Denys Pupin
Software Engineer
Hi 👋🏻. I'm a software engineer with 8+ years of experience building products in different industries. I enjoy working through complex challenges with people who care about the outcome, then turning that work into something real and useful. Whether it’s scaling backend systems or fine-tuning UX details, I like connecting the dots between tech and business.

Experience
Software Engineer
Commerzbank AG
I help ship HR features without the usual corporate sadness: thoughtful UX, accessibility by default, and integrations that actually hold up (SAP + data hub). I tend to take initiative - getting people aligned, raising the bar on component design and testing, and turning “we should” into “it’s done”. I also spend time on architecture and technical strategy, because you deserve better future.
Senior Full-Stack Developer
Keystone Education Group AB
I worked on a high‑traffic education marketplace where performance is product: better Core Web Vitals, cleaner UX, fewer “why is this slow?” moments. I also helped start a university-facing portal with architecture, domain model, and documentation that let the team ship without lore. Sanity + GrowthBook rounded it out: content that publishes reliably and experiments that teach us something.
Software Developer & Consultant
MDriven AB
I worked across products, shaping features and UX with a strong bias for consistency. I designed and implemented an Angular UI component library that enabled teams to build and customize their own solutions on top. Behind the scenes, I refactored and optimized legacy areas to improve maintainability and performance, backed by clear technical documentation and active mentoring of junior developers.
