Enterprise Procurement Platforms
End-to-end procurement system with vendor management, automated workflows, and real-time analytics.
Overview
This topic, showcases my expertise in designing and implementing end-to-end procurement systems. These platforms streamline vendor management, automate workflows, and provide real-time analytics to optimise procurement operations. By utilising technologies such as React, TypeScript, Node.js, and PostgreSQL, the solutions I have created are designed to enhance efficiency and scalability for all procurement processes.
Key Experiences
Vendor Management System
- Centralised dashboard for onboarding and evaluating vendors.
- Automated vendor scoring based on predefined metrics.
Automated Workflows
- Streamlined procurement processes, including purchase requests, approvals and order tracking.
- Customised workflows to provide adaptability for unique organisational needs.
Real-Time Analytics
- Created interactive dashboards for monitoring KPIs, spending patterns and vendor performance.
- Added drill-down capabilities for detailed insights.
Role-Based Access Control (RBAC)
- Implemented role-based permissions ensuring that sensitive data is accessible only to authorised users.
- Provided granular access control for specific reports and functionalities.
Sample Implementations
Vendor Management Module
The following is a simplified example demonstrating a Node.js API, which manages vendor onboarding and scoring:
import express from 'express';
import { Pool } from 'pg';
const app = express();
const pool = new Pool({
user: 'user',
host: 'localhost',
database: 'procurement',
password: 'password',
port: 5432,
});
app.use(express.json());
// API to add a new vendor
app.post('/vendors', async (req, res) => {
const { name, email, performanceScore } = req.body;
const query = 'INSERT INTO vendors (name, email, performance_score) VALUES ($1, $2, $3) RETURNING *';
const values = [name, email, performanceScore];
try {
const result = await pool.query(query, values);
res.status(201).json(result.rows[0]);
} catch (err) {
res.status(500).send(err.message);
}
});
app.listen(3000, () => {
console.log('Server running on port 3000');
});
Workflow Automation
This simplified React example shows an interface for purchase request approvals:
import React, { useState, useEffect } from 'react';
interface PurchaseRequest {
id: number;
description: string;
amount: number;
status: string;
}
const PurchaseRequests = () => {
const [requests, setRequests] = useState<PurchaseRequest[]>([]);
useEffect(() => {
fetch('/api/purchase-requests')
.then((res) => res.json())
.then((data) => setRequests(data));
}, []);
const approveRequest = (id: number) => {
fetch(`/api/purchase-requests/${id}/approve`, { method: 'POST' })
.then(() => {
setRequests(requests.map(req => req.id === id ? { ...req, status: 'Approved' } : req));
});
};
return (
<div>
<h1>Purchase Requests</h1>
<ul>
{requests.map((req) => (
<li key={req.id}>
{req.description} - ${req.amount} - {req.status}
{req.status === 'Pending' && (
<button onClick={() => approveRequest(req.id)}>Approve</button>
)}
</li>
))}
</ul>
</div>
);
};
export default PurchaseRequests;
Real-Time Analytics Dashboard
This simple example demonstrates a small section of an analytics dashboard, which is using D3.js for visualising procurement data:
import * as d3 from 'd3';
const data = [
{ category: 'Office Supplies', value: 5000 },
{ category: 'IT Equipment', value: 20000 },
{ category: 'Furniture', value: 10000 },
];
const svg = d3.select('svg');
const width = +svg.attr('width');
const height = +svg.attr('height');
const pie = d3.pie().value(d => d.value);
const arc = d3.arc().innerRadius(0).outerRadius(Math.min(width, height) / 2);
svg
.selectAll('path')
.data(pie(data))
.enter()
.append('path')
.attr('d', arc)
.attr('fill', (d, i) => d3.schemeCategory10[i]);
My Results and Impact
- Reduced procurement cycle times through automation.
- Improved vendor performance visibility with analytics and scoring.
- Enhanced security and compliance with robust access controls.
Example Tools and Technologies
- React: User interface development for dashboards and workflows.
- TypeScript: Strongly typed JavaScript for robust, maintainable code.
- Node.js: Server-side logic and API development.
- PostgreSQL: Scalable and reliable database for storing procurement data.
Conclusion
This topic highlights my ability to deliver scalable and secure procurement solutions, tailored to a variety of enterprise needs. By integrating modern technologies and automating critical processes, my solutions enable organisations to streamline operations and make data-driven decisions when it matters most.
