Portfolio
Selected Projects
Projects spanning production backend systems, agentic AI workflows, and data infrastructure.
Agentic Backend Data Pipeline
An agent-driven pipeline where Claude builds the backend systems that collect and decompose data for analytics — no hand-coding each solution. Multiple workstreams run in parallel while I direct the agent and validate outcomes instead of writing boilerplate.
AI Coding Standards Enforcement
A system of custom skills and structured prompts that teaches AI models company-specific coding standards: naming conventions, architectural patterns, and file structure. AI-generated code matches the existing codebase from the first output, cutting review back-and-forth.
Claude-Powered Anomaly Detection & Alerting
Claude integrated into production monitoring as an intelligent layer beyond static thresholds. It analyzes system output, logs, and data patterns, then fires alerts with a human-readable explanation of what went wrong and why it matters — context instead of raw noise.
Now
What I'm Working On
Current areas of focus — where I'm spending cycles right now.
Agentic Workflows in Everyday Work
Actively embedding agentic AI into daily work routines and personal projects — not just one-off experiments, but finding where agents can reliably reduce friction, handle repetitive tasks autonomously, and free up mental bandwidth for work that actually requires human judgment.
AI Enablement for Small Businesses
Sharing AI knowledge with individuals and small business owners who want to boost productivity but don't have deep technical backgrounds. Helping them cut through the noise, identify where AI genuinely saves time, and get hands-on with tools that make an immediate difference.
Agentic Apps for Backend Productivity
Building applications that use agentic AI to take over backend work autonomously — letting the agent handle implementation while I focus on architecture, validation, and outcomes. The goal is multiplying what a single engineer can ship in a given sprint.
Coding Standards for Claude
Developing and refining structured coding standards that Claude can internalize — naming conventions, architectural patterns, file organization, and language-specific rules. The result is AI-generated code that fits the existing codebase from the first output, without a round of cleanup.
Self-Correcting Agent Loops
Experimenting with agent loops that observe their own failures and course-correct without human intervention. When a step breaks, the agent diagnoses, re-routes, and retries on its own — pushing toward truly autonomous execution on complex, multi-step tasks.
