With strong proficiency in Python and hands-on experience building production ML systems on AWS, I am well-prepared to contribute to your marketplace's feasibility prediction and dynamic pricing models. My background includes fine-tuning LLMs and deploying scalable services using Docker and Kubernetes, aligning with your modern tech stack. I thrive in high-autonomy environments and enjoy owning services end-to-end, from PoC to cloud deployment. I am also experienced in collaborating with data scientists and product managers to translate business questions into impactful ML solutions. I am particularly drawn to Cint's AI-native engineering culture and the opportunity to work with Claude Code to accelerate development. I look forward to bringing my analytical skills and passion for machine learning to your team. Sincerely, [Your Name] Copy ### Sample Interview Questions Describe your experience building and maintaining a production ML system end-to-end. What challenges did you face?I built a real-time pricing model using gradient boosting on AWS SageMaker, deploying with Docker and K8s. Challenges included latency optimization and handling data drift, which I addressed with model retraining pipelines and monitoring.How would you approach fine-tuning an LLM for a specific domain task?I would start by collecting domain-specific data, then use techniques like LoRA for efficient fine-tuning, evaluating on a held-out set to avoid overfitting. I'd also consider distillation if deployment size is a concern.Explain a time you had to collaborate with product managers and data scientists to ship an ML feature.I worked with PMs to define success metrics for a recommendation system, then partnered with data scientists to prototype models. I owned the engineering side, ensuring the service met latency and accuracy requirements before production launch.How do you ensure the quality and reliability of ML models in production?I implement automated testing for data validation, model evaluation, and A/B testing. I also set up monitoring for performance metrics and data drift, with alerting for anomalies. Documentation and version control are key.What is your experience with Databricks and how would you use it for ML workflows?I've used Databricks for data preprocessing, feature engineering, and model training with Spark. It's great for scaling compute and collaboration. I'd leverage its MLflow integration for experiment tracking and model registry. ## Company Description Who We Are Cint is a pioneer in research technology (ResTech).
