About

Shipping AI software, end to end

I'm a computer science student at USF who ships production-grade AI software: a cross-platform LLM healthcare app presented at Google DevFest, a multi-provider AI API server with async streaming inference, and end-to-end web tools built without frameworks. I work hands-on with Python, C/C++, LLM application architecture, and API design — and I'm looking for a software engineering internship building AI and accelerated-computing products.

Projects

01

Ad+ — E-Commerce Advertising Platform

Local-first advertising dashboard shipped as a single self-contained HTML file — zero frameworks, zero backend. Four integrated modules: trending-product tracker, drag-and-drop kanban pipeline, automated outreach-letter generation, and a client-communication organizer.

02

AI Doctor — Cross-Platform AI Healthcare App

LLM-powered mobile app delivering symptom assessment, emergency detection, and provider suggestions — presented at Google DevFest. Dockerized FastAPI backend with layered LLM safety controls: guardrails and JSON-schema output validation.

03

AI-Server — Multi-Provider LLM API Server

Production-ready inference gateway unifying OpenAI, Anthropic, and Google LLM providers behind one REST interface — async request handling, token-streaming responses, Pydantic validation, per-client rate limiting, and structured logging.

04

Email Database

Lightweight in-memory database managing user records — built to strengthen low-level fundamentals in pointers, manual memory management, and data-structure design.

Highlight

Presenting AI Doctor App at Google DevFest

Last November at Google DevFest, we presented our AI Doctor App, the healthcare application my team and I built throughout the GDG mentorship program. Showcasing it to developers and industry professionals, and hearing their feedback on our architecture and user experience, it was an incredible experience.

The event offered more than the presentation itself. Hearing from experienced engineers and founders gave me new insight into model integration, responsible deployment, and how to position technical projects in a professional setting. I left motivated to keep improving the project.
