About Me
Senior Software Engineer · M.S. Computer Science
With 15+ years delivering production systems across fintech, energy, and art technology, I specialize in cloud-native backend engineering, distributed microservices, and AI-powered applications at scale.
My core strengths are .NET/C#, gRPC service design, and Elasticsearch-based data platforms. I lead complex backend projects end-to-end — from architecture and API design through deployment and production support — while staying hands-on with the code.
I pursue new technologies with genuine curiosity. My Azure cloud certification, ongoing AI/ML exploration with Claude Code, and the full-stack CPE Tracker I'm actively building (Kubernetes, GitHub Actions, Stripe, AI PDF scanning) reflect that drive.
Currently available for senior/principal engineering roles and contract engagements. Specializing in .NET/C# backend systems, cloud-native architecture, and AI-powered applications.

Artnet · 2023 – 2024
Leo AI Search
Sole Backend Engineer
Designed and built the gRPC API layer (C#/.NET) enabling Artnet's first natural language and AI-powered image search across the entire global artwork catalog. Engineered production-critical authentication, rate limiting, user search persistence, and BI analytics — bridging fundamental gaps in the vendor's offering. Received Director-level recognition for a feature described as a paradigm shift in how users interact with the art market.

Price Database Modernization
Core Backend Engineer
Core contributor on replacing the legacy price database serving 18M+ auction records used by 95% of art market participants. Migrated data to Elasticsearch, designed gRPC service contracts, implemented the full API layer, and owned multi-environment deployments. Achieved search performance many times faster than the legacy system.
IHS Markit (S&P Global) · 2018 – 2022
Private Loans SPA
Technical Owner
Technical owner for a cross-functional team of 6 responsible for a Single Page Application managing private loans. Drove architecture decisions, code quality standards, and sprint delivery across Vue.js, Node.js, Angular JS, and ASP.NET MVC 5. Integrated complex Java-based third-party APIs and built WCF/REST services across multiple client platforms.
Services
Available for full-time roles and contract engagements.
Greenfield Cloud & AI Development
Design and build modern cloud-native systems from the ground up. Distributed microservices with gRPC, Elasticsearch-based search platforms, LLM API integration, Kubernetes on GCP or Azure, CI/CD pipelines, and production-grade observability.
Legacy System Troubleshooting
Diagnose and resolve issues in mature .NET, SQL Server, and enterprise systems. Performance tuning, database optimization, production incident analysis, and surgical fixes that minimize risk to running systems.
System Modernization
Plan and execute incremental migrations from legacy stacks to modern cloud architectures. Strangler-fig refactoring, data migration, API layer redesign, and technology uplift with minimal disruption to production operations.
