Engineering a modern crypto education & social platform.
A crypto education and social platform, not an exchange or brokerage, combining community, courses, live events, research, and premium memberships.
- Rebuilt the platform on Next.js and NestJS for long-term modular scalability
- Real-time notification pipeline on Ably fanning out to web, iOS and Android
- Recurring Stripe subscriptions gating premium community and course access
Empire Crypto Trading is not an exchange or brokerage, it's an education and social platform where crypto traders learn, connect, and grow together. I joined as lead full-stack developer and product engineer to lead the platform's technical evolution for the client, with a focus on high-concurrency architecture and real-time community engagement.
The problem
Quality crypto education was scattered across YouTube, courses, threads, and PDFs with no single home. Communities were fragmented across Discord, Telegram, Facebook, and X, each holding a piece of the conversation but never the whole thing. Discovery of trustworthy content and the right people was mostly luck. The link between educators and members was weak, engagement suffered without real-time feedback loops, and paywalls, content, and community lived in separate tools that never quite connected.
The platform
The rebuilt platform brings six pieces together: a community feed where traders post, react, and discover each other; structured education with courses, lessons, and progress tracking; live events connecting educators and members in real time; premium research and market analysis; a membership platform gating premium access and digital products; and a mobile experience carrying the whole platform to members wherever they are.
Engineering challenges
- Scale. Feeds, follows, and reactions designed to stay fast and consistent as content and connections grow.
- Real-time notifications. Likes, replies, and live-event updates delivered across web and mobile through an event-driven design built on Ably.
- Secure subscriptions. Recurring billing and entitlement checks that gate premium content reliably, without adding friction for members.
- Flexible CMS. A publishing workflow that lets creators ship courses and research without engineering in the loop.
- Feature modularity. Clean module boundaries so community, education, and commerce can evolve independently.
- Production monitoring. Observability and deployment pipelines to keep a member-facing platform dependable.
My contributions
I designed the real-time notification pipeline on Ably, one event source fanning out to web and mobile with delivery behaviour the team could reason about. I implemented the Stripe subscription workflows that power premium memberships and exclusive content access, built the interactive frontend surfaces for community engagement and content discovery, and built the NestJS and PostgreSQL service layer behind clean module boundaries for auth, business logic, and integrations. I integrated Sanity CMS to give content creators a maintainable publishing workflow, and worked across deployment pipelines and production environments to improve reliability.
Technology
The frontend is Next.js, React, TypeScript, and Tailwind. The backend runs on NestJS and Node.js over REST APIs and WebSockets, backed by PostgreSQL and Redis. Infrastructure is AWS, Cloudflare, and Docker, with Stripe, Firebase, Ably, and Sanity CMS as the key integrations.
Lessons
Designing a social platform that scales starts with the data model, not the feed UI. Maintainable SaaS comes from real module boundaries, not just folders. Feature velocity and quality are a balance re-struck every sprint, and technical debt is a budget to track rather than pretend is zero. Distributed collaboration runs on written decisions and clear contracts.
