Technologies
I deployed small and big projects with this technology, and I have a deep understanding of how it works. I can deploy, manage, and scale applications in Kubernetes clusters, and I have experience with Helm, Argo CD, and KEDA.
I’m a senior Python developer with over 6 years of experience in building and optimizing high-performance systems in cloud environments. I have led the design and implementation of scalable infrastructures, leveraging tools like Flask and FastAPI to ensure reliability and efficiency.
I’m a experienced Docker developer with over 4 years of experience in building and optimizing high-performance systems in cloud environments. I have led the design and implementation of scalable infrastructures, leveraging tools like Docker Compose and Kubernetes to ensure reliability and efficiency.
I use Grafana to monitor services and infrastructure. I have created dashboards to monitor the health of services and infrastructure. I have also used Grafana to create alerts and notifications based on metrics.
I have led the design and implementation of scalable infrastructures, leveraging tools like Terraform and Terragrunt to ensure reliability and efficiency.
Working with FastAPI for a while now. I have used it to create APIs that are used by mobile apps and web apps. Focused on performance and security, FastAPI is my go-to framework for creating APIs.
Used Keycloak to manage authentication and authorization for multiple projects. Created custom themes, custom SPI providers and implemented custom authentication flows.
I have been using Istio for a while now and I am very comfortable with it. I have used it to manage microservices in a Kubernetes cluster. I have also used it to manage traffic routing, security, and observability for my services
I’m currently learning Rust and I’m very excited about it. Used it to build a few small projects and I’m looking forward to using it in more projects where performance is critical.
I created my personal website using Astro. Also I used it to create a internal backoffice solution for another client.
Tools
Used Github Actions to automate the CI/CD pipelines for multiple projects. Deploying to multiple environments, running tests and generating artifacts are some of the tasks that I have automated using Github Actions. Also deployed a self-hosted runners to run the pipelines the company infrastructure.
Used Azure DevOps to automate the CI/CD pipelines for multiple projects. Deploying to multiple environments, running tests and generating artifacts are some of the tasks that I have automated using Azure DevOps. Also deployed a self-hosted agents to run the pipelines in the company infrastructure.
Platforms
Used for many projects and applications. I have experience with GCP services like GKE, VPC, Cloud Run, Cloud Functions, and Cloud Storage. Very comfortable with GCP and have used it to deploy and manage complex applications in production.
Used for many projects and applications. I have experience with AWS services like EKS, EC2, S3, RDS, and Lambda.
I use Vercel to deploy my personal website and other projects. This website is hosted on Vercel and I use it to deploy my Astro projects.
