Staff Software Engineer · Eduzz

The technical reference for a nine-person team at one of Brazil's largest creator-economy platforms (~R$1.2B annual GMV). I own the commercial operation's automation and data layer end to end, and the technical calls that come with it.

• Multi-program scoring engine (Strategy Pattern core, 40+ rules) that replaced manual commercial decisions with an automated ranking pipeline, with Bayesian confidence-weighting so low-volume sellers aren't judged on noisy data.
• The automation and observability layer for chargebacks and disputes across four payment providers (Stripe, Pagar.me, Mercado Pago, Iugu), built idempotent on top of unreliable webhooks.
• The product-pipeline API the commercial team runs on: parallel fan-out across four databases (SQL Server, MySQL, MongoDB, Postgres), with a cache that cuts latency 50-70% and database load by roughly 90%.
• Config-driven qualification engine, 2M+ qualifications processed, publishing completion events to RabbitMQ through an idempotent outbox.
• Living documentation for the automations: a read-only pipeline turns the HubSpot and Botpress APIs into versioned docs, and an AI layer fills intent without inventing structure.
• I ship daily with AI coding agents (Claude Code) and own the prompts, evals, and review loop that keep that code production-safe.

Founder & CEO (exit) · Orbit, acquired by Eduzz

I founded Orbit Pages, a landing-page SaaS for digital creators, and ran it to the acquisition.

• Built the product solo. Eight months to first sale, then 67,000 free users, 1,500 paying customers, and R$100k+ MRR.
• The planned VC round fell through in the pandemic and I took the company to profit without it: MRR from R$30k to R$100k, and annual-plan revenue from 20% to 80% by reworking pricing and defaults, with zero new features.
• Stayed lead architect throughout. Re-platformed the V1 onto S3 and Vercel for pages, with the critical integrations on Kubernetes, while running the business, investors, and support. It still runs today, years after the exit.
• Grew the team from 2 to 18 and back to the lean 7 that ran it to the acquisition.

Full-stack engineer · on my own

Hundreds of projects on my own. I started building websites to spec and ended up designing the payment systems clients trusted with real money. PHP, JavaScript, WordPress, React, Vue, Node.

• Custom checkout (Doutor Nature): five months to move the client off a closed full-suite provider and keep the installment interest. Gateways behind one interface, idempotency keyed on cart and product, reconciliation against the processor API. ~R$3M in its first full production month.
• A bitcoin-transacting store, from scratch, in raw PHP.
• Selected clients: Bruno Souza, the Java Champion, who trusted me with his businesses; ACE Startups, engineering for Natura, Banco BMG, and Algar Telecom; and TDC, Brazil's largest developer conference.
