I'm a senior software engineer at Booking, where I currently build our customer data platform. Before that I worked on infrastructure and security teams - so I'm comfortable owning a system end to end, from the data layer up to the parts that have to stay reliable and secure under real production load. What I do best: - Data platforms & backend systems - designing and building customer data infrastructure: pipelines, data modeling, and the services around them. - Infrastructure & security -production systems, deployment and reliability work, and building with security considered from the start rather than bolted on. - Mobile development - native Android applications, and iOS as well. From first prototype to a shipped app. - Algorithms & problem-solving - a strong mathematical background I lean on for anything performance-sensitive or algorithmically demanding. Math has been part of my work for a long time. I ranked in the top 3 at my national mathematics olympiad and was a member of my country's IMO team. I hold a BS in Computer Science and have taught Linear Algebra, Calculus, and Introduction to Algorithms at university level - which means I'm used to explaining technical decisions clearly, not just making them. I'm based in the Netherlands and work fluently in English, Kazakh, Russian, and Turkish (plus basic Dutch, A2). If you're building something in the data, backend, or mobile space and want a partner who'll think carefully about the design before writing the code - I'd be glad to hear about it.

I don't just configure servers. I build the software that makes them fast. As the maintainer of 100+ NGINX modules and RPM packages running on thousands of production servers worldwide, I bring a depth of expertise most server admins simply can't match. When you hire me, you're not getting someone who follows tutorials. You're getting the person who writes the software those tutorials are about. My background: 18 years in Linux infrastructure. Software Developer at CloudLinux from 2022 to 2026, maintaining RHEL packages and contributing to ea-nginx. Master's in Computer Science. I run GetPageSpeed, a commercial RPM repository powering high-performance web stacks across enterprise environments. What I deliver: PERFORMANCE & CACHING - NGINX and Varnish configurations that cut TTFB below 200ms - Full-page cache architecture: cleanly separating cacheable public pages from personalized content like login state, carts and chat - CDN and Cloudflare setup that actually serves from the edge instead of hammering your origin - PHP-FPM, Redis and OPcache tuning for maximum throughput - MySQL/MariaDB optimization that removes the bottleneck instead of hiding it - Core Web Vitals and PageSpeed scores from 20 to 90+ CLOUD & MIGRATION - AWS architecture and zero-downtime migrations off shared or managed hosting - Properly separated production, staging and satellite applications - Docker, GCP, Azure, DigitalOcean SECURITY - Malware removal and full hack recovery - Firewall hardening (UFW, fail2ban, ModSecurity) - SSL/TLS with A+ ratings - Vulnerability patching and incident response TURNKEY SERVER SETUPS Laravel, WordPress/WooCommerce and Magento 2. From 5 hours, with zero downtime. What makes this different: every server I build gets access to my private RPM repository. Enterprise-grade prebuilt packages with one-command upgrades. It's like NGINX Plus, but better, and with a lifetime license. Stack: Linux (Ubuntu, RHEL, AlmaLinux, Rocky, Debian) | NGINX | Varnish | Cloudflare | Redis | Docker | AWS | GCP | Azure | DigitalOcean | PHP-FPM | Laravel | MySQL | MariaDB | PostgreSQL I work via SSH. No plugins, no bloat. Server engineering done right.
