About Evgeniy
AI Engineer, Python Backend Developer, Solution Architect
Krakow, Poland - 8:53 pm local time
My background includes designing microservices, developing ETL pipelines for IoT and analytics platforms, integrating with third-party services, and implementing ML-powered features. I’m comfortable working across R&D environments, validating hypotheses, and delivering production-ready solutions with clean architecture (DDD), strong system design, and solid business understanding.
I’ve worked on agricultural IoT platforms, blockchain trading systems, digital marketing tools, and apps for travelers and expats—building everything from prototypes to scalable, reliable backend services.
If you need someone who can architect a solution, build it end-to-end, optimize it, and integrate AI or automation where needed, I can help you deliver it efficiently and professionally.

Delivery time starts when Evgeniy receives requirements from you.
Evgeniy works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & Domain Analysis
We analyze your business logic, user stories, and define a shared language. We finalize API specs together to ensure perfect alignment.
Architecture Design & Planning
I design and approve the system architecture: API schemas, data models, auth strategy, and scaling approach. Solid foundations first.
