Howdy, I’m Trinity Klein

I’m a Cloud Developer with a B.S. in Computer Information Systems (Cum Laude) and AWS Cloud Practitioner certification. I build cloud-native and full-stack systems with a focus on automation, infrastructure as code, and scalable application design. My work spans serverless AWS projects, CI/CD pipelines, and production-style applications that solve real operational problems.

Featured Projects

• Cloud Resume Challenge - A fully serverless, end-to-end web application showcasing cloud-native design and automation. Built on AWS using S3, CloudFront, Lambda, and DynamoDB, deployed via Terraform with GitHub Action CI/CD pipelines.
• Innov8 Barber Shop Management System - A full-stack web application built for a local barbershop owner, featuring a public-facing site and a private dashboard to manage clients, services, and appointments.
• Enterprise Data Platform - A full-stack data platform built with Vue 3 and Node.js to manage events, services, and client data. Features role-based access control, interactive data visualizations, and a modular MEVN architecture designed for maintainability and real-world scalability.
• IT Asset Management Database - Built a robust Oracle PL/SQL database with stored procedures, triggers, and performance tuning.
• Multi-Step Cyber Attack Simulation - Conducted a multi-step attack simulation in a TryHackMe lab environment.
• College Apartment Network Design - Designed a full network architecture with redundancy, performance optimization, and security considerations.
• GoGreen Insurance Cloud Architecture (design-only) - Three-tier AWS architecture for secure, scalable file storage; includes diagrams and proof-of-concept notes.
