πŸš€ Featured Projects

🎫 Support Ticket Routing & Multi-Agent Triage

An end-to-end intelligent ticket triage platform combining fine-tuned transformers with autonomous agent orchestration.

Attribute Details
Stack DistilBERT Β· HuggingFace Transformers Β· PyTorch Β· CrewAI Β· Ollama
Scale Routes tickets across 10 departments
Performance 71% test accuracy on fine-tuned classification head
Security Fully local LLM inference via Ollama β€” zero data egress
Impact Automates the classify β†’ route β†’ respond loop end-to-end
Repository Live Demo on Hugging Face Spaces

A fine-tuned DistilBERT model routes customer-support tickets into 10 departments, connected to a CrewAI multi-agent system with dedicated classifier, router, and responder agents β€” all powered by a locally hosted LLM. Demonstrates production-style ML deployment from model training to agentic orchestration.

πŸ’ Ring of the Middle Earth β€” Distributed Game Engine

A fault-tolerant, real-time distributed system disguised as a two-player strategy game.

Attribute Details
Stack Go Β· Apache Kafka Β· Event-Driven Architecture
Scale 3 stateless engine instances in a coordinated consumer group
Performance Real-time gameplay over a Kafka event backbone
Security Stateless engines β€” no single point of state failure
Impact Full game-state recovery after node termination via event replay
Repository github.com/pxlnstn

Engineered as a distributed system in Go on an Apache Kafka event backbone: three stateless engine instances form a consumer group with leader election, recovering complete game state from Kafka after any node is killed. A hands-on study in fault tolerance, consensus, and event sourcing.

πŸ“Š AI Evaluation Engine

A local RAG application that audits its own reasoning.

Attribute Details
Stack Llama 3.1 (Ollama) Β· ChromaDB Β· Streamlit Β· RAG
Scale Local-first architecture β€” runs entirely on-device
Performance Self-evaluation loop validates every inference
Security 100% local inference β€” sensitive CV data never leaves the machine
Impact Actively prevents hallucinations through AI self-critique
Repository github.com/pxlnstn

A local RAG application that analyzes CV data using Llama 3.1, ChromaDB, and Streamlit β€” enabling the AI to self-evaluate its inferences and prevent hallucinations. Explores trustworthy AI patterns: grounded retrieval, self-verification, and privacy-preserving local deployment.

πŸš— Car Brand Classification

Multi-class visual recognition with CNNs and transfer learning.

Attribute Details
Stack Python Β· CNNs Β· Transfer Learning Β· Computer Vision
Scale 33-class car brand classification
Performance Transfer learning for accelerated convergence
Security β€”
Impact Demonstrates applied deep learning on real-world image data
Repository github.com/pxlnstn

A deep learning project classifying 33 car brands from images using Convolutional Neural Networks and transfer learning β€” covering data preprocessing, augmentation, model selection, and evaluation.
