Hi, I'm Matheus Lucena
I architect and run mission-critical distributed systems on AWS — turning technical complexity into real business value, with millions of dollars in FinOps savings.
Turning complexity into business value
Software Architect and Cloud Specialist with 7+ years of experience designing and sustaining mission-critical distributed systems. Focused on transforming technical complexity into real business value, I work with cloud-native architectures on AWS, process automation (IaC), and a FinOps culture.
Driven by continuous learning and innovation, I apply Platform Engineering and DevOps practices to build secure ecosystems, remove operational bottlenecks, and accelerate delivery and efficiency across multiple engineering teams.
Architecture
- Cloud-native systems
- Distributed design
- Serverless & event-driven
Platform & DevOps
- Platform Engineering
- GitOps & CI/CD
- Policy-as-Code
FinOps & Governance
- Cost optimization
- Well-Architected
- Security & compliance
Professional journey
A track record of building, scaling, and hardening critical platforms.
Stone
- Architectural sustainment and evolution of the Member Get Member referral platform — a core product processing millions in monthly commissions.
- Designed and built highly resilient serverless pipelines with AWS Step Functions, Lambda, and TypeScript to guarantee absolute transactional consistency.
- Engineered high-availability backend integrations targeting zero-downtime deployments and full compliance with financial-sector regulations.
BRQ
- Technical leadership in systems modernization, migrating mainframe workloads to the cloud via the AWS MAP framework.
- Cloud-native microservices architecture using AWS Lambda, EKS, and Amazon DynamoDB optimization.
- Defined security guidelines (IAM/KMS) and interoperability grounded in the AWS Well-Architected Framework.
PagBank
- Led cloud audit and governance initiatives that identified and removed idle resources at scale, generating millions in direct annual savings.
- Built a Custom Terraform Provider to abstract infrastructure provisioning, removing operational bottlenecks and accelerating delivery for dozens of engineers.
- Implemented a Policy-as-Code ecosystem (Cloud Custodian) for real-time risk remediation and credential-rotation workflows integrated with HashiCorp Vault.
Transpeg
- Defined the technology roadmap and architecture of a full-stack SaaS platform, from zero to production.
- Developed routing algorithms and robust APIs aligned with logistics business goals.
- Implemented scalable AWS infrastructure and automation pipelines with a strict focus on FinOps and budget optimization.
