About Me

AI/ML Engineer focused on building AI agents, LLM systems, and production-ready Generative AI applications. I design and develop agentic workflows that combine language models, retrieval, structured data, and external tools to automate complex tasks and solve real business problems.

I work across the full lifecycle of AI systems—from model development and evaluation to RAG pipelines, FastAPI-based services, and scalable deployment. My core stack includes Python, PyTorch, TensorFlow, FastAPI, and modern LLM tooling.

Areas I’m focused on: AI Agents and agentic workflows, Generative AI and LLM systems, Retrieval-Augmented Generation (RAG), Model deployment and inference APIs, End-to-end AI/ML system engineering. I’m always open to connecting with teams working on AI agents, LLM infrastructure, and next-generation AI products

Work Experience

AI Engineer

Jun 2023 - Present

Unitusk Technologies • Vadodara, India

Engineered and deployed client-facing AI applications covering backend architecture, database design, and production deployment across cloud environments. Built low-latency LLM services and model serving pipelines.

Key contributions: engineered a full-duplex audio pipeline that replaced sequential STT → LLM → TTS with simultaneous bidirectional inference, reducing end-to- end response latency from ~1.2s to ~200ms. Deployed services using vLLM, Ollama, FastAPI, Docker and PostgreSQL.

Data Science Intern

Dec 2022 - Jan 2023

Exposys Data Labs • Bengaluru

Supported ML workflows through data cleaning and preprocessing. Gained hands-on experience with data science best practices.

Software Developer

Jun 2019 - May 2021

Emptai IT Services • Surat, India

Worked on key modules of a POS system, contributing to billing, product listing, and inventory screens. Shipped features that went live in production and improved stability.

Implemented offline billing support using local SQLite for resilience during network outages, syncing transactions back to PostgreSQL when connectivity resumed.
