Project : An upgrade with more advanced components was developed by a team of three developers to be the biggest upgrade ever made for the IGNITE AI, which took only two months for delivery, exceeding project deadlines.• A scalable, reliable and high-performance development plan was designed and delivered to IGNITE AI that led to a 100% success rate.• Developed and optimized the backend of an innovative AI-driven software platform capable of automating full-stack application development from client prompts. Implemented a threading process launch system for APIs, significantly enhancing microservice efficiency and job management, resulting in a 20% improvement in API response times.• Contributed to data ingestion and transformation using Gen AI technologies, streamlining data handling processes that supported dynamic application development. Led a three-member team under the direct supervision of Cognizant’s VP, ensuring robust backend functionality that supported scalable, client-specific software solutions.• The source code for IGNITE AI components was developed to high quality which maximized functionality, maintainability while reducing bugs through a serious testing approach by 90%.• Thoroughly testing IGNITE AI’s stability and efficiency by ensuring that there was a benchmark unit validation and optimization to improve its performance at all cost.• Latching thread process systems were designed and implemented so as to facilitate efficient intercommunication among different job layers within micro-services thus making the system faster by 30%.• Creating an intuitive user interface for IGNITE AI assisted in smooth navigation as well as interaction which led to reduction of user errors by 40%.• Integration of several microservices and job layers into one tool resulted in reduced development time and cost for IGNITE AI tool by 25%.
