FAQ

Questions, answered.

What kind of AI agents can you build?

Conversational agents for Messenger, WhatsApp, Telegram, web and email; multi-agent systems; voice AI; RAG knowledge assistants; and full business-process automation — all self-hosted on n8n + Docker if you prefer.

Can you build any kind of software?

Yes — web apps, SaaS, dashboards, CRM/ERP and internal tools, APIs, integrations, LMS and e-commerce platforms, with AI layered in where it adds value.

Do you only work with WordPress?

WordPress is my expert platform for fast delivery, but I also build full custom applications — for example the B1 Student Portal, a multi-role LMS built with Next.js, React and PostgreSQL. I choose the stack that fits your goals and budget.

How long does a project take?

A focused automation or website can take 1–3 weeks. Custom software typically takes 4–12 weeks depending on scope. You get a clear timeline after the discovery call.

Do you work with international clients?

Yes. I currently serve clients in Bangladesh, the UK and the USA, working over WhatsApp, email and video calls across time zones.

Do you offer support after launch?

Yes — maintenance, monitoring, hosting/VPS management, security audits and continuous optimization as ongoing retainers.
