Miguel A. Lopez
I build software people can rely on. For 8+ years, I have worked across C#/.NET backends, full-stack products, real-time systems, and the tools teams use to ship them. Games are one part of that work.
Building software that holds up
Hi, I'm Miguel A. Lopez, a software engineer based in Winter Haven, Florida. I have spent 8+ years building C#/.NET applications, full-stack products, real-time systems, and cloud infrastructure. Game development is part of that work, alongside healthcare apps, internal tools, backends, and AI agent tooling.
My work includes the Medline Unite mobile app and CMS, War In Arms: Prime Forces, and a current CodeStream Studios contract using C#, ASP.NET Core, Kubernetes, and AWS. I stay close to the people using what I build. The real test for me is whether the software solves today's problem without making the next change harder.
Technical Expertise
Full Stack Development
I build web products end to end, from database and API design to the interface people use. That work includes healthcare apps, CMS and admin tools, and products built with React, Next, Vue, and Nuxt.
Backend, Cloud & Real-Time Systems
I build C#/.NET REST APIs and real-time services for authentication, matchmaking, sessions, and state synchronization. I also deploy, monitor, and improve the cloud infrastructure and CI/CD pipelines behind them.
AI-Augmented Engineering & Agent Tooling
I build practical tools around software delivery, including MCP services, code-intelligence indexing, multi-agent orchestration, and AI-assisted review. It is all in service of shipping: these are tools I use in my own software delivery work.
Game & Interactive Systems
I apply the same engineering fundamentals to gameplay, UI, data-driven workflows, backend integrations, and performance-sensitive C++ tooling. I have shipped interactive work across mobile and desktop platforms.
Quality & Team Delivery
I use automated tests, practical reviews, and clear team workflows to keep changes reliable from planning through production.
Professional Experience
.NET Backend Engineer (Contract)
I am helping migrate a single-node instance into a fully containerized C#/ASP.NET Core emulator service with authenticated REST APIs, process supervision, and Kubernetes support for future AWS EKS deployment.
Lead .NET Software Engineer (Contract)
I delivered and supported a cross-platform healthcare sales application for Medline Industries using React, PHP, MySQL, AWS, a CMS, and role-based admin tools.
- Resolved backend data-consistency and deletion issues through local and production testing.
Lead Software Engineer (Tools, Systems, Gameplay, and Network Programmer)
I built and operated a five-service C#/.NET and SignalR platform for authentication, matchmaking, session management, and real-time synchronization.
- Containerized the services with Docker for Kubernetes deployment and supported 3,000 peak production users plus more than 10,000 users during community load testing.
Senior Software Engineer (Systems, Gameplay, and Network Programmer)
I built a modular C#/.NET framework for a real-time multiplayer Unity game using a ScriptableObject-driven ECS, reusable player and AI systems, Photon PUN 2 networking, and custom events.
- Built deterministic maze generation with chunk streaming for the multiplayer environment.
Software Engineer (UI and Gameplay Programmer)
I built Unity/C# UI and gameplay features, C++ serialization and platform systems, and internal tools for game and theme-park projects.
- Collaborated with design, QA, and production teams to deliver and support the work.
