What I'm looking for

I'm looking to build reliable AI-assisted and full-stack products where I can own implementation, testing, debugging, and deployment while growing through challenging engineering work.

I build and deliver end-to-end software products as a freelance developer, from backend APIs and data models to web/mobile interfaces, deployment, testing, and maintenance. My work centers on TypeScript/Node.js, PostgreSQL, Linux, Docker, and CI/CD.

I've built Kamikaze AI, a configurable WhatsApp automation backend with LLM integration, webhooks, human handoff, n8n orchestration, HMAC validation, and idempotent processing. I also built Barber Up, a full-stack scheduling SaaS, and a reproducible Python pipeline for EEG machine-learning research across public data from 100+ participants.

Built and delivered complete software products from requirements to deployment, spanning backend APIs, web/mobile interfaces, relational data models, authentication, integrations, testing, and operational workflows. Used AI coding agents as engineering tools to define scoped tasks, inspect changes, reproduce failures, run tests, and iterate until acceptance criteria passed.
