About Me

Warley Bitencourt profile picture

I am an AWS Certified Solutions Architect Associate building hands-on cloud projects focused on scalability, security, and serverless design.

I started learning AWS with no prior IT background and developed my skills through certifications, consistent study, and practical implementation.

My goal is to grow into a Solutions Architect role by designing reliable, secure, and cost-effective cloud solutions on AWS.

London, UK
Open to Opportunities

Security First

IAM least privilege, secure defaults, and practical cloud security thinking in every design.

Cost Awareness

I focus on efficient architecture choices and prefer managed services when they improve both speed and cost control.

Hands-On Learning

I learn by building, documenting, testing, and improving real projects on AWS.

Credentials

Certifications

Validated AWS knowledge supported by hands-on implementation.

AWS Certified

Cloud Practitioner

Foundation in AWS cloud concepts, security, architecture, pricing, and support.

CURRENT

AWS Certified

Solutions Architect – Associate

Designing secure, scalable, resilient, and cost-optimized AWS architectures using managed services and best practices.

Hands-On Work

Projects

Focused on real-world AWS architecture, combining serverless implementation and system design.

PROJECT 01

AWS Portfolio Platform

Problem

Build a professional cloud portfolio fully hosted on AWS with dynamic backend features, without relying on third-party portfolio platforms.

Solution

Designed a complete serverless platform using S3 for static hosting, CloudFront for global delivery, Route 53 for DNS, ACM for HTTPS, API Gateway and Lambda for backend APIs, DynamoDB for visitor tracking, and SES for contact form notifications.

Key Features

Static website hosting, serverless contact form, visitor counter API, custom domain integration, secure HTTPS delivery, and a fully managed backend with no servers.

PROJECT 02

Global E-Commerce Architecture

Problem

Design a scalable global e-commerce platform able to support rapid growth, secure user authentication, resilient order processing, low-latency product delivery, and workload-specific data services.

Solution

Designed a cloud architecture using Route 53, CloudFront, WAF, Cognito, API Gateway, Lambda, DynamoDB, Aurora, OpenSearch, S3, SQS, and Step Functions. The design separates catalog, search, transactional, and media workloads while using serverless and event-driven patterns for resilience and scale.

What I Learned

How to design from requirements first, select services based on workload patterns, think about blast radius, improve fault tolerance, and document architecture decisions around scalability, security, and cost.

Architecture Documentation

Design Summary

Structured documentation for the global e-commerce architecture, including design goals, service selection, reliability considerations, and security decisions.

Executive Summary

This architecture proposes a scalable cloud design for a global e-commerce platform built to support rapid growth, high availability, low-latency global access, and secure order processing using managed AWS services.

Key Design Decisions

  • Serverless backend: API Gateway and Lambda reduce management overhead and scale automatically.
  • Workload separation: DynamoDB handles catalog and cart access, Aurora manages transactions, and OpenSearch powers product search.
  • Global performance: CloudFront accelerates content delivery for users across regions.
  • Reliable order workflow: SQS and Step Functions improve decoupling, retries, and fault tolerance.
  • Security layers: Cognito, WAF, Shield, IAM, and KMS protect users, APIs, and sensitive data.

What This Project Demonstrates

This project demonstrates requirement-driven architecture design, cloud service selection based on workload type, architecture documentation, and the ability to communicate trade-offs around scalability, reliability, security, and cost.
