What I'm looking for

I’m looking for a role where I can apply my skills in AI, backend systems, and automation to real-world problems while continuing to learn and grow in a strong engineering environment.

I’m a Computer Science graduate from the National Institute of Technology Calicut, a President’s Scout, and an SII Scholar, with a strong academic foundation including A+ grades in both SSC and HSC. My journey has always combined technical curiosity with leadership—serving as the General Secretary of the Science Club during my early years and later leading large-scale cultural operations as the Proshow Head for Tathva ’24 at NIT Calicut.

As a technologist, I have worked across artificial intelligence, natural language processing, and intelligent systems. During my undergraduate studies, I developed a generative travel recommendation system using BERT that models sequential user preferences and contextual constraints to generate personalized itineraries. I also built NLP models for sequence prediction tasks and explored deep learning architectures such as RNNs and LSTMs for language modeling.

More recently, I have been working on applied AI systems and automation. I designed and implemented an end-to-end Retrieval-Augmented Generation (RAG) pipeline using LangChain, embeddings, and vector databases for domain-specific knowledge retrieval. I also developed an AI-powered Lead Triage and Qualification System that analyzes inbound leads using LLMs, performs intent classification and scoring, and prioritizes high-value opportunities through structured data pipelines and automated workflows. These projects focus on backend system design, API development with FastAPI, scalable inference pipelines, and production-oriented architecture.

I enjoy translating ideas into practical, user-focused systems by working across data, algorithms, and system architecture. My interests lie in building intelligent automation, AI-powered products, and scalable backend systems that solve real operational problems.

My goal now is to grow into impactful tech-management roles—particularly in AI product development, technology strategy, or technical operations—where I can combine engineering thinking with leadership, communication, and execution to help build high-impact technology solutions.
