Email: mariocesarsenoranis @ gmail.com
Senior full-stack engineer & tech lead, 10+ yrs, Python/Django-first. I ship MVPs that reach production and stabilize/modernize legacy systems without breaking what works. Comfortable across backend, frontend, and infra.
Strong on SaaS, integrations and data flows: Zapier apps (Platform/CLI), ERPs, billing, CRMs, webhooks, ETL — plus LLM integrations (OpenAI/Claude). Years spent making systems talk to each other reliably.
Ex-Zapier (integrations), ex-Tesorio. Experience across SaaS, fintech, and e-commerce.
