Development of AI-driven automation systems

Al Software Engineer
Al Software Engineer
  • Led the development of AI-driven automation systems thatimproved production efficiency, minimized downtime, andoptimized resource utilization across the factory.
  • Designed and deployed machine learning models usingPython, TensorFlow, and scikit-learn to forecast productiondemand, detect workflow bottlenecks, and predictequipment failures before they occurred.
  • Developed predictive maintenance solutions that analyzedIoT sensor data to identify anomalies and schedule proactiveinterventions, significantly reducing unexpected equipmentbreakdowns.
  • Built AI-powered dashboards and analytics tools to visualizekey performance metrics, enabling data-driven decision-making for factory managers.
  • Designed and developed backend services using Java SpringBoot and RESTful APIs to integrate machine learning modelsinto enterprise systems, ensuring secure, scalable, and high-performance data processing.
  • Collaborated with software and operations teams tointegrate AI insights into web platforms built with React,Next.js, NestJS, PostgreSQL, and Spring Boot?basedmicroservices, ensuring smooth deployment and systemscalability.
  • Implemented authentication, authorization, and API securityusing Spring Security and JWT, strengthening systemreliability in production environments.
  • Enhanced HR management modules by implementing AI-based performance and attendance analytics, improvingworkforce optimization and reporting accuracy.
  • Applied A/ B testing and reinforcement learning techniques tofine-tune production parameters, achieving measurableefficiency gains and a 15% increase in processthroughput. Strengthened expertise in MLOps, data pipelinedesign, containerization (Docker), CI/ CD automation, anddeploying AI solutions in real-world industrial environments.
