Building data-intensive systems that power real products
I design and build backend infrastructure, data pipelines, and large-scale crawlers. Available for long-term projects — Prague, Brno, Bratislava or remote.
Languages and tools I use daily to build, deploy, and maintain production systems.
Custom software, data automation, and system integration — built for your business.
I build the software behind your website or app — user accounts, data management, automation, and everything that makes your product work.
Automatic systems that collect, process, and organize data for you. Market research, reports, monitoring — set it up once and get results continuously.
Making your existing tools and services work together. Payment systems, email, analytics — one smooth workflow without manual data moving.
Maintenance, optimization, and making sure your system stays fast and reliable as your business grows.
