I’m a Software Developer Engineer (SDE-1) at Hyscaler (NetTantra Group), where I build
AI-powered systems, full stack applications, scalable backends, and high-performance data pipelines for enterprise clients.
I’ve engineered RAG systems that reduce LLM hallucinations by 65%, developed document processing pipelines for 10,000+ documents, built multi-threaded job systems handling 10K+ records/day, and developed applications served to 100K+ users.
- RAG systems using vector databases (pgvector, Redis Vector)
- Hybrid search (dense + sparse) with 40% faster retrieval
- LLM integration (OpenAI, Anthropic, Mistral)
- Document processing pipelines (Docling + Celery)
- Embedding workflows, metadata tagging, semantic ranking
- Enterprise applications with Next.js, React, Tailwind, Redux
- Real-time chat, notifications, WebRTC, WebSockets
- Scalable frontends optimized for performance & SEO
- Node.js, Nest.js, Express.js
- Distributed workers using Node.js Worker Threads
- REST & GraphQL APIs
- Role-based access control, authentication, multi-tenancy
- High-volume data processing (10K+ records/day)
