Who I am

About me

Full-Stack AI Developer focused on building intelligent, production-ready AI-powered web applications.

Professional Profile

I started in traditional full-stack development and extended that foundation into AI application engineering. Today I design systems that combine solid software engineering practices with intelligent features so AI capabilities sit inside modular architecture, secure APIs, and products that are reliable enough to ship.

How I work

AI Engineering

I apply full-stack engineering practices to AI-powered products with LLM integration, retrieval pipelines, and secure application backends so teams can maintain and extend.

LLM Application Development

Integrating Google Gemini into full-stack apps for multi-turn chat, content assistance, and Q&A flows with clear API boundaries and server-side control of model calls.

Retrieval & RAG Systems

Building RAG pipelines for PDF question answering: document chunking, embeddings, semantic retrieval, and context assembly before grounded LLM responses.

Prompt & Context Design

Designing prompts and conversation context for reliable multi-turn interactions, including history management and structured request/response handling in chat and Q&A products.

Full-Stack AI Architecture

Structuring modular frontends and backends with clear API and data layers so AI features sit inside maintainable application boundaries.

Auth & Secure AI APIs

Implementing authentication and protected API routes so LLM and retrieval endpoints are accessed through controlled, production-minded server logic.

Data & Persistence Layers

Modeling relational data for users, conversations, and application state keeping chat history, auth, and domain data queryable alongside AI workflows.
