Two decades architecting resilient software systems. Helping organizations deploy sovereign, local AI—self-hosted on-premise or in private clouds with complete data confidentiality—and delivering high-scale mobile solutioning across Android, iOS, and Flutter for tens of millions of users. Consulting delivered via Keypad DS (est. 2013).
Engagements delivered as principal consultant, technical lead, or via specialized contracting networks.
High-stakes architectural challenges resolved with focus on production stability, legacy modernization, and tangible business outcomes.
Modernized an eleven-year-old codebase to Jetpack Compose and Clean MVVM with Use Cases while sustaining near-zero crash rates across massive daily active audiences. Architected the complete in-app purchase flow contributing to a seven-figure annual recurring revenue stream.
Supported critical integration efforts for the Disney+ merger, ensuring infrastructure readiness for high-concurrency international streaming. Led playback architecture migration to MVVM with ExoPlayer, resolved production Parental Controls, and enhanced automated test coverage.
Contributed to Brazil's premier streaming platform from initial R&D to nationwide scale serving tens of millions of monthly viewers. Architected multi-camera live streaming for flagship events, DRM-protected video pipelines, and resilient offline download playback.
Engineered a robust offline-first architecture supporting multi-day field sales operations with zero data loss. Integrated machine learning persona scoring models that substantially improved field conversion accuracy and delivered seven-figure business impact.
Managed multi-platform engineering squads across Web, Android, and iOS driving global distribution and logistics initiatives. Spearheaded cross-platform solutioning including Flutter/Dart and native mobile architectures, championed on-device computer vision and predictive stocking, and restructured CI/CD pipelines to cut release cycle times by more than half.
Restructured mission-critical systems and networking infrastructure for one of Brazil's foremost asset management firms managing multi-billion portfolios. Slashed disaster recovery time from days to two hours while maintaining a 100% operational uptime track record.
Private, sovereign AI infrastructure for confidential enterprise workflows, paired with senior mobile solutioning across Android, iOS, and Flutter.
Deploy state-of-the-art open-weights models (Llama 3, DeepSeek, Mistral) on dedicated local hardware or isolated private cloud VPCs. Zero external network calls, zero public telemetry, and full operational sovereignty.
Proprietary intellectual property, internal financial records, contracts, and customer data remain strictly within your perimeter. Never routed to OpenAI, Anthropic, or third-party cloud APIs.
Eliminate volatile per-token API charges, usage rate caps, and recurring per-seat SaaS subscriptions. Run unlimited internal queries and continuous batch workloads on predictable, owned infrastructure.
Air-gapped Retrieval-Augmented Generation (RAG) and intelligent workflow agents indexing your internal databases and documents—delivering hallucination-resistant semantic search and automation without cloud exposure.
Full-spectrum mobile engineering spanning native Android (Kotlin, Jetpack Compose), iOS, and Flutter/Dart. Combining cross-platform rapid iteration with deep native hardware performance.
Staff-level leadership managing multi-disciplinary engineering squads across Web, Android, and iOS (as delivered at AB InBev and Globo). Standardizing Clean Architecture, establishing CI/CD pipelines, and mentoring senior teams.
Battle-tested architectures for low-latency playback (ExoPlayer), DRM protection, background sync, and resilient offline-first persistence engineered for tens of millions of concurrent viewers.
Implementing Google Play Billing, StoreKit, Adapty, and subscription lifecycles engineered to safeguard seven-figure ARR while sustaining near-zero crash rates across high-volume releases.
All advisory and consulting contracts are formally invoiced through Keypad DS (KDS Desenvolvimento de Software LTDA), an established Brazilian software consultancy operating continuously since 2013.
My engineering career spans the full evolution of modern software. I began architecting distributed conferencing systems serving hundreds of thousands of users at IBM, managed mission-critical financial infrastructure for multi-billion asset managers at IP Capital Partners, and built early probabilistic machine learning engines in 2004.
Over the last decade, I led multi-platform mobile solutioning—managing cross-functional squads across Web, Android, and iOS at global enterprises like AB InBev, architecting native mobile and Flutter/Dart systems, building Globoplay from initial R&D into a national streaming platform serving tens of millions of viewers, and modernizing long-standing production codebases at Zello and Disney+.
As a former guest lecturer in mobile architecture at the Federal University of Rio de Janeiro (UFRJ), I emphasize code cleanliness, systematic testing, and pragmatic business value. Today, through Keypad DS, I specialize in deploying sovereign, local AI systems—self-hosted on-premise or in private clouds with complete data sovereignty—paired with staff-level mobile solutioning across Android, iOS, and Flutter.
Whether you want to implement sovereign, local AI self-hosted on your own hardware or private clouds, or need staff-level mobile solutioning across Android, iOS, and Flutter, let's discuss your roadmap.
