The team

What the team covers

Since 2026 this is a company, not a freelancer: three developers, a designer and three SEO specialists in the Kolkata, India office, plus around six people working remotely. Here is what that buys you — I still lead every project.
  • Design

    Wireframes and Figma mock-ups before any build, with pages that stay consistent with your brand.
