2Semester-by-semester detailed study plan

03

Semester 3 · Programming foundation

Master Java and developer fundamentals

Your university DSA and COAL courses remain the academic priority. The side-study goal is to transition confidently from C++ into professional Java development.

Side courses, in order

Git and GitHub — branches, merges, pull requests, rebasing basics.
Java fundamentals — Java syntax, OOP, interfaces, abstract classes, collections, generics, exceptions.
SOLID principles and clean code.
Linux terminal fundamentals.
JUnit basics and debugging.

AI engineering track

Learn context engineering, structured prompts, AI code review, and responsible use of Claude Code or GitHub Copilot. Practice giving an agent a small, well-specified task and checking its output.

Final project

Build Your Own Redis in Java

A TCP server that speaks the Redis protocol (RESP): SET/GET with expiry, lists, pub/sub and optimistic locking, backed by your own data structures, with unit tests and a clean GitHub repository.

Build Your Own Redis in JavaReinventing D Wheel · YouTube

Why this semester

Your first real Java project: it turns this semester's Java, OOP and collections into a working server, and puts your DSA course (hash maps, lists) to direct use.

Completion test

You can independently build, test, debug, and explain a Java program, and redis-cli can talk to your server.

04

Semester 4 · Backend development

Become a Java backend developer

Side courses, in order

Advanced Java — streams, concurrency basics, JVM concepts.
Spring Framework and Spring Boot.
REST API design and HTTP fundamentals.
PostgreSQL — SQL, joins, indexes, normalization, transactions.
Spring Data JPA and Hibernate.
JUnit, Mockito, and Spring Boot integration testing.

AI engineering track

Use AI to draft API specifications, identify edge cases, generate test suggestions, review database designs, and complete bounded coding tasks.

Final project

Write a Database from Scratch

A storage engine with fixed-size pages, a page buffer, B+tree indexes (including non-unique keys), and queries with filtering, sorting, offset and limit. Build it in Java to keep strengthening your main language.

Write a database from scratchCode With Sep · YouTube

Why this semester

You are learning PostgreSQL indexes, joins and transactions this semester; building the engine yourself shows what happens underneath every query you write.

Completion test

You can explain how your B+tree finds a row, why an index speeds up a query, and how that maps to PostgreSQL, alongside a tested Spring Boot REST API built without tutorial guidance.

05

Semester 5 · Production engineering

Build production-ready backend systems

Side courses, in order

Spring Security — authentication, authorization, OAuth2 fundamentals.
Docker and Docker Compose.
Linux deployment and server administration.
GitHub Actions for CI/CD.
AWS fundamentals — IAM, EC2, RDS, S3, networking.
Redis caching, basic observability and monitoring.

AI engineering track

Learn repository-aware coding agents, AI-assisted test generation, pull request review, and debugging CI/CD failures. Keep secrets and production credentials outside untrusted AI tools.

Final project

Build Your Own Private Search Engine

Self-host a private search engine (SearXNG) on a Linux cloud server with Docker Compose, a reverse proxy, HTTPS, access control, automatic updates and monitoring, so your searches never build a profile for big tech.

ditch Google!! (build your own PRIVATE search engine)NetworkChuck · YouTube

Why this semester

Practises exactly this semester's stack: Linux servers, Docker, networking, HTTPS and security hardening, on a real public deployment.

Completion test

Someone else can follow your documentation to deploy the search engine on a fresh server, and you can explain every layer from DNS to container.

Career milestone

Start applying for backend internships during this stage rather than waiting for graduation.

06

Semester 6 · Distributed fintech systems

Distributed systems and fintech engineering

Side courses, in order

Microservices architecture and service communication.
Apache Kafka or RabbitMQ.
Distributed systems fundamentals — consistency, fault tolerance, timeouts, retries.
Database isolation, concurrency, and transactions.
Idempotency, transactional outbox, event-driven architecture.
Payment systems basics — transaction lifecycle, ledgers, reconciliation.

AI engineering track

Begin Python, LLM APIs, structured outputs, tool calling, and AI application security. Learn how to expose authorized backend information to AI tools safely.

Final project

Distributed Payments & Wallet Platform

Your own event-driven payments core: users hold wallets, send money to each other and pay merchants, and every transfer flows through Kafka as a chain of events across independent microservices. Built in Java and Spring Boot and designed entirely by you, with no tutorial.

What you will build

MicroservicesAccount, Wallet, Payment, Ledger and Notification services behind an API gateway, each owning its own PostgreSQL database
KafkaApache Kafka as the event backbone, with topics partitioned by account ID so events for one wallet stay in order, and consumer groups for scaling
Event-driven transactionsTransfers as event-driven transactions: a choreographed saga (debit → credit → confirm) with compensating events that roll back when a step fails
Idempotency + outboxA transactional outbox on every service and idempotent consumers, so each event changes state exactly once even when Kafka redelivers it
Fault toleranceTimeouts, retries with exponential backoff, a dead-letter topic and a small tool to replay failed events
Isolation + concurrencyConcurrent transfers on the same wallet kept correct with row locks or optimistic versioning, proven by a concurrency test
Payments + ledgersA double-entry ledger, a payment lifecycle state machine, signed webhooks from a fake payment gateway and a nightly reconciliation job
KubernetesAll services, PostgreSQL and Kafka running on a local Kubernetes cluster (kind or minikube) with health probes and config in ConfigMaps and Secrets

Why this semester

Every side course of this semester becomes a requirement: microservices, Kafka, distributed-systems fundamentals, isolation, idempotency with the outbox, and payment ledgers.

Completion test

Demonstrate why retries don't result in duplicate transfers and how the ledger remains consistent, even when a service or Kafka broker crashes mid-transfer.

Career milestone

Aim to obtain a backend internship by this stage. Apply more widely than Tamara so you gain real team experience.

AI track side project

Build Self-Learning AI Agents (Python)

A Python agent that calls tools with structured outputs and learns from what worked on earlier runs: practice for this semester's AI track (Python, LLM APIs, tool calling).

07

Semester 7 · Reliability and intelligence

Advanced system design and AI engineering

Side courses, in order

High-level system design — load balancing, caching, sharding, scaling.
Advanced distributed systems and reliability.
Kubernetes fundamentals.
Observability — OpenTelemetry, distributed tracing, metrics.
Load testing, performance profiling, and incident response.
Go fundamentals, only after your Java skills are strong.

AI engineering track

Study RAG, embeddings, vector search, AI agent orchestration, MCP, tool permissions, evaluation datasets, tracing, and human approval workflows.

Final project

Flash-Sale Ticketing Platform

A ticket-booking system built for the hardest moment in system design: a concert goes on sale and 50,000 people try to grab 5,000 seats in the same minute. You design it from a blank page, run it on Kubernetes and prove with load tests that it never sells the same seat twice.

What you will build

System designA written system design first: requirements, capacity estimates (QPS, storage), API, data model, high-level diagram and the trade-offs you chose
Load balancingAn ingress load balancer and API gateway with per-user rate limiting and a virtual waiting room for traffic spikes
Event-driven transactionsSeat reservation as an event-driven transaction over Kafka: hold → pay → confirm, or expire and release, with no overselling under heavy contention
Caching + CQRSCQRS: writes go through events while seat-availability read models live in Redis, kept fresh by Kafka consumers
Sharding + scalingBookings sharded by event ID with consistent hashing, and Kafka partitions sized so consumers scale out horizontally
KubernetesKubernetes with horizontal pod autoscaling, rolling deployments, pod disruption budgets and Kafka running as a StatefulSet
GoA high-throughput seat-hold expiry and queue service written in Go
ObservabilityOpenTelemetry traces that follow a booking across services and Kafka hops, plus metrics, SLOs and dashboards
Load testing + profilingk6 load tests that replay a flash sale, profiling of the slowest service and the fixes you made
Reliability + incidentsChaos drills (kill a Kafka broker, a pod, a shard), each followed by a written postmortem

Why this semester

A pure system-design and microservices project: load balancing, caching, sharding, scaling, Kubernetes, observability, load testing, incident response and Go, all under real contention.

Completion test

At peak load, show zero oversold seats and explain p99 latency, Kafka consumer lag, cache hit rate and how the system recovered from a broker failure, using your own traces and dashboards.

Career milestone

Begin serious preparation for Tamara-style Java, SQL, distributed-systems, and backend interviews.

Optional systems side project

C++ Compiler in C++

A compiler for a small C-like language (lexer, parser, AST, x86-64 code generation) that builds on your COAL and DSA knowledge. lolzdev builds his in C; you write yours in C++.

08

Semester 8 · Industry readiness

Industry readiness and job applications

Side courses, in order

DSA interview practice using Java.
Low-level design — classes, interfaces, SOLID, design patterns.
High-level design — wallets, payments, event-driven systems.
Advanced Spring Boot and SQL interview revision.
Concurrency, debugging, and distributed systems revision.
Behavioral interviews, teamwork, architecture presentations, and technical writing.

AI engineering track

Practice complete AI-assisted delivery workflows, security review, evaluation, AI-supported incident response, and cost/reliability trade-offs.

Final capstone

Production-Grade Distributed Redis

Polish your strongest project. Recommended: turn your Semester 3 Redis into a distributed service with replication, persistence (snapshots and append-only log), Docker deployment, metrics and tracing, a load-test report, architecture diagrams and security notes. Alternative: polish your Semester 6 payments platform or Semester 7 ticketing platform to the same standard.

Why this semester

Brings the whole journey together: the Java of Semester 3, the storage ideas of Semester 4, the DevOps of Semester 5, the microservices of Semester 6 and the system design of Semester 7.

Completion test

Confidently defend every architectural decision and complete realistic technical interviews without AI help.

Career milestone

Apply for eligible Tamara junior engineering vacancies and graduate opportunities before graduation, while keeping other fintech and backend companies as parallel targets.

5Your graduation readiness checklist

6Important Tamara hiring consideration

However, a previous Backend Engineer I Builders Program description specifically targeted Saudi graduates. I cannot confirm whether the current program accepts you as a Pakistani applicant. Regular engineering vacancies may have different requirements.

That is why your plan should be Tamara-targeted but not Tamara-dependent: develop engineering skills that qualify you to compete for backend positions at fintech companies internationally.

Your final learning strategy

70%

Deep backend engineering

Java, Spring Boot, SQL, distributed systems, system design, cloud, and production reliability.

20%

AI-native engineering

AI-assisted development from Semester 3, with LLM APIs and agents added when your backend foundations are ready.

10%

Career preparation

GitHub portfolio, interview practice, applications, communication, and professional connections.

The percentages are a suggested overall emphasis, not a rigid weekly formula.

Your guiding principleBecome the engineer who understands how systems should behave, can build and operate them, and knows how to use AI safely to increase the speed and quality of engineering work. That is a stronger long-term strategy than relying on AI to generate code without understanding it.
