From pixels to pipelines — I build the systems teams ship on.

Internal libraries, CI/CD pipelines, config-driven architecture — the infrastructure that lets products scale safely.

Internal Tooling

3 Libraries That Became the Team Standard

Designed and shipped a form generation framework, a multi-step wizard engine, and a viewport observer utility — reusable internal libraries that became the standard for how product teams build merchant-facing workflows.

Impact →Eliminated repeated UI patterns across teams. Reduced feature delivery time significantly. Multiple teams adopted these as the default for multi-step flows and form-heavy interfaces.

Zero-Incident Migration Off a Dying Framework

Led incremental migration of a legacy server-rendered monolith and aging React codebases to a modern stack — maintaining backwards compatibility and zero merchant-facing disruptions throughout.

Impact →Zero production incidents during migration. Established migration patterns and rollout playbooks reused across the org for subsequent modernization efforts.

Product Engineering

Ship Features Without Deploying Code

Built the frontend gating logic and shared state models that connect backend configuration classes to merchant-facing UI — enabling safe, gradual feature rollouts without code deploys.

Impact →Decoupled deploys from releases entirely. Product managers control rollout scope without engineering. Instant kill-switch capability for any merchant-facing feature.

DevOps / Infra

Automated Pipeline From PR to Production

Architected multi-stage YAML pipelines for Dev → Staging → Prod promotion. Infrastructure as code with Terraform, container orchestration on Kubernetes (AKS), and Azure API Management with ApiOps publisher pipelines for automated API validation and publishing.

Impact →Fully automated deployment flow with CI gates at every stage. Eliminated manual deployment steps. Decreased production incidents related to deployment errors.

Shipwise — Ship Your Webapp Wisely

Built a 15-skill Claude Code plugin that guides developers through the full webapp launch lifecycle — from idea validation through post-launch growth. Skills auto-load based on what you're working on. Lifecycle hooks catch security gaps and deploy risks automatically.

Impact →Only lifecycle-aware plugin in the Claude Code ecosystem. Covers ground no individual skill does: the intersection of engineering, security, legal, business formation, and growth — orchestrated with phase-aware routing and persistent readiness tracking. Validated with the strongest proof point in the agent skills space: a reproducible Before/After test showing 2× security improvement on the same prompt.

PromptOps — Test Your Prompts Like Code

Built an open-source Claude Code plugin that treats prompts like tested code — evaluate, improve, regression-test, benchmark across models, and execute, all in one session.

Impact →Closes the gap between writing prompts and testing them. Engineers get a repeatable evaluate → improve → verify → run loop without leaving their terminal.

GrimoLink — Mobile App With AI Workflows

Building a cross-platform mobile app from scratch — full tech stack definition, backend APIs, and AI integration. Exploring RAG agent workflows with n8n, Supabase, and OpenAI.

Impact →End-to-end ownership from requirements through architecture, design, and implementation. Exploring the intersection of mobile UX and AI-powered workflows.

What the Claude Code Leak Actually Reveals (It's Not the Prompts)

Apr 2026

The leak exposed the full product architecture of a production coding agent — prompt caching, autonomous loops, permission hardening, multi-agent orchestration, and memory lifecycle management.
