Cloud Architecture: Designing and managing AWS-based solutions (ECS, EC2, Lambda, IAM, API Gateway, S3, SNS, SQS, VPC, Elasticache, DynamoDB ...) to enhance performance and scalability.

Infrastructure as Code (IaC): Using Terraform and CloudFormation to automate consistent infrastructure setup.

CI/CD Pipelines: Streamlining deployments with Jenkins, GitLab CI, and GitHub Actions for faster and more reliable releases.

Containerization & Orchestration: Using Docker and Kubernetes to manage scalable and reliable services.

Monitoring & Optimization: Real-time performance insights and issue resolution with Datadog, Sentry, and the Elasticsearch Stack (Elasticsearch, Logstash, Kibana) for in-depth monitoring and log analysis.

Microservices Architecture: Designing and managing microservices using DDD and hexagonal patterns for modular and scalable systems.

API Development: Creating secure, efficient RESTful APIs with AWS API Gateway for robust integration.

Database Management: Optimizing MongoDB, PostgreSQL, Redis, DynamoDB, MySQL, and AWS ElastiCache for reliable, scalable data storage and high-performance applications.

Backend Frameworks: Developing maintainable, high-quality code in Node.js and TypeScript, leveraging frameworks like Express and Nest with dependency injection to enhance modularity and meet performance standards..

Scalability & Performance: Enhancing system reliability and user experience by optimizing high-traffic systems.

Testing & Quality Assurance: Ensuring code reliability and robustness through comprehensive testing practices, using tools like Sinon, Mocha, Chai, and Jest to conduct unit, integration, and end-to-end tests.
