Tomáš Krčál
Software Engineer
Hi, I’m Tomáš — a senior full-stack developer and DevOps engineer with 8+ years of experience building scalable applications, managing complex cloud infrastructure, and designing complete end-to-end digital products.
My programming journey started back in high school, where I quickly discovered my passion for technology. I taught myself PHP and JavaScript, and soon expanded into modern frontend frameworks like ReactJS, NextJS, VueJS, and React Native. Over time, I grew my backend skills with Node.js, Laravel, MySQL, and MongoDB.
After co-founding GeekCoders, a digital agency, I naturally stepped into infrastructure and DevOps — building Docker images, automating CI/CD pipelines, and orchestrating deployments. This hands-on experience led me deeper into Kubernetes, where I earned my certification and began managing cloud-native environments across AWS and DigitalOcean.
Later, I joined Mall.cz, gaining deep experience running production Kubernetes workloads at scale. After Mall.cz became part of the Allegro Group, I contributed to the platform migration of CZC.CZ and MALL.CZ into Allegro’s ecosystem.
Currently, I’m working with the GeekCoders, DeepVision and DeepGaming group, where I independently manage and maintain multiple Kubernetes clusters (around 5 active clusters), acting as a solo DevOps engineer. I design and maintain infrastructure that empowers developers to focus on shipping code — providing:
• Helm charts for streamlined application deployment.
• Base PHP, Node.js, and frontend Docker images.
• Stateless application architecture design.
• Infrastructure consulting: helping teams choose the right technologies for the right use-cases (e.g. RabbitMQ for messaging, Redis or KeyDB for sessions, etc).
• Security services like Consul, Vault, and secret management.
• Hybrid workflows combining managed VPS with Kubernetes integrations.
• Custom integrations like managed analytics stacks (Redash, ClickHouse, etc).
In parallel, I’ve also pursued my passion for solo projects — building apps and games such as Cat Conquest, Rotspire, and QuizRaid, where I blend my full-stack and infrastructure knowledge to deliver full products end-to-end. I even picked up SwiftUI in just one month to create my own native mobile apps.
Beyond work, I enjoy catching a beer with friends, playing guitar, gaming, and spending time with my three cats. I love working on projects that make sense, create real value, and help my customers succeed.
