End-to-end data pipeline development and optimization ? Legacy to cloud migration expertise ? Real-time data processing and automation ? Performance tuning and cost optimization ? Data governance and security implementation ?

Strong problem-solving and analytical skills ? Cross-functional collaboration and Agile delivery CAREER GOAL Seeking Senior Data Engineer or Snowflake Architect roles to leverage cloud migration expertise and build scalable data platforms.

I am a Data Engineer with around 3+ years of experience specializing in Snowflake, SQL, and cloud-based data warehousing solutions. I have strong hands-on experience in ETL/ELT development, migrating legacy systems such as SSIS to Snowflake, and building scalable data pipelines using Snowflake SQL, tasks, streams, and stored procedures.

I have worked extensively with cloud storage (AWS S3 / Azure ADLS), data ingestion using COPY INTO and Snowpipe, and incremental data processing. I am experienced in data modeling (facts and dimensions), performance tuning, and writing complex SQL queries using window functions, CTEs, and analytical logic for reporting and analytics.

Additionally, I have exposure to dbt modeling, testing, and environment variables, along with basic Python scripting for data extraction and automation. I collaborate closely with business and reporting teams, supporting tools like Power BI, and ensure data quality, governance, and security best practices. I am actively seeking opportunities where I can contribute to building reliable, high-performance data platforms.

I hold a Bachelor’s degree in Engineering / Technology, where I developed a strong foundation in databases, programming, and software engineering concepts. My academic background supported my transition into data engineering, strengthening my understanding of SQL, data structures, system design, and analytical problem-solving, which I apply in real-world data warehousing and cloud projects.
