Senior Python Backend Engineer

I am a senior backend engineer with 4+ years of experience building high-throughput microservices and backend systems. I have worked extensively with Python and modern backend frameworks, and I focus on creating reliable, scalable, and maintainable solutions.

I have a strong track record of improving system performance at scale. In my work, I helped optimize systems serving 54M+ users, reducing queries by 77%, improving response times by 75%, and lowering bugs by 40%.

My technical background includes Python, SQL, FastAPI, Flask, Django, PostgreSQL, Elasticsearch, Redis, RabbitMQ, Kafka, Celery, Docker, Kubernetes, Jenkins, and CI/CD. I also have experience with testing tools such as Pytest and Unittest, as well as ORM and database optimization with SQLAlchemy.

I have contributed to projects in information security, fintech CRM microservices, and automation tools. My responsibilities have included developing email security components, integrating enterprise mail gateways, designing document workflows, building Telegram bot platforms, and creating admin panels.

I also bring experience in architecture, reliability, and team leadership. I have designed state-driven workflows, implemented fault-tolerant integrations, improved test coverage, and mentored junior developers to production readiness.

I am currently seeking a senior backend role in Europe, preferably in Germany, the Netherlands, or Poland. I am open to relocation and visa sponsorship.
