About
👋 Hi, I’m Sourav — a Senior Lead Software Developer with 12+ years of software engineering experience, specializing in scalable, resilient, event-driven, and distributed backend systems.
I help software engineers crack coding & system design interviews, transition into strong backend roles, and grow their careers through practical, hands-on mentorship.
🎯 **What I Can Help You With**
▪️ **System Design (HLD + LLD)** — Learn how to approach real-world architecture problems like a senior engineer.
▪️ **DSA & Coding Interviews** — Structured problem-solving, algorithms, complexity analysis, and LeetCode-style preparation.
▪️ **Backend Engineering** — Java, Spring Boot, microservices, APIs, databases, caching, messaging, and distributed systems.
▪️ **Distributed Systems** — Scalability, availability, fault tolerance, concurrency, consistency, and performance.
▪️ **Event-Driven Architecture** — Kafka, asynchronous processing, messaging, and event-driven microservices.
▪️ **AI & LLM Applications** — LLM fundamentals, RAG, LangChain, LangGraph, embeddings, vector databases, and AI-powered backend applications.
▪️ **Mock Interviews** — Coding, backend, HLD, LLD, and system design with actionable feedback.
▪️ **Career & Resume Guidance** — Resume reviews, interview preparation, career roadmaps, and guidance for developers starting or switching careers.
🏗️ **Architecture & Distributed Systems**
▪️ Microservices & Orchestrator Architecture
▪️ SAGA, CQRS, Event Sourcing, Outbox, Sidecar & Materialized View patterns
▪️ Distributed systems, scalability, resilience, fault tolerance & eventual consistency
▪️ Event-driven architecture using Kafka for high-throughput, loosely coupled communication
▪️ REST, gRPC, GraphQL, WebSocket & SOAP API design
▪️ Caching, load balancing, database optimization & performance engineering
▪️ Resilience patterns — retries, circuit breakers, idempotency, fault isolation & graceful degradation
🤖 **AI & Modern Backend Engineering**
▪️ LLM & AI application architecture
▪️ Retrieval-Augmented Generation (RAG)
▪️ LangChain & LangGraph
▪️ Embeddings & Vector Databases
▪️ Integrating LLMs with backend and microservices
▪️ Designing scalable, production-ready AI applications
💻 **Tech Stack**
Java | Spring Boot | Kafka | Redis | MySQL | Cassandra | Docker | Kubernetes | AWS/Cloud | CI/CD | REST | gRPC | GraphQL | LLMs | RAG | LangChain | LangGraph
🧠 **My Mentorship Style**

Sourav is an exceptional mentor who is deeply familiar with the tech stacks used by top companies. We reviewed my CV multiple times, and he always provided insightful, actionable feedback. We also worked through LeetCode-style problems to identify my weak points during interview prep, and he gave great advice on which types of questions I should focus on practicing more. I would highly recommend him as a mentor.

What happens when you start
You tell Sourav your goals. They see exactly what you want to work on before session one.
You meet within days. Sourav reviews your application and books your first session, usually within a day or two.
You leave with a plan. Concrete next steps and a weekly rhythm from your very first week.
