What's Being Built

Same rule as the Careers Hub — free, no signup, no email wall.

AI Engineering 4 Tracks

AI & LLM Foundations

What a model is really doing, minus the hype.

  • How LLMs actually work
  • Tokens & context windows
  • Prompt engineering that holds
  • Picking a model per job

RAG & Vector Search

Giving a model your data without fine-tuning it.

  • Embeddings explained
  • Chunking strategies
  • pgvector & similarity search
  • Making retrieval accurate

AI Agents & MCP

Where the industry is hiring hardest right now.

  • Tool calling & schemas
  • Agent loops that terminate
  • MCP servers & clients
  • Guardrails & evals

Shipping AI Features

The engineering around the model, which is most of it.

  • Streaming responses
  • Cost & latency budgets
  • Caching & rate limits
  • Failure modes & fallbacks
Tech Stack 4 Tracks

Docker & Containers

The skill that quietly appears in every JD.

  • Images vs containers
  • Compose for local stacks
  • Slim production images
  • Debugging a dead container

Cloud & Deployment

Getting it off your laptop and keeping it up.

  • Nginx & reverse proxies
  • Environments & secrets
  • CI/CD pipelines
  • Zero-downtime deploys

Microservices & Messaging

Including when not to split at all.

  • REST vs events
  • Kafka & queues

  • Tracing across services

Angular & Frontend

For the UI devs the job map also covers.

  • Components & signals
  • RxJS, the useful parts
  • State without the pain
  • Talking to a Java API
Core Backend 4 Tracks

Java Fundamentals

The parts interviewers actually probe, not the whole language.

  • Java 8 streams & lambdas
  • Java 11 & 17 LTS additions
  • Java 21 virtual threads, records
  • Collections, concurrency & GC

Spring Boot

From annotation to production — how it actually works.

  • Boot internals & auto-config
  • Dependency injection
  • REST API design
  • Data & transactions

SQL & Data

Where most backend candidates quietly lose the round.

  • Joins that don't blow up
  • Indexing & query plans
  • Transactions & isolation
  • Modelling exercises

System Design

Scoped for 0–4 yrs — the questions asked at this level.

  • One project, deeply
  • Microservices trade-offs
  • Caching & queues
  • Whiteboard patterns
Getting Hired 3 Tracks

DSA & Problem Solving

Enough to clear the round — not a competitive-programming detour.

  • Patterns, not 500 problems
  • Arrays, strings & hashmaps
  • Trees, graphs & recursion
  • Complexity in plain words

Interview Prep

The loop itself: what gets asked, and how to answer it.

  • Company-wise patterns
  • Behavioural rounds
  • Project deep-dives
  • Salary negotiation

Resume & Profile

Getting past the filter before a human ever reads it.

  • ATS-safe formatting
  • Naukri keyword tuning
  • LinkedIn recruiters find
  • Project write-ups
