**Programming ‍ → 5+ years of experience**
I’m proficient in TypeScript and various frontend (React, Remix, NextJS) and backend frameworks (NestJS, Express). I’m a big fan of everything related to Developer Experience, Cloud Solutions (AWS), and generative AI.

I have strong experience with everything related to React & React-Native (AWS Amplify, Google Firebase, CSS-in-JS, Tailwind CSS, React-Query, MobX, and Storybook - to name a few).

**Team Leadership  → 3+ years of experience**
Since 2021 I have led the in-house JavaScript Team consisting of 7 developers. I was responsible for managing the planning, product architecture & development, code & peer reviews, HR, and mentorship.

**Product Ownership  → 3+ years of experience**
I consider myself as a “creative” as much as a technical person. During my lengthy period at TDSOFT (my current employer), I have also had the pleasure to lead the Research & Development department and produce products and concepts. Most notably:

- betsense.ai (2023) - B2B & B2C SaaS app leveraging AI to produce quality sports betting content (match analysis, predictions, etc.).
- bettorsignals.com (2022) - Affiliate sports tipping website for bettors.
- tournamently.io (2022) - Concept of a gamification tool to be used by sports media companies for big sports events.

**Entrepreneurship  → 10+ years of experience**
I have always had a mind focused on entrepreneurship, which resulted in many businesses I ran while I was still at school. I’m very proud of my doing in all those years.

- afflite (2020 - Present) - Small network of affiliate & media pages.
- SkinMarket.pl (2015 - 2018) - E-Commerce selling CS:GO in-game skins for +150k customers.
- Fortuna-Gier.pl (2014 - 2015) - E-Commerce shop with CD-Keys.
- 3Mod.pl (2010 - 2014) - Forum for gamers & network of public game servers

**SEO  → 3+ years of experience**
Since 2020 I got into affiliate marketing starting with pages such as m1displays.com and as a result, I started learning SEO. I’m running my own affiliate pages in English, Polish, and Ukrainian that serve content for ~20k users monthly.
