Arpit Sahu

🚀 Backend-focused engineer building resilient, well-modeled architectures with Spring Boot & distributed systems.
Open to Backend / Full-Stack Software Engineering Internships.

🧭 About Me & Engineering Philosophy

☕ Backend-First Mindset: I specialize in Java 21 and the Spring Boot ecosystem, focusing on robust authentication mechanisms (OAuth2, JWT, RBAC), clean relational modeling (Hibernate/JPA), and production-grade REST APIs.
🏗️ Distributed Systems Evolution: Currently decomposing monolithic Spring applications into microservices leveraging Spring Cloud Gateway, Eureka Discovery, Resilience4j Circuit Breakers, and Apache Kafka.
✦ AI-Native Engineering: Building practical LLM pipelines with Spring AI (ChatClient, Ollama local models, and RAG architectures) to automate code analysis and spaced recall drills.
🎨 Full-Stack Competency: When the mission requires a UI, I build server-rendered, accessible frontends using Thymeleaf, Tailwind CSS, and Flowbite, as well as component-driven apps with React.

🚀 Featured Architectural Builds

✦ Dev Tracker // Tactical Command Center

An automated algorithmic practice and spaced recall OS designed to eliminate the interview forgetting curve.

AI Revision Intelligence: Integrated Spring AI + Ollama (Qwen) for asymptotic complexity verification (O(N)), edge-case warnings, and active recall self-quizzes.
Smart Ingestion: Sub-50ms URL auto-detection across LeetCode, Codeforces, GFG, CodeChef, and HackerRank.
Security: Spring Security 6 with Google & GitHub OAuth2 social login.
Frontend: Zero-flash tactical dark-mode dashboard with Windster-style progress ring gauges and Tailwind CSS.

🛡️ Smart Contact Manager 2.0 (SCM)

An enterprise-ready contact management suite engineered with production-grade security and containerization.

Zero-Trust Security: Multi-provider OAuth2 (Google & GitHub), BCrypt credential hashing, and custom Role-Based Access Control (RBAC).
Containerized Deployment: Multi-stage Docker build running alongside an orchestrated MySQL service via Docker Compose.
Microservices Capstone: Currently undergoing decomposition into standalone services via Eureka Service Registry, Spring Cloud Gateway, and Resilience4j.
