While having a mostly C++ background, I want to expand my skillset. In particular I'm interested in Big Data with Scala and machine learning with Python, but open to other opportunities (although not a fan of front-end development). Here's where I worked in the past: Backend Developer (Python) (September 2019 - November 2019): - Lead a 4-people team of front- and back-end developers - Oversaw development across all layers from database design to REST API specification - Designed an onion-based application architecture using DDD principles Technology stack included: Swagger, SQLAlchemy, PostgreSQL, SQLite, Docker, Angular. C++ Developer (June 2019 - September 2019): - Resolved binary interface compatibility issues - Implemented gathering hardware information for geolocation - Fixed bugs in a multithreaded application C++ Developer (November 2018 - June 2019): - Optimized high throughput code for performance - Used profiling tools to measure performance and detect bottlenecks - Written scripts to streamline the workflow for both myself and the team - Actively sought work process improvements - Rewrote the build system using CMake C++ Developer (July 2016 - October 2018): - Designed and implemented core algorithms and models - Provided memory and performance efficient solutions - Thoroughly covered implementation with unit and component tests - Generated feature specifications by researching the industry domain - Routinely discussed specifications with domain experts to provide the best solution - Constantly sought improvements to the product - Closely collaborated with other developers on solving architectural challenges - Coached interns into junior employees

Linux, Git, SQL, Docker, OOP, Python, Scrum, REST API, C++, Ruby

In 3 years I have worked on projects from various domains and used different tools. Some of the tasks include: - Designing application architectures - Leading a team of developers - Coaching interns into full-time employees - Designing and implementing core algorithms and modules - Verifying functionality by writing unit, integration and acceptance tests - Writing tools to assist me and my team in day-to-day tasks I am able to pick up new technologies and get into new domains in a short amount of time. Recently I made a switch from writing desktop applications and utility libraries in C++ to developing web services in Python. After only a couple of weeks I felt comfortable enough to lead a team with more experience with that specific technology than me.

What I like: - Small companies with family-like teams - Interesting projects with lots of work ahead - Skilled coworkers - Streamlined work processes What I don't like: - Restrictions in tools choice - Unmaintainable codebase - Bureaucracy
