Antonin's consultancy endeavor. Served in various positions on different projects. They typically encompass Engineering leadership with machine learning or high-scale distributed systems. Some highlights:- since May 2021 -- Mayadata -- Advisor- Oct 2020 - Apr 2021 -- Mayadata -- VP of Engineering (VPE) and Principal Engineer (MayaData is a leading CNCF container attached storage provider).- 2020 -- MoistureGuard -- CTO (Formed an engineering team, designed IoT plaform for wooden buildings moisture measurement, implemented sw for acquisition gateways.)- Jun 2019 - Jul 2020 -- DTOne -- CTO Data Plaform (DT One operates a global network for mobile top-up, rewards/incentives and airtime credit solutions.)

I serve as an advisor, helping to make choices about strategy, and mediating between key people.Recombee is a content recommendation engine, which we use at ShowMax. The generic approach of Recombee lets it be used in a limitless number of use cases, like jobs listings, publishing, or online video streaming.

I kept an eye on the overall architecture, helping others understand, operate and extend the platform. I was responsible at both the technical and human levels. I’m always looking for what’s coming next so we can keep ahead and choose our path wisely.I directly managed the team of engineering team leaders. We have grown from 8 to 100+ people within last 3 years.Our platform was developed completely in-house, and we are capable of delivering on demand video streaming around the world. I have chosen microservices as the way to go from the very beginning (2013), we ended up with 150+ different services running in more then 1100 containers. Internal logging and even processing infrastructure was crunching over 4 billion events every day. We also built own encoding platform and CDN for content distribution across Africa. Encoding platform is capable of h.264, h.265 (HEVC), VP9 and has experimental support for AV1.I navigated Showmax through IPO (un-bundling) process. This resulted in Showmax being part of newly created MultiChoice Group (MCG) listing on Johannesburg Stock Exchange.

I have build the engineering team from scratch and defined the architecture. It was service oriented from the very beginning. Microservice approach allowed for rapid implementation and scaling. I've also wrote initial code for many microservices. This work became foundation for Showmax.

Defined a company vision and strategy. Designed a distributed, high-scalable and fault tolerant platform for IPTV and VoD Services delivery. Led preparations of customized solutions. Supervised and defined the corporate processes. Defined corporation business strategies. Led development and implementation team. nangu.TV platform is based on work of ITonis Inc.

Participated in the "Joined Czech Group" at BNL. Contributed to the PHENIX experiment by troubleshooting and tuning of the computational cluster management system (based on Condor) and vxWorks-based event catchers. Proposed optimizations of data processing and management in RIKEN, which were lated put into production.

Participated in the COMPASS experiment on the Central Data Recording (CDR) team - the crucial part of the data processing pipe-line using distributed multi-petabyte storage. Designed and implemented a new job submission system for hadron data production. Committed several improvements to the on-line monitoring system (COOOL).

Technical Director (CTO) and lead developer. We have coined term TV Everwhere and built one of the first platforms for storing live channels and making them available over Internet (basically network PVR service). To be able to achieve that, I've designed "stream cluster filesystem" for storing time-unbounded video streams in storage cluster built from commodity hardware.We have pivoted towards building IPTV platforms for telcos, which resulted in nangu.TV.(Xeris was renamed to ITonis)

I have been appointed as member of board of experts for KIVS infractructure (Communication Infrastructure for Public Administration) at Ministry of Informatics Czech Republic (MICR). I have been appointed as member of board of experts for IDAbc infractructure at Ministry of Informatics Czech Republic.
