Harold Dagadu

Harold is a high-leverage technical operator who converts ambiguity, setbacks, and operational friction into structured systems that scale. He holds a First-Class Software Engineering degree and has hands-on experience across React, TypeScript, C, SQL Server, Docker, n8n, Next.js, authentication frameworks, and DevOps. His defining psychological signature is turning adversity into compounding capability: overcoming health challenges and an education pause to return to university and graduate at the top of his class. This resilience-to-reflection-to-rapid-adaptation identity makes him exceptionally effective in early-stage, high-pressure startup environments—he doesn’t break under pressure, becomes sharper, and metabolizes hard tasks into frameworks that elevate the team’s baseline.

Harold exemplifies founder-worthy execution, demonstrated by his rapid build of a fully automated content-generation pipeline despite zero prior n8n experience. Within Mary’s fulfillment ecosystem—which spans manufacturing, logistics, PAT deployment, customer onboarding, ticketing, agent workflows, and client communications—he functions as a technical orchestrator ensuring the last mile works flawlessly. He engineers reliability through React and Tailwind frontends, C/.NET backend integrations, SQL schemas, JWT authentication, and automated development workflows designed for predictability. He automates repetitive friction using n8n, Docker, webhooks, and OpenAI-powered automation, ensuring a seamless end-to-end customer journey whether for B2B hospital PAT orders, DTC individual device purchases, or B2B2C clinic-on-behalf-of-patients. His work makes fulfillment fast, accurate, transparent, trackable, and extendable as Mary scales.
