Engineering a wellness platform at national scale
Habuild isn’t just a wellness brand, it’s a movement.

RabbitMQ
With millions of users participating in daily yoga sessions over WhatsApp and live streams, Habuild operates at a scale rarely seen in consumer wellness. Their mission is simple but ambitious: build healthy habits for India, every single day.
Habuild needed a technology partner that could help them re-architect their systems for reliability, speed, and scale, without slowing down their momentum.
The challenge
That scale brought unique engineering challenges:
Supporting crores of real-time messages during mass yoga events
Handling hundreds of thousands of concurrent participants
Ensuring zero downtime during national record attempts
Migrating and stabilizing legacy infrastructure for future growth
Building a backend that could scale from community-led WhatsApp groups to a full-fledged digital platform
That’s where Proximity came in.
What We Built
We partnered with Habuild to design and engineer a high-throughput, event-ready platform that could reliably support the world’s largest digital yoga community.
Our work focused on three pillars:
01
Infrastructure at national scale
We helped modernize Habuild’s backend architecture to make it resilient, fast, and future-ready.
- Migrated core databases from PlanetScale to PostgreSQL across services
- Introduced consistent seeders and environment parity across systems
- Re-architected Redis for member persistence and high-volume lookups
- Deployed and optimized workloads on AWS + Kubernetes + Cloudflare
02
High-Volume messaging engine
Habuild’s magic happens through messaging daily nudges, reminders, class links, and community prompts. During national events, the system must deliver crores of messages in minutes.
What we did:
- Refactored the RabbitMQ pipeline for high-throughput scheduling
- Improved RabbitMQ connectivity for resilient message handling
- Optimized consumer logic using batch-based Redis lookups
- Built safeguards for retries, failures, and rate-limiting
- Coordinated large-scale load testing and Kafka debugging
The Result
1.5 crore messages delivered in under 50 minutes, reliably.
03
Platform expansion & product enablement
As Habuild evolved beyond WhatsApp into a multi-platform ecosystem, we helped shape the next phase of their product:
- Built APIs for attendance tracking and program routing
- Designed endpoints for manual and automated message triggers
- Added authorization layers for subscriptions and member access
- Created internal tooling and API documentation for rapid iteration
- Supported the Habit Portal experience for coaches and admins
Impact
Habuild today is not just a startup, it’s a national infrastructure for wellness.
With Proximity’s engineering partnership, Habuild has:
20+ lakh
Enabled yoga sessions for 20+ lakh people
5,99,162
Supported events with 5,99,162 participants in a single day
2,46,252
Set world record with 2,46,252 people in a single live event
Built a backend capable of handling crores of real-time interactions
Laid the foundation for global expansion beyond India
Habuild’s world records are not just about participation, they are about engineering at human scale.
Why It Matters
Most systems are built for users. Habuild is built for a nation.
This project pushed us to rethink:
- What “scale” truly means in consumer tech
- How infrastructure supports emotional moments at mass scale
- How engineering enables culture, habit, and human change
At Proximity, we don’t just build softwares, we build systems that carry belief.
Habuild is one of those systems.
