About

Software Engineer | Python Whisperer | AWS Adventurer | API Crafter | Cybersecurity Explorer Passionate about clean code, smart automation, and making backend systems behave. With 3+ years of experience, I’ve built APIs that don’t crash, automated processes that saved people from late-night debugging, and wrangled data like a pro. I’m not a “by-the-book” kind of engineer — I believe in hands-on problem solving, experimenting, and learning by doing. Whether it's backend optimization, automation, or security workflows, I prefer getting into the system and figuring it out in real time. 🔧 What I’ve Worked On: 🕸️ Scraped structured data from 50+ e-commerce sites using Selenium, powering real-time analytics ⚙️ Built and automated ETL pipelines in Python for fraud detection and large-scale data processing ☁️ Managed backend workflows on AWS Lambda, S3, and CloudWatch, reducing manual ops and boosting reliability 🔐 Developed security automation tools for IP blacklisting and alerting systems 🛠️ Created robust Flask APIs for ingesting and aggregating live data 📊 Optimized complex SQL queries for faster insights and dashboard performance 🛡️ Actively exploring cybersecurity — currently learning about threat detection, vulnerability assessments, and cloud security through hands-on labs and industry courses (Google, Deloitte, LinkedIn Learning). Let’s connect if you believe in learning by building, love solving real-world problems, or are working on something cool in backend, data, or cybersecurity!
