Hire a senior full-stack engineer who builds and runs your product
I'm Nazmul Khalid, a lead software engineer with 10+ years of experience. I work remotely with founders and businesses worldwide to build SaaS platforms, MVPs and mobile apps, then deploy and run them in production. Recent work includes DocBee, a telemedicine platform with Patient and Doctor apps, and Bicitra EMS, a multi-tenant school management SaaS.
