Senior Software Developer / Team Lead @ Finkraft.ai | Backend & DevOps | GenAI/LLM Systems | Ex-Intellicar

About

Tech Lead with 5+ years building backend systems that scale — from real-time IoT telemetry to enterprise fintech platforms. At Finkraft.ai, I lead an 8-engineer team building an invoice-reconciliation platform processing ₹250Cr+ in GST-value invoices for 100+ enterprise clients, including a GenAI-powered OCR pipeline for structured data extraction. I also architected our cloud migration from AWS to Azure, securing $150K in sponsorship credits. Previously at Intellicar Telematics, I built a real-time vehicle-tracking platform ingesting 1M+ data points/day on Kafka and Cassandra, and designed "Trinity," a Go/Fiber microservices platform with an App-Store model for modular deployments. Core stack: Go, Python, Node.js, Kafka, Microservices, AWS/Azure/GCP, Kubernetes. Currently deepening my work in GenAI/LangChain and applying LLMs to production systems.
