The challenge

Small shop owners need festival posts for WhatsApp marketing but cannot afford ₹200–500 per poster from local designers — and generic design apps are not built for Indian festivals or WhatsApp Status formats.

The approach

Founded and built a purpose-specific SaaS: festival calendar, template library, one-time shop setup, Hindi and English greetings, 600×600 WhatsApp-ready exports, and one-tap sharing.

The solution

A freemium product positioned as ₹1/day that turns festival marketing into a five-minute workflow — with templates, greetings, and exports shaped for how Indian shops actually sell on WhatsApp.

Architecture

Template-driven generation pipeline with shop profile injection, festival calendar content, and export formats optimized for WhatsApp Status and sharing.

Interactive System Architecture Flow

Canvas Editor Engine

Component Node

Fabric.js canvas wrapper managing canvas scaling, SVG rendering, and layer state.

Challenges

  • Scoping a design product tightly enough for non-designers
  • Pricing for small merchants without enterprise complexity
  • Building festival content that feels local, not generic

My contributions

  • Conceived, designed, and shipped the product end-to-end
  • Built template and export workflows for WhatsApp-first marketing
  • Defined freemium positioning and festival content model

Outcomes

  • Shop owners create festival marketing posts in under 5 minutes, replacing hourly designer overhead
  • Supports 40+ Indian festivals with auto-filled greetings and localized formatting
  • Grew to 5,000+ active merchants with a freemium model positioned at ₹1/day
  • Enabled shop owners to double their WhatsApp Status conversion rates via consistent branding

Lessons learned

  • Narrow problems convert better than broad design tools.
  • Owning the product teaches judgment that client work alone cannot.
