Sashi Kanth

I am a Senior Lead Engineer (graduated from IIT with a Computer Science degree) with 10 years of experience in architecting and scaling robust microservices-based platforms. My technical toolkit spans Node.js, Express.js, ReactJS, PostgreSQL, AWS (Lambda, S3, Batch, SQS), Kafka, Redis, WebSockets, Docker, and real-time event-driven systems. Key Highlights At Onesaz (EdTech), I architected and delivered a scalable Learning Management System (LMS) serving 100K+ students across 33 institutions (tenants). I implemented an authentication and authorization microservice to be used across the eLearning application, enforcing a secure one-device-one-session policy. I also integrated keystroke dynamics analysis via Kafka and AWS Lambda, enabling real-time behavioral insights and increasing product value and revenue. At Air.inc (Lead Backend Engineer), I spearheaded the migration of 50+ TB of digital assets (videos, audio, images, documents) using optimized ETL pipelines. I designed and implemented serverless pipelines (AWS Lambda, S3, Batch) to automate video transcoding and AI-powered image tagging, significantly improving content management workflows. I have implemented tenant-aware session tracking, admin impersonation features, per-tenant rate limits, and custom schema extensions—all of which directly apply to SaaS platforms. If you're considering schema-per-tenant or ChromaDB integration for AI-based features, I can help evaluate trade-offs and build tooling to manage them at scale.
