Krakow, Poland - 8:07 pm local time
Senior Python / Data / Cloud Engineer with 6+ years of experience delivering production-grade systems for fintech, enterprise, and high-scale data environments.
I specialize in building high-performance backend services, designing and optimizing data pipelines, and implementing automation in AWS. I’ve contributed to complex, business-critical systems for organizations including Citi, NASK, FTMO, Warbud and others.
I help companies deliver reliable, scalable solutions such as:
* Backend services (FastAPI, Flask, microservices, integrations)
* Data pipelines & ETL workflows (Airflow, AWS Glue, Step Functions)
* Process automation & data engineering
* SQL optimization and data modeling
* Serverless & cloud architecture (Lambda, S3, ECS, IAM, RDS)
* Microservices
* CI/CD, IaC, production-ready deployments
My approach: fast analysis, clean and maintainable code, clear communication, and stable production delivery.
If you need a robust backend, a scalable data workflow, or a well-architected system in AWS — I can help you deliver it quickly and efficiently.

Getting info before work can be started
I will contact the client with exact questions I need to start-to-finish work. If prefered by client - We can catch-up by zoom for 45 minutes video-call. We will agree on best time to contact taking timezone differences into consideration.
My work is in progress - daily updates for the client.
I'm preparing solution, we can catch-up for few minutes daily calls or I can describe progress by message. Optionally I will collect additional info If I need. Additional changes to API Structure or Data schema are still possible.
