Principal Software Architect | High-Performance Systems & Lean MVPs I don’t just write code; I build systems that solve expensive problems. As a Staff-level Engineer and the Owner of Syntactic Sugar LLC, I specialize in high-performance refactoring, API architecture, and rapid MVP delivery. With over 7 years of experience—ranging from early-stage startups to driving multi-million dollar DoD contracts—I’ve developed a "no-nonsense" approach to engineering: build what matters, optimize what hurts, and skip the over-engineering. Why clients work with me: Proven Performance: I’ve reduced processing overhead by 80%, shrunk cloud processing times from 12 hours to 30 minutes, and improved page load times by over 97%. Architecture that Scales: I have architected entire API platforms from scratch using Node.js, TypeScript, and GraphQL, handling tens of thousands of records with 100% accuracy. DoD-Level Security: I’ve led development for Department of Defense contracts, implementing rigorous security standards and real-time 3D modeling platforms. Communication & Reliability: Based in Littleton, CO (MST), I am highly responsive and effectively work across EST and PST time zones. I hold a 100% Job Success Score on Upwork because I prioritize clear, proactive communication. Technical Expertise: Backend: Node.js, TypeScript, C#, Python, Java, GraphQL/Apollo, NestJS. Cloud & DevOps: AWS (ECS, S3, SQS, RDS), Docker, CI/CD (CircleCI, Terraform), Git. Frontend: React, Vue, Electron, and real-time WebSockets. The "Game Dev" Edge: Beyond enterprise software, I am an experienced indie game developer. This background in systems programming, shader scripting, and real-time character controllers allows me to approach complex logic and performance optimization from a unique, highly mathematical perspective that traditional web developers often miss. Whether you need a lean MVP launched in 2–3 weeks or a legacy system refactored for massive scale, I deliver production-ready results without the bloat.

Feel free to discuss how I can contribute to your next project.

I solve tech problems that don't have obvious solutions. I work in the land of "where do we even start," "I have this idea but I don't know what to do with it," and more commonly the past few years "I have this plan from an AI, will it work, how do I actually build it?" If you've had those experiences, send me a message. In the past 15 years I've solved data problems, automation problems, pipeline problems, scaling problems. I've solved government databases like EDGAR or SBA being insufficient, I've solved non-profit workflows being inefficient. I've solved "what kind of orchid is this?" and "how many people are watching our content across 4 social media platforms?" I can help you ideate on why a solution is good and how it scales, pitfalls to avoid, caveats, tradeoffs. I can be a stand-in CTO who makes tech decisions for a special project. I can solve a single piece of your pipeline or manifest the entire idea into something functional, measurable, and scalable. In 15 years I've wired up thousands of API integrations, automations, and data pipelines. I've been using AI the past few years where it makes sense and keeping the human in the loop where it doesn't. I can help you figure that out too for your business or idea.

I'm a technology consultant with more than 35 years of experience designing enterprise software, modern data platforms, and AI-powered applications.
