- Designed and built Job Agent and Pilot, agentic systems that use tools, persistent context, external research, decision rules, repository inspection, state tracking, outcome verification, and adaptive multi-step workflows to create career and software-development artifacts.
- Modeled four subscription tiers against Stripe and SMS costs, then implemented hosted Checkout and Billing Portal, plan changes, signed idempotent webhooks, SMS reload purchases, entitlements, and operator reconciliation.
- Designed trust-sensitive onboarding around privacy and delivery limits, user verification, ally consent, and Telnyx delivery-state plus STOP, START, HELP, and SAFE workflows.
- Built a durable check-in engine with timezone-aware recurrence, transactional notification queues, database leases, retries, staged escalation, acknowledgement, and resolution workflows.
- Deployed and operate the ARM64 AWS production stack with health-gated releases, validated deployment automation, rollback procedures, and end-to-end logging, metrics, tracing, and dashboards.
- Build client tools, database tuning, and API integrations in Ruby, Python, Go, JavaScript, and TypeScript.
- Built Playwright end-to-end tests for Safety Ally's critical user workflows, complementing backend and integration coverage with browser-level release validation.
