Full Stack Developers Certified Professional equips you with skills from front-end design to full deployment pipelines. It teaches modern tools for building complete applications end-to-end. This refreshed guide dives deeper into Full Stack Developers Certified Professional with expanded hands-on steps and real-world insights.
Detailed Journey from Waterfall to DevSecOps
Software development evolved from waterfall’s strict, linear steps that often led to long delays and difficulty handling changes. Agile improved teamwork and flexibility through sprints but still struggled with deployment speed and integration issues. DevOps introduced CI/CD pipelines for automated, frequent releases while DevSecOps embeds security checks right from the code stage .
SRE practices focus on system reliability, error budgets, and toil reduction to keep services running smoothly at scale. These models address key pains like manual handoffs, waste in rework, and siloed teams by promoting shared responsibility and continuous improvement. Understanding DevOps values—such as collaboration, automation, and fast feedback—helps teams boost productivity while managing enterprise adoption challenges like cultural shifts and tool integration risks .
In-Depth Microservices Fundamentals and Patterns
Microservices architecture breaks monolithic applications into independent, loosely coupled services for easier scaling and maintenance. Core patterns include choreographing services via events, separating presentation components, business logic, and database access logic. Application integration uses APIs or message queues, while modeling ensures clear boundaries .
Teams learn what to test (unit, integration, contract), when (shift-left), and how to prepare for deployment with canary releases. Monitoring covers performance metrics, logs, and traces using tools like Prometheus. Container demos highlight avoiding breaking changes, choosing sync/async protocols (REST vs Kafka), and handling legacy migrations through strangler patterns. This approach reduces downtime and speeds innovation .
Comprehensive OS Foundations: CentOS and Ubuntu
Start by installing CentOS7 or Ubuntu on local machines or VMs. Gain secure remote access via SSH with key-based authentication. Master command line essentials: reading files with cat/less, editing via vi (insert, command, visual modes), pipingping (grep|awk) for data processing, and redirection (> >>) .
Archiving uses tar/gzip, permissions (chmod/chown) prevent unauthorized access, and root/sudo requires careful use with tools like screen for persistent sessions. These skills form the bedrock for server management and scripting.
Advanced Virtualization: VirtualBox and Vagrant Workflows
Hypervisors like VirtualBox enable isolated environments; install and create CentOS/Ubuntu VMs with snapshots for quick resets. Vagrant streamlines this: basic workflow (up/destroy), advanced (multi-machine), Vagrantfile configs for provisioning (shell/ansible), networking (private/public/bridged), and synced folders .
Install Nginx via provisioners, share sites with vagrant share, and version configs. This setup mimics production for safe experimentation.
Expanded AWS Hands-On with Key Services
AWS Free Tier lowers entry barriers; understand global infrastructure (regions, AZs). IAM covers users, roles, policies, MFA for least privilege. EC2 labs: launch instances, security groups, user data scripts .
Storage deep dive: EBS volumes (gp3/io2), snapshots; S3 buckets (versioning, lifecycle, encryption); EFS for shared file systems. RDS MySQL: multi-AZ, backups, read replicas. ELB: ALB/NLB setup, health checks; VPC: subnets, NAT, peering.
Docker Mastery: From Basics to Deep Dives
Containers virtualize OS, lighter than VMs. Docker architecture: client/server, engine, registries. Install/config, build first image, manage containers (run/ps/stop). Dockerfile best practices: multi-stage, .dockerignore .
Deep dives: image layers, networks (bridge/overlay), volumes (bind/named), resource limits (CPU/memory), compose for stacks (Java/Rails/PHP/Node with yaml services, depends_on, ports).
Jira and Confluence for Agile Planning
Jira: install Linux/Windows, projects (classic/next-gen), issues (epics/stories), workflows, custom fields/screens, JQL searches, GitHub integration, plugins. Agile boards: sprints, burndown .
Confluence: spaces/pages, templates, users/groups/permissions, macros, backups, addons. Customize dashboards for team collaboration.
Java Backend: Fundamentals to Deployment
Setup JDK, fundamentals (primitives, arrays, loops), methods, conditionals, exceptions, OOP (classes/inheritance/polymorphism). Build JAR/WAR, deploy Tomcat.
Python: Scripts to Advanced Structures
Interpreted ease, versions (3.x), scripts, strings/math ops, flow (if/while/for), data (lists/tuples/sets/dicts), functions (args/kwargs/lambdas), files/JSON/pickle, exceptions.
Frontend Core: HTML, CSS, JavaScript Projects
HTML: semantics, forms, tables, media. CSS: selectors (class/id/combinators), box model, flex/grid. JS: DOM, events, arrays/objects, async/await .
Project: Responsive website with navigation, forms, animations.
Git Complete Version Control Guide
Distributed VCS history; install/config all OS. Init/commit/branch/merge/rebase, diffs/logs, stashes/remotes (clone/push/pull), tags (light/annotated), .gitignore. Real project: California site edits, resets .
SonarQube for Secure Code Analysis
Install server/scanner, analyze projects, dashboard (issues/measures/duplications), rules/plugins, branch analysis.
MySQL 8: Architecture to SQL Mastery
Install/upgrade, my.cnf tuning, users/databases, InnoDB (transactions/MVCC), SQL (queries/joins/DML/DDL), troubleshooting.
Build Tools: Gradle, Artifactory, Packer
Gradle: tasks/dependencies/plugins, multi-project. Artifactory: repos (local/virtual), Maven deploy. Packer: AWS AMIs, provisioners (Ansible), pipelines .
Frameworks: Bootstrap, jQuery, Nginx, Spring
Bootstrap: responsive grid/components (navbars/modals). jQuery: selectors/events/AJAX. Nginx: vhosts/SSL/rate-limit/gzip . Spring: IoC/beans/XML/Java config.
Testing: JUnit and PyTest Thoroughly
Unit testing value; JUnit5 (asserts/params/@Test), PyTest (fixtures/markers).
Jenkins CI/CD: Full Enterprise Setup
Freestyle/pipeline jobs, triggers/plugins (20+ top), nodes HA, integrations (Git/Sonar/AWS/Docker), reports/notifications, security/backup. Covers Java/Python/C++/NET .
