About Me

I am a Java Backend Engineer with 4+ years of experience building scalable, production-grade backend systems using Java, Spring Boot, and Microservices. I specialize in designing clean REST APIs, asynchronous messaging systems, and backend architectures that are reliable, performant, and cloud-ready.

I have worked extensively in enterprise environments within the financial and retirement services domain, contributing to systems used in real-world production scenarios. My focus is on backend performance optimization, distributed system fundamentals, and writing maintainable backend code.

Projects

Event-Driven Order Processing System

A backend system designed to demonstrate real-world microservices communication using an event-driven architecture.

Architecture Overview

Independent Spring Boot microservices
Kafka-based asynchronous communication
Loose coupling between services
Scalable and fault-tolerant design

Key Components

Order Service: REST APIs to create and fetch orders, publishes order-created events
Payment Service: Consumes order events and processes payment logic
Inventory Service: Updates stock based on payment status
Notification Service: Sends notifications based on inventory updates (mocked)

Technical Highlights

Kafka producers and consumers with JSON serialization
Caffeine Cache to reduce database calls and improve response time
Docker Compose for local orchestration
Layered architecture for maintainability

Why this project matters: This project reflects how modern product companies design backend systems to handle scale, asynchronous workflows, and service decoupling.
