Custom AI systems for your business.

I build and improve AI agents, voice workflows and SaaS products connected to your business systems. Bring a new product, an integration that needs fixing or a manual process to automate. I handle the backend, interfaces, billing and deployment.

Slivo2025–26 · Voice AI · Commerce

Slivo — Voice AI for e-commerce

I built a voice commerce system that connects Retell AI with WooCommerce product data, on-screen product selection and an order workflow. The SaaS backend handles store isolation, usage accounting and billing.

Lurkee — AI-powered website change monitoring

I built a monitoring pipeline that collects website changes, identifies differences and uses structured AI analysis to produce prioritized findings and reports. The product connects the analysis pipeline with dashboards, alerts and billing.

Engineering range

The product layer around intelligence.

Models create capability. The surrounding system determines whether that capability becomes dependable software, a usable workflow, and a business result.

Model side

AI workflows

Bounded model tasks with explicit inputs, outputs, and review paths.

  • Voice agents
  • Structured output
  • Evaluation loops
  • Tool use
System side

Backend

Durable state and boundaries around probabilistic behaviour.

  • FastAPI / Laravel
  • PostgreSQL / Redis
  • Queues / webhooks
  • Tenant isolation
Human side

Product surfaces

Interfaces where users can inspect, operate, and correct the system.

  • Operator dashboards
  • Admin workflows
  • Reports / evidence
  • Human review
Production side

Operations

The controls that support everyday product operation and maintainability.

  • Billing / usage
  • Retries / recovery
  • Logs / alerts
  • Deployment / handoff

About the engineer

Product judgment, with implementation depth.

I am most useful where a capable prototype has to become a product that other people can operate and trust. I work across architecture, backend, product UI, integrations, deployment, and the uncomfortable details between them.

My earlier work spans native mobile, BLE hardware, health products, SaaS, and e‑commerce. That range now informs how I build applied AI systems: with explicit boundaries, real operator workflows, and respect for production failure modes.

Clear architecture

Make the data, workflows and integration boundaries explicit.

Deterministic boundaries

Use conventional software to contain probabilistic behaviour.

Operators are users

Logs, controls, reports, and review flows are part of the product.

Own the handoff

Deliver software that can be deployed, maintained and extended.
