I'm a Java Backend Developer and a Graduate Student in Computer Science at the University of Dayton, with 5+ years of professional experience building, modernizing, and supporting business-critical, high-volume enterprise applications.

• 🔭 I specialize in Java, Spring Boot, microservices, and event-driven systems
• 🌱 Currently leveling up in Go (Golang), Swift / iOS, and AR/VR
• 🏗️ I care about clean, maintainable code and systems that scale reliably
• 🤝 Comfortable across the full SDLC — design, build, test, deploy, and support
• 💬 Ask me about Spring Boot, REST APIs, Kafka, Docker & CI/CD

Microservices · REST APIs · Event-Driven Architecture · Agile / Scrum · TDD · CI/CD

• 🧩 Designing and developing Spring Boot microservices for high-volume transactional systems

Runnable event-driven order workflow built with Java 17, Spring Boot 3, Kafka, PostgreSQL, and Redis, with its delivery guarantees and limitations documented explicitly.

• Event-driven architecture with Apache Kafka for async order processing
• Bounded idempotency handling with atomic Redis event claims
• Circuit breaker pattern with Resilience4j for fault tolerance
• Prometheus metrics + custom business metrics for observability
• JUnit 5 + Mockito with 22 passing tests and an enforced whole-project JaCoCo gate
• Reproducible k6 workload with no unsupported production throughput claims
• Docker Compose + GitHub Actions CI/CD pipeline
• Tech: Java 17 Spring Boot 3 Kafka PostgreSQL Redis Docker Prometheus

AI-powered news categorization system that classifies articles into Business, Politics, Sport, Tech & Entertainment.

• Hybrid CNN-LSTM model for feature extraction & sequential learning
• Text preprocessing with Word2Vec / GloVe embeddings
• ~90% accuracy with precision, recall & F1-score metrics
• Flask / FastAPI backend + Streamlit frontend

A scalable relational database system replicating Instagram's structure for users, posts, comments, likes & social interactions.

• Normalized MySQL / PostgreSQL schema with indexing
• Secure authentication & role-based access control
• SQL triggers & stored procedures for automation
• RESTful API integration + cloud deployment (AWS RDS / GCP Cloud SQL)

Plus documentation fixes for WireMock's docs site and the Spring Guides.
