Experience

I lead the development of Natura Vitalis, Multidrop's new product: an MLM platform with ERP logic, rank progression and downline management.

I rebuilt the MLM system around a dedicated commission engine, modeled with DDD.

Commission calculation used to take a full day to refresh. I replaced the batch process with an event-driven model on BullMQ: payment, order edit, price and points events go into a queue and, starting from the affected user, recalculate points and commissions for everyone above them in the network, in cascade. Updates now take a few minutes.

Persistence with Prisma and payments with Unzer.

Backend for Multidrop's platform (digital products and affiliates), with REST APIs in Spring Boot and Stripe payments.

I migrated course video hosting from Vimeo to our own setup on a Google Cloud bucket.

I built the video transcoding microservice in Python with FFmpeg, orchestrated by Pub/Sub queues with idempotent processing — queue redeliveries never produce duplicate transcodes. Services containerized with Docker.

Built financial reports in SQL (income statement, cash flow) on top of the Sankhya ERP and created BI dashboards that brought together the data management needed for decision-making, while supporting ERP deployment and customization.

Worked on the modernization of the Internal Affairs Office system, rewriting the project, originally in plain PHP, with Laravel and Vue.js.
