AI Data Trainer with expertise in data analysis and process optimization.
What I'm looking for
I am an AI Data Trainer with a strong background in data analysis and machine learning technologies. My journey began with a B.E. in Computer Science, which laid the foundation for my career in technology. I have honed my skills at Amazon Development Centre, where I led quality assurance on annotated AI data to train NLP systems. My efforts in designing scalable training programs significantly improved accuracy and consistency across teams.
Throughout my career, I have demonstrated a commitment to process optimization and problem-solving. At Amazon, I implemented frameworks that identified gaps in data throughput, enhancing overall efficiency. My experience as a Digital Associate further allowed me to leverage data analytics to propose scalable solutions for network inefficiencies, driving impactful changes in real-time data visibility and actionable insights.
In addition to my technical expertise, I have a creative side as a Freelance Bridal Wear Designer, where I managed end-to-end project delivery and developed a client-centric design process. My diverse experiences have equipped me with strong leadership and communication skills, enabling me to thrive in high-pressure environments while maintaining a focus on customer impact and operational excellence.
