What I build: - Django/DRF and FastAPI backends - APIs, auth, role-based permissions, multi-tenancy - Billing and payments - Stripe subscriptions, entitlements, webhooks - Async pipelines - Celery + Redis for ingestion, reporting, long jobs - AI features - Claude API document processing, human-review queues, confidence scoring, RAG - Integrations - Shopify, QuickBooks Online, WebSocket feeds, SQL Server, ERP/PDV systems - React/Next.js frontends when the project needs the whole thing, not just the API Recent work: - Manufacturing intelligence SaaS: multi-tenant Django, Stripe billing, entitlement gates, KPI engine - Shopify analytics dashboard: cohort retention, LTV, async data pipelines - AI document processing SaaS: Claude API, confidence scoring, human review queue - Real-time trade data: Python WebSocket to SQL Server ingestion How I work: I read the spec before I write code, and flag ambiguities before they turn into bugs. I test before delivery, not after. I document what I ship, so you are never dependent on me to understand your own system. Brazil timezone, flexible hours. Stack: Python, Django, DRF, FastAPI, PostgreSQL, Celery, Redis, Stripe, Docker, React, Next.js, TypeScript Best fit: clients with a real product, a clear spec, and a preference for delivery quality over the lowest hourly rate.
