AI-Native Software Engineer at AirPlx · Fullstack, Mobile & Cloud

Remote · Open to relocation

I am a Software Engineer at AirPlx, where I build product with the team across the web platform and the iOS/Android app that aviation crews use on the ramp every day.

My edge is engineering experience multiplied by AI. Years of building production software taught me architecture, debugging and what good code looks like; AI lets me apply that across the whole stack (web, mobile, backend, databases) and move fast in any technology. AI is the multiplier, engineering judgment is the base: I own the design, the review and everything that reaches production.

Before AirPlx, I was a Top Rated freelancer on Upwork with a 100% Job Success Score (top 10% of global talent), delivering production apps, APIs and AI integrations for clients worldwide. I work daily in English (B2) with US-based teams.
