As a software architect with over 10 years of experience, I specialize in building highly available applications from scratch. My expertise lies in Python and Django, and I have built multiple applications with efficient business logic handling. In addition, I have a strong skill set in both frontend and backend development, allowing me to work with clients from conception to deployment.
I have extensive experience in designing and developing applications from the ground up. I can work with clients to identify their business requirements and translate those into a functional application design. I have a deep understanding of user experience (UX) design principles and can create an interface that is intuitive and easy to use.
When it comes to backend development, I am proficient in Python and Django. I have worked on numerous projects that require complex business logic handling, such as e-commerce platforms, advanced CRMs, banking/invoicing solutions, and enterprise level systems. I can also integrate databases, such as PostgreSQL, to ensure that the application has a solid foundation.
On the frontend, I am skilled in Angular and have basic knowledge of React. I can create responsive designs that look great on desktops, tablets, and mobile devices. I have a solid understanding of HTML, CSS, and JavaScript, which allows me to create dynamic and interactive interfaces.
In addition, I have experience working with DevOps tools such as GitLab CI/CD and ArgoCD. I can automate the deployment process, ensuring that the application is deployed seamlessly and quickly. I am also proficient in container orchestration tools such as Kubernetes, which allows me to manage and scale applications in a dynamic environment.
I have worked extensively with cloud platforms, specifically Amazon Web Services (AWS). I can design and implement highly available and scalable applications that can handle high volumes of traffic. I have experience with AWS services such as EC2, S3, RDS, Lambdas, EKS, Secrets manager, MSK, SQS and CloudFront.
I am committed to delivering high-quality work on time and within budget. I have excellent communication skills, and I can work closely with clients to ensure that their needs are met. I am highly adaptable and can work on projects of any size or complexity. I am passionate about technology and am constantly learning and improving my skills.
One of my top priorities when developing software is ensuring that the code is of the highest quality. I believe that clean, well-structured code is crucial for maintainability and scalability. To achieve this, I use continuous integration (CI) tools such as GitLab CI/CD and Github actions, along with code analysis tools like Ruff, Flake8, Black and Pylint. I also use pre-commit hooks to ensure that code is properly formatted and adheres to best practices before it is committed. In addition, I perform proper license checks on all third-party packages used in my projects to ensure compliance with licensing requirements. By focusing on code quality, I can deliver reliable and maintainable software that meets the highest standards.
Overall, my strong skill set and experience in software architecture, Python and Django, frontend and backend development, cloud platforms, DevOps tools, and container orchestration make me an excellent choice for any freelance project.
