Hi, I'm Yuvraj.
Backend and Systems Engineer.
Founding Engineer at ContextJet.ai.
What I build
Backend and Platform Systems
Designing APIs, data models, concurrency-safe services, authentication flows, and scalable backend architecture using Go, PostgreSQL, Redis, and cloud infrastructure.
Fullstack Web Systems
End-to-end systems using React, Next.js, TypeScript with backend-first design, focusing on correctness, performance, and maintainability.
AI Powered Applications
LLM-driven workflows, LangChain and LangGraph agents, automation pipelines, and AI-assisted backend services.
Selected builds
Kubernetes Core Repository Contribution
Contributed to Kubernetes core repository with focus on resource quantity parsing, numeric boundary handling, and overflow safety in apimachinery. Investigated edge cases, proposed correctness improvements, added unit tests, and participated in API-level discussions.
Role: systems programming, open source contribution, testing
Desktop Analytics Platform with Custom Authentication
Designed and built Flask and PostgreSQL backend powering a desktop analytics platform. Implemented Redis-backed refresh token system, session management, and secure authentication used by an Electron-based client.
Role: backend architecture, authentication, systems design
E-commerce Data Pipeline for Market Intelligence
Built resilient data ingestion pipeline scraping multiple external sources with fallback logic to handle rate limits and failures. Ensured consistent data availability under unreliable upstream conditions.
