I resolve SaaS, email, DNS, and Google Workspace issues for remote client teams.
LebanonWhat I'm looking for
At Markarie, I resolved 30–60 technical issues each week for 15+ client accounts across SaaS platforms, email systems, DNS, hosting, and end-user devices.
I was promoted twice in 14 months, progressing from R&D and Technical Support Intern to Junior Specialist and then Technical Support and R&D Specialist while supporting a US-based team remotely. I configured and verified SPF, DKIM, and DMARC records, administered Google Workspace, and monitored websites, domains, and IP reputations to maintain availability.
I also designed and deployed 50+ custom HTML email signatures and documented recurring issues to reduce repeat tickets and manual work through automation.
Alongside support work, I'm building a full-stack e-commerce storefront with Next.js, TypeScript, Prisma, and Tailwind CSS, including an authenticated admin dashboard, inventory management, order processing, transactional email, webhooks, and bot protection. I also support Lebanese Red Cross operations through data validation, user support, logistics, and disaster-response coordination.
