- Defined and drove multi-year mobile platform strategy, aligning with company growth and React Native evolution - Co-founded Mobile Operations → Enablement, shaping how mobile engineering scales across the organization - Led RFCs, architecture reviews, and cross-team initiatives, influencing Directors and VP-level decisions - Mentored engineers (100+) across teams, raising the bar on performance, architecture, and code quality - Reduced app startup time by ~90%, improving onboarding completion and user engagement - Achieved consistent 60 FPS interactions through rendering and animation system optimizations - Improved crash-free sessions from ~80% → 99.95% across a 1M+ user base - Reduced app size from 120MB → 70MB (~40%), improving distribution and store compliance - Built CI/CD and static analysis guardrails (ESLint rules, pipeline checks) to prevent unsafe rendering and memoization patterns, eliminating entire classes of performance regressions before reaching production. - Built CI/CD systems and guardrails preventing performance regressions before production - Reduced build times (~60 → ~20 minutes) and merge time (days → ~10 minutes) - Established org-wide standards for dependency management, modularization, React memoization and code quality - Increased release frequency from every 2 months to bi-weekly, enabling faster experimentation, improving user throughput, and reducing mobile-specific production bugs - Built AI PR review agent processing ~100 PRs/day, adopted across teams and repositories - Defined AI usage patterns (Copilot, Cursor, Claude) aligned with architecture and design systems - Created internal AI tooling for project management, generating 200+ structured Jira tickets in minutes - Designed services for onboarding and video visit scheduling - Improved API reliability, error handling, and service orchestration across mobile-backend systems - Created stress and performance testing to yearly evaluate the scalability of the services

- Built real-time financial analytics web application used by institutional clients, supporting production trading decisions. - Designed high-throughput WebSocket pipeline to stream global market data in real time, handling high-frequency event streams during trading sessions. - Reduced custom index generation time from hours to 5–10 minutes (~90% improvement), enabling near real-time analytics. - Implemented distributed data ingestion pipeline (RabbitMQ) to process large-scale financial datasets reliably under load. - Introduced payload compression, backpressure handling, and optimized data structures to maintain system stability at scale. - Delivered reporting/export system for index data, supporting enterprise client workflows and stakeholder requirements. - Delivered performance-critical features that contributed to acquiring and retaining enterprise banking clients - Designed data models, APIs, and reporting systems for financial analytics workflows Implemented compression, backpressure, and payload optimization for stability at scale

As a semi-senior developer at HexaSystem, I played a crucial role in developing a social network app tailored to artists. This app provides a platform for artists to showcase their works through cards containing photos/videos, along with comprehensive information such as event calendars, location via Google Maps, and informative documents. My responsibilities encompassed translating mockups from inVision into ReactNative components, managing TestFlight/Apple Store credentials, bug fixing, and seamless integration with native phone components. I also conducted unit tests using Jest and Enzyme and integrated various services/APIs to enhance functionality. Leveraged technologies/libraries include ReactNative, Redux/Saga, Google Maps APIs, and multimedia and document management libraries.

Developed and launched Mercantil Tpago, one of Venezuela’s most-used mobile payment apps, driving widespread adoption by focusing on ease-of-use, security, and rapid iteration. Built microservices to support scalable and maintainable backend infrastructure, integrating seamlessly with external banking APIs and third-party services. Oversaw full release lifecycle from CI to store submission, managing TestFlight configurations and ensuring delivery across multiple platforms under tight regulatory and timeline constraints. Contributed to cross-team initiatives to standardize reusable components, reduce duplication, and align development practices across teams.
