Your mentor

👋 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

Frequently asked questions

What exactly is a session?

A session is a focused one-on-one call with your mentor. Use it to get feedback, work through a specific problem, review your work, or get unstuck. You reserve up to 1 hour of their time.

How do I pick a time?

After checkout you pick a slot from Sourav's live availability, and it's confirmed on the spot.

How does the session take place?

Sessions happen over video call. Your mentor shares the meeting link ahead of time, so all you need is a quiet spot and a stable connection.

Can I reschedule?

Yes, up to 24 hours before the session. Message your mentor and find a new time that works for both of you.

What if my mentor doesn't show up?

You're protected. If a mentor is a no-show, it takes one click to cancel and get your money back, no questions asked.

How do refunds work?

You pay securely by card at checkout. If the session can't go ahead, you can cancel and get your money back instantly from your dashboard.
