As Senior Software Engineer, I formulated scalable data systems using the datasets using machine learning techniques to enhance the user experience. I also developed models for tackling complex business challenges, including feature engineering, model training, and performance evaluation.In this role, I created predictive algorithms and models, improved data quality, and reviewed the dataset's patterns to obtain insights. I also led and delivered software engineering projects single-handedly. Additionally, I set up a statistical model for discovering anomalous mouse clicks and blocking bot clicks.During my association, I created a scoring-based system with a random forest classifier to identify humans based on mouse movement. I also established a KAFKA traffic pipeline module to separate mobile, API, and JS traffic. Moreover, I prepared a Selenium and Scrapy framework to auto-scrape site material for attacking competitor-protected sites.In addition to the above, I created a module to identify DDOS attacks and provided a unique signature with a confidence score to mitigate them using K-Means clustering. I also prepared an ARIMA module to predict slow-attacking bots.Furthermore, I undertake the Crypto-based captcha-less bot mitigation to slow baseline algorithm bots.

As Technology Analyst, I prepared the Java framework for another TestNG account's automation. I also developed a Python framework for banking domain automation with Selenium for the web, Appium for mobile, and Python requests for API. In addition to this, I formulated a CICD-supporting Jenkins pipeline for the automation suite.During my association, I also enabled and strengthened the simultaneous execution capabilities for cross-browser testing with the same test suite in different browsers. I also delivered training to manual testers in automation.
