About Mateusz

I help startups and businesses build scalable SaaS platforms, enterprise software and AI-powered applications. Over the last 10+ years I have successfully delivered commercial software products that are used daily by real users and generate revenue for my clients.

As the founder of Hermsoft, I have personally led the design and delivery of numerous commercial software products for startups, SMEs and enterprise clients. The solutions I build are used in production, automate business processes and support thousands of daily users.

• 10+ years experience
• 30+ software projects delivered
• Production-ready systems
• International clients
• End-to-end delivery

My expertise includes:
• ASP.NET Core
• C#
• Microsoft Azure
• AI & LLM integrations
• React & Flutter
• PostgreSQL & SQL Server
• Docker
• CI/CD & DevOps
• REST APIs & system integrations
• Performance optimization
• Cloud architecture & scalable systems


I combine hands-on development with strong architectural thinking, allowing me to solve complex technical challenges while keeping projects maintainable, scalable and business-focused.

I enjoy working directly with founders, startups and enterprise teams, helping them transform ideas into reliable, production-ready software. Whether you need a senior developer, technical lead or someone who can take ownership of an entire solution, I focus on delivering high-quality software that creates long-term value.
