I build systems
that scale.
Krrish Kumar builds distributed systems, real-time architectures & AI-powered products. Founder of Parivar AI & Ashvi Health.
About Me
I'm a backend-first engineer who obsesses over distributed systems, real-time architectures, and building products that work at scale from Day 1.
At 22, I'm building two AI startups: Parivar AI (emotionally intelligent AI for Indian families, live on web & Play Store) and Ashvi Health (AI-powered preventive health intelligence), while completing my B.Tech in Computer Science at AKGEC, Ghaziabad.
If it can't handle 10x traffic tomorrow, it shouldn't ship today.
How I Build
Four rules that decide how I design systems, from the first schema to the 3am page.
- Latency is a feature.
- Every millisecond compounds across a request fan-out, so I budget it per hop and defend that budget in code review.
- Design for failure.
- Dependencies time out and networks partition, so services degrade in tiers with backoff, retries, and circuit breakers rather than hope.
- Measure before optimizing.
- A p99 trace settles arguments that opinions cannot, so I instrument the hot path first and let the numbers choose the work.
- Build for the next 10x.
- If a system cannot absorb ten times its load tomorrow, it is not ready today, so I size for headroom before I cut capacity.

Featured Projects
Backend systems engineered for scale, resilience, and real-world production traffic.
RideWave
FeaturedBuiltReal-Time Ride Matching System
Event-driven real-time matching engine with WebSocket-based live tracking. Redis geospatial queries (Haversine) for instant driver-passenger proximity detection. Reduced matching latency by 65%.
Airline Booking
BuiltMicroservices Architecture
4 independent microservices (Auth, Booking, Search, Notification) with API Gateway, async messaging via RabbitMQ, and circuit-breaker fault tolerance.
AlgoForge
BuiltDistributed Coding Platform
LeetCode-style backend with Problem, Submission, Evaluator & WebSocket services. Code runs in isolated Docker containers via BullMQ + Redis async job pipeline.
Ventures
Beyond engineering: building products from zero to one, solving real problems for real people.
