Software Developer at AUT OINTELLI SYSTEMS PVT LTD who shipped Stripe payments, AI email automation, and Snowflake ETL systems.

At AUTOINTELLI SYSTEMS PVT LTD, I shipped production systems across payment processing, AI-driven email automation, attendance analytics, and e-commerce. My Stripe payment integration kept subscription status in sync and helped cut missed payments by 30%.

I built an OpenAI-powered email automation engine for payment reminders and support workflows, cutting manual communication effort by 80%. I also designed an ETL pipeline that fed attendance data into Snowflake for HR analytics.

As a freelance Software Developer, I built a multi-tenant invoicing platform with Stripe payments, PDF exports, and automated overdue reminders, cutting client follow-up time by 70%. I bring an earlier background in mechanical engineering and moved into software through independent study.
