Top SchoolNilson Nascimento is a Lead Backend Engineer with 11 years of experience designing and operating payment and billing systems that run at scale, including leading the launch of LavuPay and building billing services used by 5,000+ users across 20+ countries. He combines deep payments domain expertise—card-present, offline, pre-auth/capture, multi-gateway idempotency—with strong event-driven architecture and AWS serverless skills (Lambda, SQS, Kinesis, QLDB). Comfortable as a hands-on technical lead, Nilson has built cross-platform payment SDKs, implemented auditable financial workflows, and enforced TDD and CI/CD practices to eliminate production payment incidents. Now driving backend architecture for CMMS/CRM platforms, he models domain layers with DDD, CQRS, and event sourcing to deliver reliable, auditable systems. Notably, he founded the chuva-io project and applies cryptographically verifiable ledgers (QLDB) to billing for extra financial trust and compliance.
