    About Me

    I'm a Senior Full Stack Engineer and Team Lead with 4+ years of experience architecting and shipping production-grade systems. I've been the sole architect of 5+ end-to-end platforms — designing everything from database schemas and API layers to frontend UX and cloud infrastructure.

    Currently at BVM Infotech (Surat, India), leading a React team and building a DPDP/GDPR-compliant multi-tenant SaaS platform (NsOffice) serving 15+ enterprise tenants — with zero outside help on architecture decisions.

    My recent work centers on LLM/RAG integrations (GPT-4, Gemini, DeepSeek), Apache Kafka event streaming in production, and AI-powered SaaS platforms. I'm actively seeking full-time remote roles globally (US · EU · Middle East) where I can own systems end-to-end.

    What makes me different:

    • Built and shipped multi-tenant SaaS with row-level security, DPDP/GDPR compliance, and zero external architects
    • Production Kafka experience — not tutorial-level
    • LLM/RAG depth: custom pipelines, Qdrant vector search, multi-model routing (GPT-4, Gemini, DeepSeek)
    • Team lead who writes production code daily — not just ticket managers
