Marcelo Marleta

• • Architected and maintained multi-tenant microservice platforms using FastAPI, async workers, PostgreSQL, and Redis, ensuring strict tenant isolation and predictable behavior under concurrency.

• • Built secure platform foundations including RBAC-style access control, rate limiting, audit-friendly logging, and deterministic data-access patterns.

• • Designed state-machine–driven workflows with explicit transition validation, idempotency, and safe recovery mechanisms for complex operational flows.

• • Owned systems end-to-end: architectural decisions, implementation, deployment, monitoring, and incident response.

• • Implemented observability pipelines with OpenTelemetry to improve traceability, latency analysis, and faster production debugging.

• • Built platform guardrails and validation layers around probabilistic systems, focusing on auditability, predictability, and safe production usage.

• • Worked directly with stakeholders and end users to translate messy, real-world requirements into opinionated, scalable platform capabilities.

• • Deployed and operated services in production environments, handling upgrades, operational issues, and reliability improvements.

• • Developed embedded and mobile software in C/C++ for constrained hardware platforms.

• • Led protocol development efforts for LG's mobile division in Latin America.

• • Built a strong foundation in low-level systems, debugging, and disciplined engineering under strict constraints.

• • Operating Systems (Linux, system calls, C)

• • Concurrent Programming (MPI, OpenMP)

• • Digital Logic & FPGA (VHDL)
