Summary Full-stack architect with 16+ years of experience designing and scaling distributed systems across AdTech, payments, IoT, and real-time platforms. I design end-to-end system architectures, covering backend services, data systems, and user-facing applications, ensuring platforms scale from MVP to production. My work spans high-throughput systems, event-driven architectures, and data-intensive platforms. I’ve built and architected systems such as AdTech platforms (SSP, DSP, Ad Servers), payment workflows, dashboards, and real-time data pipelines, including a recent DOOH AdTech MVP covering inventory modeling, campaign workflows, delivery, reporting, and UI-driven operations. I’m particularly strong in working with complex or undocumented systems - quickly understanding architecture, identifying failure points, and stabilizing them with clean, long-term solutions. Core strengths include distributed systems, system design, data consistency, performance under high load, and aligning backend architecture with product and user workflows. If you need ownership across the full stack, from system design to scalable implementation, I can help.
