Summary

Product engineer building client-facing platforms, internal tools, and AI-assisted engineering workflows across SvelteKit, TypeScript, cloud infrastructure, and LLM tooling. Built a greenfield insurance workflow platform intended to process roughly $20m in business when fully live, with the codebase designed from the outset for safe, high-standard AI agent collaboration.

Highlights

Built a multi-tenant insurance workflow platform from scratch, covering submission intake, document processing, extraction/evaluation flows, quote lifecycle support, operational tooling, audit history, and controlled deployment into client infrastructure

Designed the repo for agent-assisted team delivery: canonical agent onboarding, local project skills, branch workflow rules, module-boundary guidance, service-layer patterns, code-style rules, MVP readiness gates, and explicit “read docs before changing code” entrypoints

Created a local documentation package that indexes project docs into a SQLite/FTS search layer, giving agents fast, cited access to business requirements, schema notes, communications, workflow maps, meeting notes, and implementation context before touching code

Added guardrail tooling to keep standards high, including import and module-boundary checks, route data audits, runtime configuration checks, release verification/export tooling, required Svelte/type checks, and guidance for keeping routes thin and business logic inside services/packages

Implemented cloud deployment and operational changes across AWS and Azure, including ECS/container app services, RDS/Postgres-backed applications, SES/email infrastructure, storage, secrets/environment configuration, Terraform PRs, DNS, and production debugging

Used browser automation, MCP tools, recall databases, documentation search, and agentic coding workflows to test production journeys, diagnose failures, coordinate parallel work, and preserve review control while moving quickly

Summary

Engineering team lead for a SvelteKit monorepo ecosystem powering AI customer service agents. Led 12 developers across Customer Portal (8) and Smart Agent (4) teams. Primary architect for infrastructure, security, and AI integration decisions across the platform.

Highlights

Built claude-sdk-runtime, an AI customer service agent deployed on AWS ECS for enterprise clients. Reduced average handle time (AHT) by 40% through intelligent skill-based routing across chat, email, and SMS channels

Pioneered AI agent orchestration workflows with Claude Code. Built reusable engineering skills and coordinated multi-agent teams for parallel development across security, infrastructure, and architecture workstreams

Led a major UI architecture decoupling, migrating the primary application from a shared monorepo UI package to shadcn-svelte. Resolved 928 build errors and unblocked 4 dependent applications to ship independently

Migrated the agent builder to Svelte 5, establishing modern reactivity patterns that Claude Code adheres to when generating new code. This reduced bad practices creeping back into the codebase and freed up the team to move faster

Proactively evaluated Vite 8 / Rolldown / OXC toolchain ahead of release, benchmarking build performance and plugin compatibility to prepare the team for migration

Built reusable security middleware for ownership validation across all API routes, and automated GDPR-compliant trace cleanup for AI observability data
