Understood CloudWatch and SNS

Hello Connections My current work contract is ending soon, so I’m looking for new job opportunities or freelancing projects. I’m a Java Full Stack Developer (Java, Spring Boot, React, SQL) and would love to connect. Any tips, referrals, or advice would mean a lot

Terraform = IaC tool → create/update/delete infra with 1 command. Resource Explorer = search engine → find AWS resources across regions/accounts. Cost Explorer = track bills → map costs to projects. Common to all → Tags. Always tag resources to avoid unnecessary bills!

This week, I worked on the complete app deployment using GitHub, S3, CodeDeploy, and Load Balancer, and understood some new AWS services All created using Terraform

Studied some memory management concepts in Java

Last week, Explored some Recursion and backtracking problems

First time i solved DP question by myself. Feel Good

Understood ELB (Elastic Load Balancer) and Auto Scaling Group in EC2. Experienced in live load balancing, auto scaling, and self-healing concepts. Also routed traffic with Route 53 for a custom domain.

CloudWatch vs CloudTrail: - CloudWatch = metrics, logs, alarms - CloudTrail = who did what, when - CloudWatch = performance + health - CloudTrail = governance + audit Together = observability + security.

Kubernetes is tough .... #k8s

Last week, I revised and solved some problems on the queues.

Day 87 of My Java Backend Journey - Understand docker compose and implemented it using Spring Boot and psql - Concept of mullti stage build - Local Build - Build directly inside Docker (single stage) - Multlti stage build - Reduce image size

Day 86 of My Java Backend Journey - Basics of Docker - Virtualization vs Containerization - Docker Architecture - Installing Docker on EC2 + Common Issues - Docker Terminologies (Image, Container, Dockerfile) - Commonly Used Commands - Running a Spring Boot inside Docker

Summary of what I learned: - AWS S3 integration - Advanced Spring Boot config - Real use of annotations & design patterns - Query optimization - Full email feature with status tracking

Internally, Spring used the Strategy Design Pattern. Next, I had to show email status and count on the frontend. To optimize DB calls, I explored: -Projections - Criteria API - Specifications Everything fetched in a single efficient query!

Spring's TemplateResolver supports only local templates, so I had to extend it to handle S3-based dynamic ones. This required understanding and using core Spring concepts: @Bean @Configuration @Qualifier @Primary I never used these before in real projects, now I’ll never forget!

To send emails, I worked with two types of templates: - Local templates (from resources folder) - Dynamic templates (stored in AWS S3) I integrated AWS S3 with Spring Boot to load dynamic templates.

Day 85 of My Java Backend Journey Last week was hectic, but it was also filled with real-world learning. I implemented email sending using the Brevo API in Spring Boot. 👇

That is a good explanation I tried the same with lombok builder a long time ago, but your approach is good.
