SERVICES

My awesome
services

Businesses don't need more AI hype. They need someone who makes AI pay. I combine AI-assisted development with Google-certified prompt engineering to turn ideas into software that runs.

One hire, end to end: automation, full-stack builds, marketing and design. Lean teams and startups get one person who owns the project and thinks about your profit, not just the code.

FAQ

Questions clients ask

Straight answers about how I work, the tools I use and how to hire me.

Who is Mostafizur Rahman?

Mostafizur Rahman is a freelance AI builder and Gen AI engineer based in Kushtia, Bangladesh (GitHub: msajeeb003). He builds AI-powered web apps, SaaS MVPs, AI agents and n8n, Zapier and Make.com automations for remote teams in the USA, UK and EU, and works as a Junior Full Stack Developer & Executive Assistant at Artech Digital. His projects include SignPro, SociPRO and EurekaEDU.

What does an AI builder do?

An AI builder turns an idea or a manual process into working software that uses AI. For me that means two kinds of projects: automations in n8n, Zapier and Make.com with AI steps inside them, and full web apps such as SignPro, an e-signature platform, and SociPRO, an autonomous social media agent.

How do I hire a gen AI engineer?

Describe the problem you want solved and the result you expect, then talk to the engineer about how they would measure success. To work with me, send your project details through the contact page, email mostafizur.contacts@gmail.com, or hire me on Upwork or Fiverr. Every project starts with a discovery call to agree the goal and the metric. For a checklist, read how to find the best AI developer in Bangladesh.

Do you work with clients in the USA, UK and EU?

Yes. I'm based in Kushtia, Bangladesh, and I have worked remotely with US companies since 2021, across US time zones, in English (C1). I'm open to remote projects worldwide and to relocating to the EU. Read how hiring an AI developer in Bangladesh works.

What is vibe coding, and do you use it for client work?

Vibe coding means building software by describing what you want to an AI coding assistant and iterating on what it writes. I use Claude Code and Cursor this way because it lets one person ship what used to need a team. Every build still goes through the same steps as hand-written code: it is tested on real data and handed over with documentation.

Which automation and AI tools do you use?

For automation: n8n, Zapier and Make.com, plus direct API integrations. For AI: Claude and Google Gemini. For apps: React, Node.js, PostgreSQL and Supabase. For growth work: HubSpot, Apollo.io, LinkedIn Sales Navigator and WordPress. See all services, or how the three automation platforms compare in n8n vs Zapier vs Make.com for AI lead qualification.

Can you build a SaaS MVP with AI?

Yes. I build SaaS MVPs end to end, from idea to launched product. SignPro (React, Node.js, PostgreSQL) and SociPRO (Node.js, Google Gemini, Supabase) are two examples with live demos and public code. Read more on AI app and SaaS development.

What does a project with you look like?

Four steps with clear milestones and regular check-ins: Discover (goals and the metric we measure), Design (workflow map, tools and visual direction), Build (tested on real data, with handover docs) and Launch (go-live, measurement and a plan for the next iteration).
