About Tomas Voslar

I thrive on tackling complex problems end-to-end, from client development for mobile and web to distributed backend systems with infrastructure in Kubernetes. My experience spans working in large companies like Outreach and Microsoft, where I solved challenges such as implementing GraphQL in distributed systems with hundreds of developers.However, my true passion lies in the startup world, where I enjoy building systems from scratch, leading development teams, and helping developers grow. I am excited by the opportunities to innovate, drive growth, and make a significant impact in dynamic, fast-paced environments.

  • Sport Buddy
    Co-Founder
    Sport Buddy May 2018 - Present
    We started Sport Buddy with my ex colleague from Microsoft, because we both have passion for Ice Hockey and we lacked tool which would allow us to manage hobby hockeys. This is our pet project, which on we are working in our free time or between projects.I always used this project to try out and learn new things, for example it was my first Kubernetes cluster, first React Native mobile app or first steps with GraphQL here on this project. Therefore I found this project extremely useful in my career, because not every time we have chance to touch technologies we are interested in. I was able to convince other people on other projects to use these technologies as it's extremely accelerate development time, removes holes between Backend and Frontend teams and makes code maintainable into the future.

  • #Beapp
    Software Engineer
    #Beapp Oct 2019 - May 2021
    I was asked to join as a first developer in new startup called BeApp, to architect the whole system. We started with mobile application for iOS and Android written in React Native (using TypeScript, apollo client for GraphQL, styled-components etc...), for that we also needed backend which is GraphQL API in Node.js also written in TypeScript, using MongoDB, Redis databases. This backend system runs in Kubernetes cluster, which was deployed to AWS (used Kops). We also had to develop two web applications, one is a web version of our mobile app and second is back office for administration.It was very interesting experience as I was able to touch product from the server infrastructure in Kubernetes to mobile and web clients. I was responsible not only for programming, but also for leading other developers, who joined us throughout this project.

    Prague, The Capital, Czech Republic
    First two months I have been working as a PHP developer, we had a task to improve source code of one middle sized application for internal statistics. After a code review we have decided to completely rewrite this application to SOA, backend was in Symfony+Doctrine and frontend part was in Angular. Despite small size of the team we were following scrum methodology, focusing on high quality code (well documented and tested with more than 90% of code coverage). We were able to deliver on time, with all goals completed.After this short term project I was assigned as a Team leader to nodejs project, which was about creating application for information systems into trains. My predecessors picked very interesting approach for this problem and it was a pleasure to continue with technologies such as ZeroMQ, WebSockets and others. Equally interesting was again Scrum methodology, which was very strictly followed up, it was like reading a book about Scrum in real life!
