Pleione — SaaS ERP for environmental compliance · Jan 2026 – present Sole engineer on a six-module platform for environmental consultancies: CRM, sales pipeline, licensing and document workflows, deadline calendar, projects/kanban with time tracking, and accounts payable/receivable. The core problem is regulatory: a missed license deadline carries legal and financial exposure, so the system consolidates obligations across licenses, conditions and contracts into a single authoritative calendar.
VendON — multi-tenant SaaS ERP for order management Next.js, React, Supabase (PostgreSQL, auth, Edge Functions), Redis caching, Mercado Pago subscription billing with webhook-driven state, and a RESTful API documented to the OpenAPI spec.
Nexo and Pleione are private (commercial products). Happy to walk through architecture and code in a conversation.
