What I'm looking for

I’m looking for a role where I can build scalable backend systems and ETL/data tooling in cloud-native architectures, pairing strong engineering fundamentals with GenAI to improve reliability, performance, and delivery speed in a collaborative team.

I’m a Senior Software Engineer who designs and ships cloud-native systems—from backend APIs and operational tooling to data/ETL workflows. I focus on architecture, reliability, and measurable performance gains for real users and clients.

At Useready, I led the design and development of a custom Tableau migration CLI tool for ETL pipelines, defining the architecture and improving migration time by 150%. I also built Tableau Cloud exclusive Prep Flow support and enhanced migration tooling with secure datasource-credential migrations, using LLMs/GenAI to achieve about 75% efficiency improvements overall.

Previously at Multipl, I developed a flexible mutual fund platform and built a custom admin panel that reduced ticket resolution time from 2 days to 2 hours. I implemented caching (Redis and application-level), optimized delivery with CDN configurations, and migrated monolithic cron jobs to AWS serverless (Batch, Fargate, EventBridge), improving resilience, scalability, and cost by 35%.

Earlier at Sezzle, I owned the payments domain and designed a scalable payment solution handling 1,000+ transactions/day. I integrated Razorpay, Cashfree, and Nupay, reducing payment failures by 40%, and pioneered a credit scoring model to mitigate risk by 80%.
