Portfolio
Selected Projects
Projects spanning production backend systems, agentic AI workflows, and data infrastructure.
Agentic Backend Data Pipeline
Leveraged agentic AI to handle the creation of backend systems for collecting and decomposing data for analytics display — eliminating the need to hand-code each solution. By delegating implementation to the agent, I can drive multiple workstreams simultaneously rather than context-switching between them one at a time. The result is a dramatic increase in throughput: issues that would normally queue up get worked in parallel, and my focus shifts from writing boilerplate to directing the agent and validating outcomes.
AI Coding Standards Enforcement
Built a system of custom skills and structured prompts that teach AI models to internalize and conform to company-specific coding standards. Rather than relying on engineers to manually review AI-generated code for style and convention violations, the AI is trained to understand naming conventions, architectural patterns, file structure requirements, and language-specific rules enforced at the organization. The result is AI-assisted development that produces code consistent with the existing codebase from the first output — shortening review cycles, reducing back-and-forth, and making AI a reliable contributor rather than a source of technical debt.
Claude-Powered Anomaly Detection & Alerting
Integrated Claude directly into production systems to serve as an intelligent monitoring layer. Rather than relying solely on static threshold-based alerting, Claude continuously analyzes system output, logs, and data patterns to identify errors and abnormalities that rigid rules would miss. When something unexpected is detected — whether an unusual data shape, an unexpected failure mode, or behavior outside normal operating parameters — the system automatically fires an alert with a human-readable explanation of what went wrong and why it's notable. This brings LLM-level reasoning to observability, catching subtle issues earlier and giving engineers context rather than just raw noise.
Now
What I'm Building
Current areas of focus — where I'm spending cycles and pushing the frontier.
Adaptive Agentic Workflows
Exploring self-correcting agent loops that observe execution failures and re-route dynamically — no human-in-the-loop required. Focus on real-world reliability over benchmark performance.
MCP Server Integrations
Building Model Context Protocol servers for enterprise systems (databases, internal APIs, ETL pipelines) — making tool-use plug-and-play for any Claude or LLM deployment.
LLM Eval & Observability
Developing a structured evaluation harness for agentic workflows — measuring task success rate, tool efficiency, reasoning quality, and regression detection across prompt distributions.
