I work extensively with Python, advanced SQL, Snowflake, Apache Airflow, dbt, AWS, Databricks, BigQuery, and Azure Data Factory. My focus is on building dependable, production-ready data products that support business decisions. I have delivered solutions across financial services, healthcare, industrial, e-commerce, and education contexts. My experience includes data ingestion, transformation, orchestration, data modeling, feature stores, fraud detection, anomaly detection, and real-time ML inference. I am experienced in integrating LLM and AI capabilities through Snowflake Cortex, Claude API, OpenAI, LangChain, and RAG workflows. I have built document retrieval, classification, biometric verification, and risk-scoring solutions. I prioritize data quality, governance, observability, lineage, security, automation, and measurable operational impact. I am comfortable translating business requirements into reliable cloud-based data and AI systems. I also have hands-on experience with FastAPI microservices, Docker, Git, CI/CD, IAM-based access controls, RBAC, audit logging, and MLOps fundamentals. ## Skills 32 capabilities[Anomaly Detection](https://jobicy.com/talent/anomaly-detection.md)[API Integration](https://jobicy.com/talent/api-integration.md)[Artificial Intelligence](https://jobicy.com/talent/artificial-intelligence.md)[BASH](https://jobicy.com/talent/bash.md)[Cloud Computing](https://jobicy.com/talent/cloud-computing.md)[Compliance](https://jobicy.com/talent/compliance.md)[Data Analytics](https://jobicy.com/talent/data-analytics.md)[Data Engineering](https://jobicy.com/talent/data-engineering.md)[Data Governance](https://jobicy.com/talent/data-governance.md)[Data Lineage](https://jobicy.com/talent/data-lineage.md)[Data Modeling](https://jobicy.com/talent/data-modeling.md)[Data Pipelines](https://jobicy.com/talent/data-pipelines.md)[Data Quality](https://jobicy.com/talent/data-quality.md)[Data Science](https://jobicy.com/talent/data-science.md)[Data Security](https://jobicy.com/talent/data-security.md)[Database Optimization](https://jobicy.com/talent/database-optimization.md)[ELT](https://jobicy.com/talent/elt.md)[ETL](https://jobicy.com/talent/etl.md)[Fraud Detection](https://jobicy.com/talent/fraud-detection.md)[JavaScript](https://jobicy.com/talent/javascript.md)[LLM](https://jobicy.com/talent/llm.md)[Machine Learning](https://jobicy.com/talent/machine-learning.md)[Microservices](https://jobicy.com/talent/microservices.md)[MLOps](https://jobicy.com/talent/mlops.md)[Python](https://jobicy.com/talent/python.md)[R](https://jobicy.com/talent/r.md)[RAG](https://jobicy.com/talent/rag.md)[RBAC](https://jobicy.com/talent/rbac.md)[Risk Scoring](https://jobicy.com/talent/risk-scoring.md)[Serverless Architecture](https://jobicy.com/talent/serverless-architecture.md)[SQL](https://jobicy.com/talent/sql.md)[Stored Procedures](https://jobicy.com/talent/stored-procedures.md) ##
