About Alex

I help SaaS and product teams build reliable full-stack systems around revenue, operations, data, and automation.

Typical projects:
- Internal tools, dashboards, admin panels, and workflow systems.
- Checkout, billing, subscription, payment, and provider-integration work.
- Product funnels, onboarding flows, CRM/support tooling, and operational reporting.
- Backend/API work with TypeScript, Node.js, Python, PostgreSQL, and cloud infrastructure.
- Practical AI/automation features: triage helpers, review workflows, evals, structured outputs, and agent-facing tools.

I am strongest when a project needs product judgement, data modelling, failure handling, observability, and production follow-through.
