## About

Professional summarySenior Full-Stack Engineer with 8+ years of commercial experience building SaaS platforms, Microsoft Office Add-ins, offline-first PWAs, backend services and internal business systems.

Over the past five years at Aimtraction, I delivered products for US and international clients in outsourcing and outstaff environments. My work has covered React and Angular frontend architecture, Node.js and Python backend services, complex API integrations, data synchronization, RBAC, deployment automation and end-to-end feature delivery.

Recent projects include Excel and PowerPoint Add-ins, an offline-first logistics platform, an AI-assisted tourism recommendation system, route and trip automation with RabbitMQ and Redis, administration dashboards and internal business tools.

I am comfortable taking a feature from requirements and architecture through implementation, integration, deployment and production support. I also review code, mentor junior developers and help teams improve engineering standards and delivery processes.

Core stack: TypeScript, JavaScript, React, Angular, Node.js, Express.js, Python/Django, Java/Spring Boot, PostgreSQL, Redis, RabbitMQ, Docker, Kubernetes, Azure and CI/CD.

Based in Szczecin, Poland. Open to Senior Full-Stack and Senior Frontend opportunities in Poland and remote teams across Europe.
