Software engineer. I build backends and the infrastructure they run on.

I founded Medlupi, a healthcare SaaS, and built it end to end: the API, the database, the cloud, the CI/CD, and the product itself.
Before that I led engineering teams, ran DevOps, and cut cloud bills for companies serving millions of requests a day.
I like the unglamorous parts. Keeping things reliable, cheap to run, and easy for the next person to pick up.
- Keep it simple. Reach for boring tech before clever tech.
- Own the whole path, from the commit to production.
- Measure before optimizing.
- If you can't see it, you can't run it. So observe everything.
- Every technical call is a business call too.
Medlupi — healthcare SaaS
Scheduling, records, billing, and multi-tenant clinics. Built and operated solo on AWS: NestJS and PostgreSQL, async work on RabbitMQ and Kafka, a Next.js front end, all infrastructure as code. Took it from an empty repo to paying customers while handling LGPD, tenant isolation, and cost.

Cloud infrastructure and cost
Designed and ran AWS setups where the bill matters as much as uptime. Migrated live systems, wrote everything as code, and wired up observability to see where money and failures actually go. Cut one client's AWS bill by over R$20k/month.
