Executive Summary

Overview

The Capital was a social media platform combining real-time feed mechanics with long-form publishing, a follower-based social graph, and integrated monetization via micropayments. Tech Stack Playbook was engaged to re-architect the platform from the ground up.

The engagement executed a dual migration (Angular/GCP → React/AWS → Next.js/TypeScript), built Stripe Connect payment infrastructure with full KYC/AML compliance, designed the GraphQL API layer on AppSync, and delivered the platform through to its 2023 acquisition. The work was presented at the AWS NYC Summit.

The Challenge

What Needed to Change

The platform had product-market traction but was hitting the limits of its original architecture across every dimension: frontend performance, backend scalability, deployment velocity, and the ability to ship new features.

  • Monolithic Angular frontend was slow to iterate — couldn't support rapid social media product cycles
  • Google Cloud lacked the managed service ecosystem for real-time data and serverless compute
  • No server-side rendering meant poor SEO for published articles and no feed caching
  • No payment infrastructure for micropayments, creator monetization, or KYC/AML compliance
  • No content moderation or anti-spam tooling to protect from bot activity
  • Needed to execute a live re-architecture while continuing to serve the user base
What We Delivered

Full-Stack Platform Engineering

The re-architecture spanned every layer of the platform — from frontend framework to payment processing to content moderation.

DynamoDB at Scale
Schemas optimized for social media access patterns with GSIs, Streams, and fan-out Lambda functions for real-time notifications.
05
Cognito + Twitter OAuth
Custom identity provider flow federating Twitter login into Cognito sessions for seamless cross-platform SSO.
06
Content Moderation Tooling
Bot detection, spam takedown procedures, and admin tools to protect platform integrity at scale.
Key Insight
The payment infrastructure was presented at the AWS NYC Summit in 2023 as a reference implementation of Stripe Connect on AWS serverless architecture.
