What I'm looking for

I’m looking for a team where I can ship end-to-end—frontend-strong full stack work on AI-native products. I want autonomy, strong testing/CI, real production ownership, and meaningful problems like ERP automation, compliance, and revenue analytics.

I’m a founder-led full-stack engineer with a rare edge for an AI-native ERP: I spent four years inside an ERP company in support, process analysis, and incident investigation, then built my own fiscal-tech SaaS to remove the manual accounting pain.

I currently build and operate two production SaaS products with paying customers, owning the full lifecycle of every feature—from user problem to design, code, tests, deploy, monitoring, and support. Leaf Delivery covers multi-tenant ordering and delivery with storefront/POS/kitchen display, WhatsApp automation, and courier dispatch, while LeafDFe integrates directly with government SEFAZ webservices using SOAP, mTLS, and digital certificates.

I ship end to end with high agency, alone when needed, using modern frontend and backend stacks plus rigorous quality gates (TDD for payment/webhook critical flows, Vitest, Playwright, and CI predeploy checks). I’m also deeply hands-on with observability and incident response (Sentry), progressive delivery (Cloud Run canary), and AI-assisted development (Claude Code).
