"Upstart commerce" is a startup company offering a headless e-commerce platform, a set of backend services providing APIs for various e-commerce needs. Big features, small bugs, production support, customer issues—you have to do it all in a small company. Besides that, we're slowly moving towards reimplementing most of the key services in a pure FP, ZIO-based architecture.PL: Scala

I was leading a "Data Connectors" team working on providing connectivity to different data sources, normalizing the schema and extracting data for analytical purposes; targeting a wide range of data sources, like relational databases (MSSQL, MySQL, Postgres, etc.), file-based (CSV, Excel files), analytical databases and warehouses (Redshift, Google BigQuery, Snowflake), web services and social networks (Facebook, Twitter, Stripe, Hubspot, etc.) and many more. We used Scala for all of our projects with a high emphasis on functional programming. I've put a lot of effort into mentoring newcomers with OOP background to help them make the switch and educate other people about the benefits of FP.PL: Mostly Scala, a bit of Java and C#, targeting Windows and Linux with Kubernetes orchestration.

Joined the company to design and implement an ETL infrastructure for connecting to various data sources and bring data into our proprietary data warehouse. The new framework design had to support multiple run time environments, be scalable, extendable and provide an SDK for 3rd party connectors development. It was implemented on JVM using Scala (the one I was leading) and on .NET using C#. The performance was vital, so it was quite an interesting and challenging experience designing a purely functional system that would perform as fast as an imperative version.PL: Scala and C#

Teramind is a startup company specializing in website and application monitoring, file tracking, network capture, session recording, and activity analysis. I was leading the OS X development branch of the project, ensuring that all features are aligned across platforms with the same quality level. Designed and implemented kernel extensions for darwin kernel that had to:- Control filesystem authentication: monitor or block folder activity, external drives mounting, network shares connections, cloud drives uploads/downloads- Filter network TCP/UDP packets. Receive, decode and parse application layer protocols like HTTP, SMTP, pop3, TLS/SSL, etc. and eventually make a decision based on the packet's content.PL: C++ for application code and C for kernel extensions, targeting OS X

Playtech's Poker department develops an online poker platform. I was responsible for unifying multiple (platform-dependent) codebases under one solution that would simplify the app's development, deployment, and maintenance. That involved porting existing functionality from iOS to Windows and Mac and vise versa. There were a lot of technical challenges that required deep knowledge of various low-level components and compilers.PL: Mostly C++

"Videobet" develops gaming terminals platform and casino management system. It was hosted on specific hardware, which posed a lot of interesting challenges. I mostly worked on the core functionality, game engine, tooling, testing automation, and infrastructure.PL: C++ and C# targeting Windows Embedded
