I work primarily with Python and backend frameworks such as Django, FastAPI, and Flask, and I have hands-on experience designing REST APIs, microservices, and backend architecture. I have worked on cloud-based solutions using AWS, implemented CI/CD pipelines, and supported distributed systems with tools like Docker, Jenkins, Celery, and Elasticsearch. I am comfortable working with databases and data-heavy systems, including PostgreSQL, MongoDB, DynamoDB, Redis, Spark, Pandas, and Databricks, and I enjoy solving performance and reliability challenges. I have collaborated directly with international clients in English, participated in technical discussions, gathered requirements, resolved production issues, and provided technical support when needed. I value clean code, automated testing, and practical delivery, and I use AI-assisted development tools to improve productivity and code quality. I am open to opportunities where I can contribute to backend engineering, system design, and reliable software delivery in a collaborative environment. ## Skills 48 capabilities[Agile](https://jobicy.com/talent/agile.md)[AWS](https://jobicy.com/talent/aws.md)[Bitbucket](https://jobicy.com/talent/bitbucket.md)[Celery](https://jobicy.com/talent/celery.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[Clean Code](https://jobicy.com/talent/clean-code.md)[Cloudwatch](https://jobicy.com/talent/cloudwatch.md)[CSS](https://jobicy.com/talent/css.md)[Cursor](https://jobicy.com/talent/cursor.md)[Databricks](https://jobicy.com/talent/databricks.md)[Design Patterns](https://jobicy.com/talent/design-patterns.md)[Django](https://jobicy.com/talent/django.md)[Docker](https://jobicy.com/talent/docker.md)[DynamoDB](https://jobicy.com/talent/dynamodb.md)[Elasticsearch](https://jobicy.com/talent/elasticsearch.md)[EMR](https://jobicy.com/talent/emr.md)[ETL](https://jobicy.com/talent/etl.md)[fastAPI](https://jobicy.com/talent/fastapi.md)[Flask](https://jobicy.com/talent/flask.md)[Git](https://jobicy.com/talent/git.md)[GitHub](https://jobicy.com/talent/github.md)[GitHub Actions](https://jobicy.com/talent/github-actions.md)[Gitlab](https://jobicy.com/talent/gitlab.md)[HTML](https://jobicy.com/talent/html.md)[Insomnia](https://jobicy.com/talent/insomnia.md)[Jenkins](https://jobicy.com/talent/jenkins.md)[Kanban](https://jobicy.com/talent/kanban.md)[Lambda](https://jobicy.com/talent/lambda.md)[Linux](https://jobicy.com/talent/linux.md)[Microservices](https://jobicy.com/talent/microservices.md)[MongoDB](https://jobicy.com/talent/mongodb.md)[MySQL](https://jobicy.com/talent/mysql.md)[Pandas](https://jobicy.com/talent/pandas.md)[PostgreSQL](https://jobicy.com/talent/postgresql.md)[Postman](https://jobicy.com/talent/postman.md)[Prompt Engineering](https://jobicy.com/talent/prompt-engineering.md)[Pytest](https://jobicy.com/talent/pytest.md)[Python](https://jobicy.com/talent/python.md)[Redis](https://jobicy.com/talent/redis.md)[REST APIs](https://jobicy.com/talent/rest-apis.md)[S3](https://jobicy.com/talent/s3.md)[Scrum](https://jobicy.com/talent/scrum.md)[Spark](https://jobicy.com/talent/spark.md)[SQL](https://jobicy.com/talent/sql.md)[System Design](https://jobicy.com/talent/system-design.md)[Test Automation](https://jobicy.com/talent/test-automation.md)[Unit Testing](https://jobicy.com/talent/unit-testing.md)[Vue.Js](https://jobicy.com/talent/vue-js.md) ## Experience Career history ### Backend Software Engineer · BMAT Music Innovators Jan 2025 – PresentDevelop and maintain backend applications using Python and Django.
