Maurício Scopel — Senior Backend Engineer

about

Backend depth, end-to-end range.

I'm a senior backend engineer with 10+ years designing and building scalable microservices in Java and Spring Boot. I specialize in cloud-native architectures on AWS, event-driven systems, and high-traffic platforms — and I've delivered end-to-end solutions, from system design to infrastructure, for international companies across e-commerce, music, and sports.

I also build and ship whole products on my own. Two published mobile apps and an EEG deep-learning thesis round out a backend core with real range — the kind of breadth that comes from owning a product from the database to the app store.

Back End Software Developer · Remote

Built most backend features for a sports-prediction platform from its early stages, growing it to ~15,000 users within a year of launch and enabling several in-platform sponsorship deals.
Architected the end-to-end backend for a game-statistics platform in Java/Spring Boot on AWS — owning the full lifecycle from system design to infrastructure provisioning via CloudFormation — and integrated Stripe and Apple (iOS) payments.
Designed a multi-layered auth stack: JWT login with refresh-token family rotation and reuse detection, email-verification gating, OpenID Connect for Google sign-in, and RBAC to gate premium features.
Hardened the platform against abuse with two-tier per-user rate limiting (Bucket4J via Valkey), captcha on public endpoints, secrets in AWS Secrets Manager, and signature-verified third-party webhooks.

Back End Software Developer · Remote

Delivered features and resolved production issues in the data-integration module of a US hospitality platform, keeping data in sync across a PostgreSQL/AWS microservices architecture.
Automated a legacy monolith's test-suite migration from JUnit 4 to JUnit 5 with an open-source source-to-source translator — applying compiler techniques (an ANTLR grammar for Java) to parse and rewrite tests — eliminating hundreds of hours of manual refactoring.
Maintained and extended the integration layer between a legacy monolith and modern microservices using AWS SNS for event-driven messaging.

Back End Software Developer · Remote

Engineered multi-source query systems combining DynamoDB with search engines (Algolia, TypeSense) to power dynamic product discovery on a high-traffic music e-commerce platform.
Designed a Merkle-tree reconciliation algorithm to cheaply detect sync drift between the DynamoDB source of truth and the Algolia index, pinpointing only obsolete records to avoid costly full re-syncs.
Architected a GraphQL Backend-for-Frontend (BFF) layer that abstracted microservice complexity into a unified, consumer-friendly API.
Orchestrated event-driven communication across services with AWS SQS/SNS and implemented webhooks via API Gateway for third-party integrations.

Optimized a Spring Batch credit-analysis pipeline for Riachuelo by tuning JVM parameters and refactoring processing logic to meet strict execution-time constraints.
Extracted the shopping-cart module from a legacy monolith into a standalone microservice at Lojas Colombo, improving maintainability and enabling independent deployment.
