At Gritworks AI, I architected a multi-tenant identity layer for a B2B SaaS platform, adopted as the canonical authentication service across 5+ downstream microservices. I also built a PII redaction engine that combines OCR and vision-language models to detect and redact fields in financial and legal documents.
I designed an asynchronous document-processing pipeline using SQS, Redis, and distributed workers. It handles 5K+ daily requests and reduced processing latency by 40%.
At Park+, I designed Kafka-based transaction pipelines for India’s national e-toll payment system, processing 2M+ daily payments with exactly-once business outcomes. I also built REST APIs and webhook integrations for 6+ partners.
I led the application-side cloud migration from GCP to Linode, achieving zero downtime across 5+ production services. At Park+, I also optimized passbook and ledger systems serving 100K+ users and developed a configurable Reward Engine that processes 7M+ annual reward payouts.
