Aarushi Gupta

I’m a Senior Software Engineer with 4+ years of experience building high-scale backend systems and AI-powered microservices. I focus on practical AI engineering—prompt engineering, agentic AI, and multi-model LLM integration—backed by solid system design and reliability practices.

At Bik.AI, I architected and deployed core AI chatbot features for 10K+ monthly active users, including an automated AI template workflow and usage-based AI billing to monitor and monetize LLM token consumption. I authored and fine-tuned agent prompts to reach 95% intent recognition accuracy, and built a multilingual prompt framework that supports 50+ languages—driving a 25% increase in international user retention.

Previously at BillDesk, I delivered Java/Spring Boot REST APIs with Apache Kafka for event-driven processing of 1M+ daily transactions, reducing latency by 40%. I integrated caching (Redis and Caffeine), improved security posture with AES/RSA encryption across 5+ distributed databases, and helped establish 99.99% uptime through custom monitoring and alerting—while mentoring engineers and applying TDD to cut critical feature development time by 20%.
