At Elogiou, I built and shipped a testimonial-collection SaaS from scratch, integrating Laravel, Inertia, and Vue. I also developed an AI-powered interview pipeline that uses WhatsApp to ask customers strategic questions and extract testimonials.
I process 1,000–5,000 payment events daily through webhooks and handle 300–500 LLM API calls per day. I implemented rate limiting, queue management, Redis-based distributed locking, and webhook idempotency to prevent duplicate executions and race conditions.
At LS Concursos, I developed features for a study-prep platform and built payment flows with Pagar.me for subscriptions, recurring billing, one-time charges, and invoice generation. I also contributed to student planning and a 3D avatar customization feature.
Earlier, at Adoorei, I built payment gateway integrations and a multi-agent WhatsApp support system. At Codigo Girls, I built a loyalty and cashback platform that grew from an MVP in one pilot store to 50 retail stores and 300k+ users, and developed an anti-fraud system.
