About

I'm a senior full-stack engineer with over four years of experience building mission-critical transportation infrastructure systems for State Departments of Transportation across the United States. At Mayvue, I engineered government-critical bridge inspection and asset management platforms serving 15+ State DOTs, processing infrastructure data related to over $500 million in annual investment. These systems are used daily by 1,000+ transportation engineers managing American Association of State Highway and Transportation Officials-compliant bridges while meeting strict federal compliance standards (FHWA, NBIS).

My technical stack spans Vue.js, React.js, React Native, C#, and .NET Core across web and mobile platforms. I hold two AWS certifications (pursuing Solutions Architect Professional) and have integrated AI capabilities into production systems using OpenAI API, LangChain, and Semantic Kernel. I'm currently developing MemoryKit, an open-source .NET library providing neuroscience-inspired memory infrastructure for LLM applications—implementing a three-layer architecture (working, episodic, procedural memory) modeled after human brain structures to give AI applications sophisticated context management and learning capabilities.

Since 2020, I've worked exclusively remote across multiple time zones, delivering scalable solutions to complex technical problems in regulated environments working with culturally diverse and international teams.
