What I'm looking for

I’m looking for a role focused on Generative AI and Agentic AI systems, where I can build production-grade LLM applications, RAG pipelines, and agentic workflows.

I built LinguaAI, a conversational AI backend that brings together LLM inference, speech-to-text, WhatsApp messaging, Redis conversation context, and PostgreSQL persistence. I implemented structured responses for language feedback and scoring, with model fallback for provider rate limits.

At ComfortClick, where I work as a Laravel Developer, I develop backend workflows across commerce, logistics, and supplier management. I also work on carrier integrations spanning international courier APIs, with centralized configuration, token caching, and OpenTelemetry tracing.

Previously, at Mosh E-com Services Pvt. Ltd., I built and maintained backend systems for e-commerce and logistics, including Amazon SP-API integrations and bulk data exports. I’m currently developing a multi-tenant RAG platform with organization-level isolation, JWT authentication, and pgvector retrieval foundations.
