About Me

I'm a builder at heart—someone who loves turning real-world problems into reliable, user-friendly software. I've completed my M.S. in Computer Science at Auburn University at Montgomery (May 2025), and I've spent the last few years shipping full-stack apps and ML-powered tools that scale.

Prior to my Master's, I spent two years as a Software Engineer at Speeler Technologies, focusing on full-stack development using React and AWS. Recently, I've been diving deep into Cloud Orchestration and building AI applications using RAG architectures to build enterprise-grade solutions.

HGPT: Enterprise RAG Knowledge Base

An enterprise AI search engine that allows users to securely query 10,000+ internal documents in real-time, built with Llama 3 and a custom Retrieval-Augmented Generation (RAG) pipeline.

REPO

LIVE

What it does

•Implemented a hybrid search strategy using ChromaDB, BM25 for semantic vector retrieval, and Reciprocal Rank Fusion.
•Cross-Encoder re-ranking to maximize context relevance, improving accuracy by 50% over standard keyword search.
•Enabled high-performance ingestion pipeline using FastAPI and Celery workers to asynchronously process and chunk large datasets into embedded vectors with Chain-of-Thought reasoning without blocking the UI.

Deploy: Distributed Container Orchestration Engine

A custom container orchestration platform, similar to a lightweight Kubernetes, designed to automatically monitor, scale, and recover failing server nodes in under 30ms.

REPO

LIVE

What it does

•Reduced node failure detection time to <30ms by engineering a custom distributed control plane in Go.
•Built a CLI and Dashboard utilizing Grafana to visualize real-time node metrics, exposing cluster state via RESTful API.
•Ensured cluster consistency and crash recovery by implementing a Write-Ahead Log (WAL) in PostgreSQL, creating a robust failover system for controller outages.
