Hi, I am

Aleksandra
Pytko-Włodarczyk

I am a Marketing Core Lead.

about me

I translate the complex world of software engineering into compelling B2B narratives. In the high-growth tech space, building a great product is one thing, but the real challenge is telling its story in a way that resonates with the market. At Callstack, I act as the bridge between our developers, sales teams, and the audience. I take raw technical insights and transform them into high-impact content, from deep-dive blog posts to global webinars and ebooks.

ENGINEERING ORDER FROM COMPLEXITY

I believe that for creativity to scale, it needs a foundation of meticulous order. I thrive in the engine room of marketing, where I specialize in building the systems that allow high-volume production to run like clockwork. Whether I am managing the website roadmap, leading the organization-wide Brand Consistency project, or coordinating a 10-person crew in a live conference studio, I am at my best when juggling multiple priorities and cross-functional teams.

DRIVEN BY PROCESS, PROVEN BY RESULTS

Audience growth

I orchestrate the end-to-end production and rebranding of the React Universe On Air podcast, resulting in a +371% audience growth in 2025.

System architecture

I engineer a centralized source of Truth in Notion, authoring 70+ pages of documentation and workflows that streamlined team onboarding and knowledge sharing.

Operational scale

I manage the pipeline for a cross-functional team of five, delivering a consistent, high-volume monthly output of blog posts, live streams, video tutorials, and webinars without compromising on brand integrity.

Brand authority

I oversee the development of asset libraries and core templates, ensuring 100% brand alignment across every department in the organization.

AFTER HOURS

While I spend my days building scalable marketing machines, I’m a creative at heart. My background in English Philology, and a once-upon-a-time PhD path in Shakespeare still colors my professional world; I believe a well-placed metaphor is often as powerful as a well-optimized process.

After hours, you’ll find me .with a watercolor brush in hand, working on an embroidery project, or lost in a book. I live in Poznań with my husband (the developer who built this site, thank you!) and our very spoiled, very fluffy cat.
