I'm Marcus Alex-Ivan Howard, a backend engineer with a decade of experience designing, building, and operating production systems that process real-world data reliably at scale. I focus on data collection and processing systems, event-driven architectures, and cloud infrastructure, and I own services end-to-end—from design and implementation to deployment, monitoring, and iteration. I have worked in highly regulated and correctness-critical domains, including financial services, environmental data, and public-sector reporting, always aiming for clarity, robustness, and long-term maintainability. In leadership and individual contributor roles, I’ve built data pipelines, designed schemas for both relational and graph databases, and led cross-functional collaborations with product and frontend teams in agile, remote environments. I value auditability, reproducibility, and transparent analysis, prioritizing pragmatic engineering that stands up to real-world use while remaining adaptable for future requirements.
