The brief

Launch and mature AIsensy's mobile app on both Android (Play Store) and iOS (App Store) while simultaneously migrating their backend infrastructure to a scalable Kubernetes-based architecture, and continue evolving the web platform with new feature modules to support their growing WhatsApp marketing SaaS business.

What we built

A comprehensive engineering engagement across three parallel workstreams:

  • A Flutter mobile app for WhatsApp marketing teams, featuring live chat with agent intervention, Meta Ads management with AI image generation (Ideogram), contact management with CSV import/export, campaign analytics, and multi-provider auth (Google, Apple, 2FA)
  • Web dashboard UI design and feature development spanning generative AI templates, free-plan flows, audience segmentation, affiliate management, WhatsApp Forms, popup builder, and a full dashboard revamp
  • A production-grade AWS infrastructure migration from ElasticBeanstalk to EKS Kubernetes with Karpenter + KEDA autoscaling, Prometheus/Grafana/EFK observability, Jenkins CI/CD pipelines with rollback, WAF + VPN security hardening, and multi-tenant enterprise client onboarding (Paytm, Redington, Netambit).
⊛ Live in production

Flutter mobile app published to Google Play Store and Apple App Store (v1.0.4+) with live chat, Meta Ads management, auth flows, and notification support. Production EKS cluster running across prestaging/staging/production environments with full observability, CI/CD, WAF, and VPN. Enterprise tenants (Paytm, Redington, Netambit) onboarded on dedicated infrastructure. Web dashboard continuously deployed via AWS Amplify with new feature modules shipped across the engagement.
