I’m a software developer at ADSM sp. z o.o. with 5+ years of experience building and shipping web systems — from frontend, through backend APIs, to deployment on Linux.

I like working on products that actually help people. If you’re building something meaningful (for users, teams, or society), I’m always happy to connect and talk.

• Frontend: React, TypeScript, JavaScript, Tailwind / CSS
• Backend: C# / ASP.NET, Entity Framework, PostgreSQL
• Automation: Python scripting (automation, tooling, glue code)
• Delivery: CI/CD, Docker, Linux deployments, self-hosting

• Saloonik (Owner)
  I’m the owner of Saloonik and I build both:
  • saloonik/system.saloonik.com — management system (TypeScript)
  • saloonik/api.system.saloonik.com — API (C#)
• CarrMan
  As part of my work, I’ve delivered frontend features and improvements with 600+ commits.

I’m security-oriented: I care about secure design, input validation, protecting secrets, least privilege, dependency hygiene, and safe deployment practices.
