data, document details, source orders, stock balances, tax calculations, and shipment completion.
A data-heavy planning interface with filtering, searching, pagination, configurable columns, and operational actions for large inventory datasets.
Frontend Engineer
I designed and developed the UI/UX and responsive frontend of the platform from scratch while collaborating with a backend developer responsible for the API and server-side systems.
My responsibilities included:
- UI/UX design and interface planning
- Responsive frontend development
- API integration and frontend data flows
- Complex forms and multi-step business workflows
- Data tables, filters, sorting, and pagination
- KPI cards, charts, and reporting interfaces
- Document-oriented screens and printable outputs
- Performance improvements
- Maintenance, debugging, and production support
The platform supports business processes such as:
- Order management
- Invoice workflows
- Inventory and stock operations
- Material requirements planning
- Cash, card, and collection operations
- Finance-related processes
- KPI dashboards and reporting
- Document and output workflows
- Internal management operations
The platform contains large operational datasets that require search, filtering, sorting, pagination, configurable columns, and clear action patterns without overwhelming users.
Order and invoice screens combine customer information, balances, dates, warehouse data, stock selection, discounts, line items, totals, and validation in structured workflows.
Financial and operational data is presented through KPI cards, charts, summary tables, and pivot-style reporting interfaces designed for daily decision-making.
The application has been actively used in production for approximately three years. During this period, I worked on new requirements, bug investigation, usability improvements, performance work, and production support based on real user feedback.

I worked closely with the backend developer to align API contracts, business rules, and frontend requirements. My ownership was focused on UI/UX, frontend implementation, responsive behavior, API consumption, and production-facing user experience.
The production repositories are private because the platform was developed for a client.
This repository contains:
- No production source code
- No credentials or internal API details
- No customer records
- No private business documents
- No unmodified production data
The screenshots are included only to demonstrate interface complexity, workflow design, and frontend responsibilities.
