Current focus

Building Voxa, a production-oriented AI receptionist SaaS for barbershops and local service businesses: telephony, workflow orchestration, Postgres-backed state, provider integrations, safe worker execution, and operational documentation.

Selected work

The strongest example is Voxa: a focused vertical SaaS project built around business workflows, not a generic AI demo.

Voxa

An AI receptionist system for barbershops that handles inbound calls, validates appointment intent, uses canonical database state, and executes provider operations through controlled worker paths.

How I work

I use AI as leverage, but the important part is the system around it: context quality, memory, documentation, review loops, and clear ownership of technical decisions.

Product engineering

Turn ambiguous business problems into concrete user flows, data models, workflows, and deployable product surfaces.

Backend workflows

Design API-driven systems with persisted state, controlled mutations, retries, provider truth, and traceable execution.

AI-assisted development

Use Claude Opus, Codex, Gemini CLI, Kimi, project memory, reusable context, and model selection by task.

Relevant strengths

This site is intentionally tailored toward full-stack/product roles where ownership, implementation speed, production debugging, and practical SaaS thinking matter.

Frontend/product surface React, TypeScript, JavaScript, product UX thinking, and ability to translate workflows into usable interfaces.

Backend and integrations Postgres/Supabase, API orchestration, provider integrations, worker execution, and reliability boundaries.

Operational mindset Industrial operations background, troubleshooting discipline, documentation habits, and comfort with real-world systems.

Creator/platform context Music producer background with experience in digital platforms, creator workflows, online distribution, and audience-facing products.
