About me

I'm a backend developer with over 15 years of experience. I build web applications, e-commerce platforms, internal tools, and SaaS products — always from scratch, tailored to the client's needs.

I work primarily with PHP and the Nette Framework, paired with MySQL, Redis, and Elasticsearch. I focus on clean architecture, performance, and long-term maintainability.

I've delivered projects across e-commerce, logistics, IoT, real estate, and more.

What I do

Custom e-commerce

Complete e-commerce systems from order to invoice. Integration with accounting, shipping, and marketing tools.

Backend systems

Robust PHP backends handling thousands of requests per second. Clean architecture, security, testability.

Performance tuning

A slow site costs money. I profile, optimize queries, set up caching, and tune applications for high traffic.

API & integrations

REST APIs for mobile apps, payment gateways, shipping providers, accounting and third-party systems.

SaaS applications

Multi-tenant apps with isolated data, custom billing, and scaling as needed.

Internal tools

CRM, ERP, booking systems, process automation — everything tailored to your needs.
