About Mostafizur Rahman

Who I am

I am an AI builder and Gen AI engineer based in Kushtia, Bangladesh. I build AI-powered web apps, SaaS MVPs and n8n, Zapier and Make.com automations for remote teams in the USA, UK and EU, and I have worked remotely for US companies since 2021.

What I do

I turn manual, messy work into software that runs. That means three kinds of projects: automations in n8n, Zapier and Make.com with AI steps inside them, AI-powered web apps and SaaS MVPs built with AI-assisted development, and the SEO, social media and lead generation work that brings people to them.

Two examples you can try: SignPro, a legally binding e-signature platform, and SociPRO, an autonomous social media agent. Both have live demos and public source code.

How I got here

I started working remotely in 2021 as a virtual assistant for Frontier, a recruitment platform in San Francisco. Over the next four years I worked in market research, social media, SEO content and lead generation for US companies. In 2024 I improved organic search rankings by 25% at ICMG LLC, and in 2025 I grew qualified leads by 15% at Digital Gregg.

In August 2025 I joined Artech Digital, a US company founded by an ex-Google engineer, as a Virtual Assistant and was promoted to Junior Full Stack Developer & Executive Assistant. There I build web apps, SaaS products and automations, and integrate Claude and other LLMs into the team's workflows.

How I work

I build with AI-assisted development (Claude Code and Cursor) because it lets one person ship what used to need a team. Every project still follows the same four steps, Discover, Design, Build and Launch, with clear milestones and regular check-ins. Every build is tested on real data and handed over with documentation.
