Custom AI assistants
Interfaces and integrations for assistants that help with a defined task. We scope the information they can access, the responses they should produce, and what happens when a request needs human judgment.
AI & Automation Development · TopGuy
AI and automation with a clear purpose.
I’m Rehan Hamayun, founder of TopGuy in Islamabad, Pakistan. I build AI features, workflow automations, and integrations for businesses worldwide, connecting useful intelligence to the software your team already uses.
Discuss your projectBuilt around your business
Start with a task that takes too much time: moving information between tools, preparing content, or handling a repetitive workflow. We decide which steps need predictable rules, which can benefit from AI, and where a person should review the result. Not every step needs a language model.
What we can build
Workflow automation
Connect triggers and actions across business tools with n8n or custom code. Notifications, reporting, and moving data between systems are useful starting points for a focused automation project.
AI features inside your product
Add generative capabilities to an existing website or app, with an interface people can understand and controls to review the output. The AI Website Builder case study shows one application of this approach.
APIs & business integrations
Connect tools through their available APIs, with clear data mappings and error handling. We identify access requirements, usage limits, and ongoing service costs before agreeing on the implementation.
Where we start
Describe the workflow as it works today, the tools involved, how often it runs, and the result you want. A few representative examples help define a useful first version and how its output should be checked.
Budget & timeline
AI and automation projects receive a custom quote based on integrations, workflow complexity, and review requirements. Third-party API and hosting costs are discussed separately so you can understand the ongoing cost as well as the build.

AI Website Builder
An AI-powered website builder that turns prompts into launch-ready sites — custom layouts, live editing and one-click publishing, all in the browser.
Restaurant QR Ordering
A QR-code ordering platform for restaurants — guests scan, order and pay from the table while staff get realtime alerts and the whole operation runs on automations.
Before we get started
Do I need to replace the software my team already uses?
Often the goal is to connect existing tools. What is possible depends on their APIs, account permissions, and the workflow itself. We review those constraints before choosing a solution.
Can AI run the whole workflow without review?
That depends on the task and the consequences of a mistake. We define which steps can run automatically and where approval or a fallback is needed, then check the workflow against representative examples.
