About Me

Developer who ships products

I am Nik, a Senior Mobile & AI Architect with a decade-long track record of engineering high-performance applications for millions of users worldwide.

Unlike a typical developer-for-hire, I am a Product Strategist. Having founded Inflixo AI — a live OTT ecosystem for the creator economy — I bring a founder’s mindset to every project, ensuring technical excellence aligns with business goals.

My journey includes a 4+ year partnership with US-based SaaS leader Time Clock Wizard, and core contributions to global platforms like Credit Karma and ConfirmTkt. I specialize in architecting secure, scalable solutions across Fintech, SaaS, and AI-driven automation.
