function authenticateToken(req, res, next) {
const header = req.headers["authorization"];
const token = header && header.split(" ")[1];
if (!token) return res.status(401).send("Access Denied");
try {
const verified = jwt.verify(token, process.env.TOKEN_SECRET);
req.user = verified;
next();
} catch (error) {
res.status(403).send("Invalid Token");
}
}
📊 3. Financial Data Aggregation Engine
Description: A Node.js worker service normalizing and aggregating data from multiple financial sources before storing in PostgreSQL for analytics.
Key Contributions:
- Designed dynamic normalization pipeline.
- Integrated PostgreSQL ORM with fail-safe inserts.
// aggregator.js
function normalizeData(raw) {
return {
eventTimestamp: new Date(raw.time || raw.event_ts),
customerId: raw.user_id || raw.client_ref,
amountUSD: raw.price && raw.qty ? raw.price * raw.qty : raw.total_amount || null
};
}
🐍 Python Automation and Data Engineering
🛒 4. E-Commerce Competitor Stock Scraper
Description: A Scrapy and Puppeteer based scraper system monitoring competitor inventories, using proxy rotation to avoid IP bans.
Key Contributions:
- Custom proxy rotation middleware.
- Scraped data cleaning and validation pipelines.
# middlewares.py
import random
class ProxyMiddleware:
proxy_pool = ["http://proxy1.com:8080", "http://proxy2.com:8080"]
def process_request(self, request, spider) {
request.meta["proxy"] = random.choice(self.proxy_pool)
}
📄 5. OCR Invoice Processor
Description: Python automation using Tesseract OCR and PDFMiner to read invoices and extract structured data with high accuracy.
Key Contributions:
- OCR tuning for multilingual text.
- Regex-based extraction of invoice fields.
# invoice_processor.py import re def extract_invoice_number(text): match = re.search(r"(INV|Invoice|Ref)[^0-9]*([0-9-]+)", text, re.IGNORECASE) return match.group(2) if match else None
📈 6. Automated BI Reporting
Description: A Pandas-based reporting engine generating daily KPI reports from large datasets, emailed automatically through SMTP.
Key Contributions:
- Advanced grouping and pivot table processing.
- Email distribution automation via SMTP.
# reporting_engine.py
import pandas as pd
def pivot_monthly_sales(df):
df["timestamp"] = pd.to_datetime(df["timestamp"])
df["month"] = df["timestamp"].dt.to_period("M")
return df.pivot_table(values="sales", index="category", columns="month", aggfunc="sum")
🛠️ WordPress, E-Commerce and CMS (PHP)
📰 7. Vaawaa.com News Aggregation Platform

"label" => "News Article",
"rewrite" => ["slug" => "news"]
]);
}
add_action("init", "register_news_article");
📦 8. WooCommerce 3PL Logistics Connector
Description: Custom WooCommerce plugin syncing orders with a third-party logistics provider.
Key Contributions:
- Order sync using WooCommerce action hooks.
- Error logging for API reliability.
💳 9. Subscription E-Commerce Platform

// rpc_connector.php
function get_transaction_details($node, $hash) {
$payload = json_encode([
"jsonrpc" => "2.0",
"method" => "eth_getTransactionByHash",
"params" => [$hash],
"id" => 1
]);
$ch = curl_init($node);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
curl_setopt($ch, CURLOPT_HTTPHEADER, ["Content-Type: application/json"]);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
return json_decode(curl_exec($ch), true);

// surah-loader.php (simplified)
$surahId = isset($_GET["surah"]) ? intval($_GET["surah"]) : 1;
$json = file_get_contents("quran.json");
$data = json_decode($json, true);
$surah = $data[$surahId];
// Basmala logic
if ($surahId !== 9) {
echo "Bismillah ir-Rahman ir-Rahim";
}
// Render all Ayat
foreach ($surah["ayahs"] as $ayah) {
echo "" . $ayah["text"] . "
";
}
