Hi, I’m Duane Moody — a principal-level engineer, systems architect, and founder of XRiley LLC.
I design and build distributed systems that prioritize clarity, reliability, and long-term sustainability. My work spans high-volume backend services, financial and operational pipelines, and cloud-native architectures where correctness matters.
I specialize in backend systems that demand reliability, determinism, and scale, including:
- Microservice and event-driven architectures
- Cloud-native and containerized systems (GCP, Docker, Kubernetes)
- Integration-heavy, data-driven APIs
- Developer tooling, workflows, and documentation practices
I work across Go, Ruby, Python, JavaScript, and Node.js — using frameworks such as Rails, Django, Flask, Express, React, and Next.js.
Data experience includes PostgreSQL, Redis, MongoDB, MySQL, Kafka, and Pub/Sub.
I have extensive experience building and supporting software in regulated and high-availability environments, including:
- Migrating legacy systems to modern cloud infrastructure
- Designing deterministic ingestion and financial data pipelines
- Building event consumers, schedulers, and integration layers
- Strengthening test strategies, documentation, and service clarity
- Collaborating with product, architecture, and platform teams
My focus is producing systems and patterns that remain reliable when real traffic and real business constraints show up.
DXR Labs is where I explore architectural patterns, prototype tooling, and run applied engineering R&D. It supports client work, internal experiments, and open-source contributions — creating space to test ideas before they reach production systems.
I work effectively with:
- Engineering teams navigating complexity
- Product and platform groups needing clarity in system design
- Technical leaders seeking grounded architectural insight
- Organizations that require reliability and maintainability in their core systems
- Start with the real problem; everything else follows.
- Clarity over cleverness; reliable systems should be understandable.
- Improve the ecosystem: code, docs, patterns, and processes all matter.
- Deliver iteratively: ship, observe, refine.
