Prakasam
Hello!

I'm Prakasam Mathaiyan

— Lead Product Designer.

I'm a Bangalore-based Lead Product Designer with 14+ years of experience shaping experiences across consumer and enterprise products. I specialize in AI conversation design — crafting natural, trust-building interactions between humans and intelligent systems.

I design for AI — exploring the UX of AI-powered products, intelligent interfaces, and conversational experiences. I also design with AI — using AI as an augmented design partner to accelerate research, ideation, prototyping, and delivery.

Across everything I do, accessibility is foundational — ensuring every experience works for everyone, not as an afterthought but by design. I also bring front-end development skills (HTML, CSS, JavaScript) to rapidly prototype ideas and validate design decisions in code.

Expertise

Core capabilities I bring to every product and team I work with.

  • Product Design

    End-to-end product thinking — from discovery through delivery, shaping experiences that balance user needs with business outcomes.

  • AI & Conversational UX

    Designing natural interactions between humans and AI — chat interfaces, intent flows, trust patterns, and progressive disclosure for intelligent systems.

  • UI & Interaction Design

    From wireframes to polished interfaces — crafting visual systems, micro-interactions, and responsive layouts that feel intuitive at every breakpoint.

  • Design Systems

    Building and governing scalable component libraries, token architectures, and documentation that unify teams and accelerate delivery.

  • Accessibility

    WCAG-driven inclusive design — semantic markup, screen reader testing, keyboard navigation, and contrast compliance baked into every decision.

  • User Research & Testing

    Qualitative and quantitative methods — interviews, usability testing, analytics review, and rapid iteration based on real user behaviour.

  • Front-End Prototyping

    HTML, CSS, SCSS, JavaScript — building functional prototypes that validate design decisions in the browser, not just in Figma.

  • Design Leadership
