    Although I work on projects which cross a multitude of platforms and disciplines, the core of my passion is solving problems in creative ways. My wide skillset includes skills in web development, data engineering, 3D design, dev/ops, and game development. Although it may seem like I am a jack of all trades, master of none, I believe that this is actually to my benefit. My primary characteristics of flexibility, strong work ethic, and willingness to constantly develop allows me to bridge the gap between different disciplines. Throughout my college studies in Computer Science, I absorbed a lot of expertise that is immediately applicable to creating virtual experiences. Learning about computer graphics, physics, UI design, and computer aided design all enhanced my ability to create user friendly and immersive software. I also learned game engines like Unity and Godot for my own games, in which I implemented features like navigation, threat assessment, and modular unit control. Of course, I have also learned useful 3D modeling skills in my free time in software such as Blender and SolidWorks.

    My name is Matthew Sweeney. I hold four AWS certifications, including the Solutions Architect – Professional, and a Bachelor of Science in Data Analytics from SNHU. I specialize in designing and developing secure, scalable applications that combine modern front-end frameworks with robust cloud infrastructure. I work with technologies such as React, Next.js, Tailwind CSS, Node.js, and TypeScript to build responsive, component-based interfaces. On the backend, I use tools like PostgreSQL, MongoDB, Redis, and DynamoDB to implement performant, flexible data models. I design and deploy infrastructure using serverless architectures, infrastructure as code (CloudFormation, AWS SAM, CDK), and event-driven workflows that include Lambda, EventBridge, and Step Functions. I have developed authentication systems using OAuth 2.0, SAML, and JSON Web Tokens, and I have integrated secure identity flows with providers like Cognito and custom authorization layers. I work confidently within Linux environments and use Git-based CI/CD pipelines to automate deployments and ensure reliability. In the data domain, I understand how to plan and execute ETL workflows, conduct exploratory analysis, and build dashboards using tools such as Power BI and Tableau. I work with geospatial data using PostGIS and GeoJSON, and I apply statistical and machine learning techniques to uncover trends, predict outcomes, and support decision-making. I study system design principles with a focus on building asynchronous, fault-tolerant applications that prioritize performance, maintainability, and security. I approach each project with careful attention to both technical architecture and user experience, and I enjoy solving complex problems through clean, deliberate engineering.
