What I'm looking for
I’m reaching out to express my interest in this position that is recently posted on your job board. With 8 years of experience in AI and machine learning, I’ve had the chance to work on a variety of exciting projects, from backend development to building scalable ML systems. I’m confident that my expertise in AI and my passion for creating smart, efficient solutions would be a great fit for your team.
At Culture Mind LLC, where I co-founded the company, I led the development of an AI-powered chatbot for kids, focusing on safety and engagement. I worked on the backend, using Python and PyTorch to build scalable systems and deployed the chatbot on the Google Play Store. I also helped establish a cloud-based infrastructure with AWS SageMaker to ensure smooth and scalable model training and deployment.
Prior to that, at Crayon, I worked on AI-driven rendering pipelines and implemented agentic AI workflows that allowed for dynamic, real-time responses in games. I also migrated legacy services from Python to Rust, improving performance and optimizing system efficiency. This project also involved developing AI APIs for automation workflows and speech detection in voice calls, making systems smarter and more responsive.
At Google, I worked across multiple teams to design and deploy ML models for products like Google Search and YouTube. I helped improve model performance and reduced latency, ensuring millions of users had the best possible experience. The opportunity to work on such high-impact products really deepened my passion for AI and reinforced my commitment to building innovative solutions.
I’d love to bring my experience in AI/ML, cloud infrastructure, and full-stack development to your team. I'm excited about the possibility of contributing to your innovative work and solving complex challenges with AI.
Thanks for considering my application. I look forward to the chance to chat more about how my background aligns with your needs.
