ABOUT Srayash Raj
Full-Stack developer specializing in high-throughput backend architecture, sandboxed execution engines in Go/Kubernetes, and published Flutter mobile applications.

Bridging Distributed Backend Systems & Mobile Cryptography.
I am a full-stack engineer driven by the rigor of low-level backend plumbing and the elegance of polished mobile user interfaces. Based in Hooghly, West Bengal, I study Computer Science at the Academy of Technology and lead backend engineering across critical campus initiatives.
My engineering work spans the full spectrum of modern software: from writing custom Go drivers and sandboxing untrusted code in isolated Kubernetes pods with sub-second execution limits, to architecting PostgreSQL transactional billing engines with BullMQ/Redis worker pipelines, to publishing SecuChat on the Google Play Store using ECDH end-to-end asymmetric encryption and the Flutter BLoC pattern.
I also serve as the Backend Lead for Chakravyuh (handling 1,000+ stress-tested concurrent users on PostgreSQL/Redis/Drizzle ORM), Technical Associate at InnovateX Engineers Community, and Tech Team member at AWS Cloud Club AOT where I mentor students on cloud deployments.

HOW I BUILD SYSTEMS
Clean Architecture First
Repositories are strictly decoupled from use-cases and controllers with centralized dependency injection. Business logic never depends on database or framework quirks.
Zero-Trust Sandboxing & Cryptography
Untrusted user code must be containerized with explicit cgroups, wall-time limits, and CPU throttling. Private communications must employ asymmetric ECDH encryption where keys never leave user devices.
Production Documentation & OpenAPI
APIs are only as good as their contracts. I author exhaustive OpenAPI 3.0 specs (5,500+ lines for Smile Care) ensuring frontend sync, automated testing, and zero contract drift.
Resilient Asynchronous Pipelines
Billing, PDF rendering, email, and webhooks must never block HTTP threads. BullMQ and Redis queues with exponential backoffs and concurrency limits ensure zero dropped tasks under load.
1st Prize @ TCS Tech Day & 3rd Place @ NEXHACK 2.0
Whether leading teams under sprint pressure or architecting novel messaging protocols, I build to solve real challenges with production rigor.
