🚀 𝐏𝐚𝐬𝐬𝐢𝐨𝐧𝐚𝐭𝐞 𝐃𝐚𝐭𝐚 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫 | 𝐓𝐫𝐚𝐧𝐬𝐟𝐨𝐫𝐦𝐢𝐧𝐠 𝐕𝐢𝐬𝐢𝐨𝐧𝐬 𝐢𝐧𝐭𝐨 𝐃𝐚𝐭𝐚-𝐃𝐫𝐢𝐯𝐞𝐧 𝐑𝐞𝐚𝐥𝐢𝐭𝐢𝐞𝐬. As a results-driven 𝐃𝐚𝐭𝐚 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫 with over 4 years of experience, I specialize in designing and implementing scalable data solutions that significantly reduce costs, improve data processing efficiency, and enhance data retrieval speeds. My expertise spans big data technologies, cloud platforms, and robust ETL pipelines. I am eager to leverage my technical skills and problem-solving abilities to contribute to a leading tech company. At Paytm, I spearheaded cost-saving initiatives, including implementing Zstd compression in Spark jobs, saving $10,000 one-time and $16,000 monthly. Revamping OLAP for the Travel Vertical saved $1,500 monthly and enabled instantaneous dashboard loading. My OLAP solutions for various verticals reduced infrastructure costs by 30% and improved data retrieval speeds by 40%. Transitioning ETL pipelines to Airflow and introducing event-based triggers cut EMR costs by 13%. During my tenure at Translab.io, I enhanced data visualization and integration efficiency, creating data pipelines that significantly improved processing times and throughput. At NextOrbit, I implemented self-service ETL pipelines that reduced manual labor by 40% and boosted processing speed by 25%. My data science solutions increased sales and reduced inventory across multiple verticals, including Fashion, Electronics, and Groceries.
