Pre-final year student shipping production-grade distributed systems, real-time applications, and scalable backend architectures.
The Engineer
Pre-final year engineering student and backend-focused developer with hands-on production experience building distributed systems and scalable architectures. Currently engineering at Radiant Horizon Hospitality while shipping real-world systems that serve live users. My approach is rooted in the belief that software should be as durable as physical infrastructure.
Philosophy
Scalability is not an afterthought; it is the foundation of the architecture.
Reliability over hype. Boring technology is often the most robust.
Code is read more than it is written. Precision in naming and structure.
Engineering Scalable Systems.
Backend & Systems
JavaScript / TypeScript
Node.js / Express
React / Next.js

K8s
Infrastructure as Code: Terraform, CI/CD Pipelines (GitHub Actions, Jenkins), AWS EC2 / S3 / Lambda
Systems Architecture
Visualizing high-concurrency patterns and distributed infrastructure modules designed for resilience.
Event-Driven Monitoring
Real-time ingestion and telemetry processing pipeline.
Queue-Based API Logic
Asynchronous task management and load balancing.
Edge Proxy (NGINX/Envoy)
Global distribution and TLS termination at the edge.
ENGINEERED
SOLUTIONS.
Technical showcase of high-performance systems, distributed architecture, and immersive digital environments.
RelayEdge
Asynchronous reverse proxy built with Node.js. Engineered a custom hybrid caching layer (in-memory L1 + disk L2) for extreme throughput with minimal latency overhead.
Sentinel
Advanced VM monitoring platform. Utilizes a Node.js-based agent, Redis Streams for message bus, and ClickHouse for OLAP analytics.
API Monitor — Real-time Health Platform
Built a full-stack, event-driven API monitoring platform using a scalable queue-based architecture for real-time uptime/latency tracking and fault isolation.
Key Features
- Real-time dashboard
- Instant email alerts (Mailjet)
- Asynchronous health checks
Tech Stack
VR-Connect
2D Virtual Space with WebRTC spatial audio integration. Real-time communication via WebSockets and PostgreSQL persistence.
Hobostays Network
A full-stack hospitality infrastructure comprising three critical platforms for property management and data extraction.
