PriceTracker — Python Scraper + Java REST API

Python, Java, Selenium, XPath, Regex, MongoDB, Flask, Spring Boot, Git, REST API

• Engineered a cross-platform scraper using Python + XPath + Regex to extract high-value data (Price, Shipping, Availability, and Promotions) from leading e-commerce sites Flipkart, Walmart, Tesco and multiple other giant ecommerce websites across EU5.
• Designed a hybrid scraper system (Python for scraping + Java Spring Boot for ingestion API) that processed and stored 100K+ product records with 98.7% accuracy in stock and price data.
• Implemented multi-threaded crawlers using Python to reduce execution time by 65%, enabling near-real-time data updates every 90 minutes.
• Configured custom error-handling rules to improve scraper resiliency and cut down crawler crash rate by 84% during high-volume sales events.
• Developed a performance dashboard to visualize crawl throughput, error trends, and competitor coverage.
• Reduced backend API response latency to through optimized Java Spring Boot controllers and DB indexing (MySQL/PostgreSQL).

Productivity Tracker for QA Automation Teams

Java, Spring Boot, MySQL, JIRA API, Angular

• Developed a productivity tracking dashboard to monitor execution rates, script health, and bug turnaround time for the QA automation team.
• Pulled test execution data from Jenkins and JIRA using REST APIs and displayed analytics via a custom Java Spring Boot API.
• Tracked over 1,000+ test executions/week, measuring test stability, pass/fail rates, and average script execution time.
