About Me

I am a dedicated software engineer with expertise in designing and developing scalable solutions using Python (Django, FastAPI, Celery) and JavaScript. My experience includes working extensively in cloud environments with AWS, containerizing applications using Docker, and managing infrastructure through DevOps tools like Kubernetes, ECS, and Terraform.

Throughout my career, I have led the migration of applications into Docker, implemented CI/CD pipelines using GitLab and Ansible, and developed data processing systems leveraging TensorFlow. I have also integrated Stripe for payment solutions, built GraphQL gateways over gRPC services, and worked on large-scale content management systems.

My passion lies in solving complex problems with innovative solutions, whether it's optimizing infrastructure, building robust backend systems, or integrating third-party services. I take pride in my ability to create reliable, high-performance applications that meet client needs.

Experience

• Designed and supported solutions based on microservices architecture
• DevOps practices (AWS, Docker, ECS, Terraform, Kubernetes)
• Migrated applications into Docker containers
• Maintained and improved existing customer solutions
• Designed and implemented integration solutions to interface with 3rd-party software
• Integrated Stripe payment solutions
• Implemented automatically generated GraphQL gateway over gRPC services
• Developed a content management system using Django to manage multilingual mobile app content
• Built a web application (AngularDart frontend, Golang backend) for managing large amounts of audio and text data
• Set up CI/CD system using GitLab, Docker, and Ansible for bare-metal servers
• Created data storage systems, text/audio preprocessing systems using TensorFlow, and trained a speech recognition model for CMU Sphinx

Technologies

• Python (Django, FastAPI, Celery): Developed scalable backend applications, built API solutions, and managed distributed tasks with Celery in microservices architecture.
• JavaScript (AngularDart): Created dynamic and interactive frontend user interfaces for web applications, focusing on managing large data sets (audio/text).
• DevOps (AWS, Docker, ECS, Kubernetes, Terraform): Migrated applications to Docker containers, automated infrastructure setup, and deployed applications on cloud platforms like AWS, using tools such as ECS and Kubernetes for orchestration.
• CI/CD (GitLab, Ansible): Set up continuous integration and delivery pipelines using self-hosted GitLab, Docker, and Ansible, automating deployments for bare-metal servers.
• Cloud Infrastructure (AWS): Managed AWS cloud services, implemented cloud-native architectures, and handled scaling and deployment of cloud applications.
• Payments Integration (Stripe): Implemented payment solutions, integrating with Stripe to handle secure transactions and automate billing systems.
• GraphQL & gRPC: Created a GraphQL gateway automatically generated over gRPC services to provide a flexible and efficient API layer.
• Data Processing (TensorFlow, CMU Sphinx): Developed systems for text and audio data preprocessing using TensorFlow, and trained speech recognition models with CMU Sphinx.
• PostgreSQL: Optimized and maintained relational databases, ensuring high performance and scalability in various applications.
• Golang: Built backend services for managing large datasets and processing user inputs, specifically in the context of handling audio and text data.
