Open to Applied AI and software engineering roles · Global remote teams

I build AI products that survive production.

Applied AI Engineer and software engineer shipping end-to-end products — now focused on the systems around AI: workflows, APIs, voice, security, billing, observability, and deployment.

Selected systems

Work that carries real operational weight.

Four different AI product problems. Each case shows the surrounding system: product decisions, integration boundaries, failure modes, and evidence — not a list of model names.

Pilot2025–26 · Voice AI · Commerce

A voice sales layer for complex e‑commerce.

A multi-tenant product that lets shoppers talk through high-consideration purchases while the interface responds with live product options and an order flow.

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 keep a product useful after the first successful demo.

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

Engineering beyond the AI layer.

Mobile releases, BLE protocols, offline-first products, commerce, and client delivery are supporting evidence: the engineering depth existed before the current AI cycle.

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.

Evidence over theatre

Show the system, its status, and what can actually be verified.

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

Deployment and maintainability matter as much as the first demo.

Working notes

Ideas tested against real systems.

Short technical positions from current project work. These will connect to deeper writing as the new portfolio becomes the evidence layer behind LinkedIn.

Production AI

The model is the smallest part of the product.

What has to exist around an AI workflow before real users can depend on it.

Voice systems

A voice agent needs a visual and operational layer.

Why conversation alone is not enough for commerce, booking, or support.

Security

AI security starts in the browser more often than teams expect.

Configuration evidence, exposed data, and unsafe rendering before exotic attacks.
