Tathagata Mitra

I am a Senior Data Engineer with 5+ years of experience designing and operating production-grade data systems across FinTech, Insurance and FMCG domains.

My focus is on building data platforms that scale with business growth — systems that are reliable, cost-efficient, observable and easy to evolve as requirements change.

• Design for long-term maintainability, not just short-term wins.
• Batch vs streaming is a business decision, not a tooling preference.
• Cost, reliability and observability matter as much as performance.
• Strong data modeling reduces downstream complexity.
• I treat data platforms as long-lived products, not one-off projects.
