👨‍💻 My journey into the world of creation began with a set of Legos when I was just 5 years old. That early fascination with building has evolved into a lifelong passion for development and innovation.

I take great joy in supporting others to achieve their goals, which has naturally led me to become proficient in people management. My work focuses on crafting applications that combine aesthetic beauty with high performance, reliability, and user-friendliness—and I do so with efficiency. My intrigue with emerging technologies like LLMs and Generative AI has recently driven me to develop groundbreaking applications powered by these advancements.

With a background in authorship, I’m adept at producing clear technical documentation, ensuring my teams have the resources they need to excel. I frequently lead product management efforts, gathering and analyzing business requirements and liaising with stakeholders to bring projects to fruition.

Building diverse teams is a cornerstone of my philosophy, as I believe varied perspectives foster stronger products. By nurturing a culture of psychological safety, I maintain team morale at exceptional levels, resulting in remarkable productivity, unwavering customer focus, and collective pride in our achievements.

During my tenure at Allegro, I expanded my knowledge in cross-browser compatibility, responsive web design, and single-page applications, while deepening my expertise in observability and on-call workflows. I managed Allegro's web advertising SDK, integrating our API across various platforms. I designed multiple data analytics platforms from the ground up, strengthening my insights into adtech and big data.

At Temu, I delved into the world of micro-frontends using module federation, further enriching my technical toolkit with GraphQL and Java web services expertise.

My time at ELEKS provided substantial exposure to freight, fintech, and logistics, where I pioneered a white-labeling solution.
