Work History
Senior Systems Engineer (AI & Data Platforms)
FourKites, Inc.
United States (Remote)
06.2025 - Current
- Engineered an event-driven data ingestion pipeline in Pipedream using REST APIs and LLM-based PDF parsing, fully replacing a manual CSV process, eliminating carrier involvement, and significantly reducing data onboarding time.
- Designed deterministic LLM extraction pipelines with validation and data merging, improving tariff data accuracy and eliminating recurring inconsistencies in complex regional pricing rules.
- Upgraded Go and Ruby backend services to support an extended MongoDB tariff data model, enabling downstream systems to leverage the new structure.
AI Model Alignment & Evaluation Engineer
Scale AI
United States (Hourly Remote Contract)
03.2024 - Current
- Produced high-quality training and benchmark data for frontier LLMs using RLHF, SFT, adversarial red-teaming, and agentic tool-learning techniques, generating ground-truth responses and consistently achieving 90%+ acceptance rates.
- Promoted to trusted reviewer on multiple long-term projects, ensuring quality, consistency, and alignment across complex, multi-step contributions from hundreds of annotators.
- Debugged and enhanced LLM-generated code in 10+ languages (Python, Go, Rust, C/C++, C#, Java), serving as a cross-functional technical resource.
Platform Engineer (Backend Systems)
Hologram Sciences
United States (Remote)
01.2022 - 01.2023
- Extended an AWS-based microservices platform (Java/Kotlin, Spring Boot, PostgreSQL, Redis, Elasticsearch), integrating health monitoring devices and expanding real-time data metrics for thousands of users.
- Led a Java-to-Kotlin migration of core business logic, reducing bugs and improving long-term maintainability.
- Upgraded test infrastructure to JUnit 5 with parameterized testing, increasing code coverage and reducing debugging time across services.
Lead Software Engineer (Systems & Architecture)
IPremios
Rio De Janeiro, Brazil
2017 - 2022
- Served as the primary technical escalation point across multiple backend stacks (Groovy on Rails, Java, Python), unblocking teams and resolving critical cross-service issues.
- Designed a scalable microservices REST backend (Kafka, Micronaut, Docker, Kubernetes) following DDD principles, enabling strong service decoupling and long-term evolvability across loyalty and workforce management platforms.
- Built an offline-first mobile framework using Couchbase background synchronization, maintaining a seamless UX during extended connectivity loss across hybrid (Ionic, Angular, NativeScript) and native Android (Kotlin) apps.
- Designed and implemented a computer vision ML pipeline (Node.js, Amazon Rekognition, SageMaker Ground Truth) for automated image classification and model retraining.
Lead Software Engineer (Architect)
Telarix
United States (Remote)
2007 - 2017
- Promoted from junior to lead engineer in under two years, becoming a technical reference for a team of 10+.
- Designed, from scratch, and owned a high-throughput, template-driven document ingestion engine, enabling the onboarding of 300+ carriers ahead of a 2-year target.
- Architected a DDD-based SOA and evolved it into a distributed microservices model, enabling a seamless migration to Azure around 2015. The platform now processes 1.5 million documents per year.
- Replaced VBA-based Excel preprocessing with a C# runtime solution, reducing maintenance time from hours to minutes.
