Rust - My go-to language for most projects. Very little downside.
Python - For faster iteration, and quick scripting.
Javascript / HTML / CSS - For frontend (or full-stack) web development, as well as any scripting requiring easier concurrency. Web frameworks wise, I have professional experience with React, and personal experience with Svelte and Vue, but my preference is usually to go vanilla unless a framework is actually necessary.
Cloud Platforms - Most experience through AWS. You may eventually outgrow it, but until then it's often worth it.
PostgreSQL - The database engine which I've had the most pleasure working with.
Unix - No flavour in particular. Mostly used MacOS professionally.
Git - Used throughout my career with no complaints. Preferred platform (if not distributed) is GitHub.

Go - Confident with the language, having used it in a professional setting for several projects (at Checkit).
Kotlin - Limited experience through Android app development (at Ipsos), but that wasn't my primary area of focus.
Ruby - Not used professionally, but its strong community sells it as a good language to work with.

Java - Used professionally at Ipsos. First language used in a formal setting (IB Computer Science course).
C++ - Developed and maintained low-level (high performance) audio processing algorithms at Ipsos.
PHP - Used professionally at Ipsos, and one of the first languages I learned as a teenager.
MySQL, SQLite - Used extensively at Ipsos.
MongoDB - Used professionally at both Checkit and Ipsos.
Jenkins - Used throughout my career, until Ipsos migrated to GitHub.
Jira, BitBucket, Confluence - Used at both Checkit and Ipsos.

Self-taught programming at an early age by taking an interest in game development and modding.
Frequently needed to rapidly adapt to thrive in high-pressure environments.

Transparency is at the core of my values, striving to build a team-wide feeling of product and process ownership.
As a naturally empathetic person, I aim to foster a healthy, inclusive, and supportive working environment.
Learned many valuable, transferable leadership and organisational skills as a team captain and coach.

Experience as a teaching assistant, as a student supervisor, and even as a coach has taught me to communicate information clearly, effectively, and appropriately for a variety of target audiences.
Have frequently presented products being developed to non-technical audiences of investors and other stakeholders.

The sport has been my primary hobby since 2014, and still takes up the majority of my free time.
Competed at the European Championships multiple times.
Most of my annual leave will be used travelling for tournaments.
