Fillip Mangia

I'm an english fluent Frontend Developer with hands-on experience building and owning complex iGaming and fintech platforms. At Playsoft, I took sole ownership of Playfiver, a live gaming API platform, delivering the user-facing dashboard, admin panel, and mobile apps end-to-end. I thrive in full-spectrum development roles: equally comfortable engineering polished UI/UX features, integrating third-party APIs, contributing to back-end logic, and shipping native mobile apps.

I bring the proactive mindset and adaptability your team needs
