    Communication with Karim was clear and responsive throughout the whole project, and he made sure expectations around the HubSpot integration and dashboard scope were well defined from the start. Any questions I had were handled quickly, and the final build came out exactly as discussed.

    Worked with Karim on a strategy session for a B2C web app and he came prepared with a structured approach covering feature scoping, stack selection, and product positioning for a consumer-facing audience. Would work with him again without hesitation.
