Oleksandr Herasymchuk

Mobile-Native AI Engineer

From optimizing mobile experiences to architecting intelligent systems

$ whoami

A software engineer with deep mobile roots, now building intelligent systems. Bridging performance-critical development with practical AI solutions.

I build software that solves real problems. Starting from mobile development where every millisecond and byte matters, I now design systems that make technology work better for people without the complexity showing.

Based in Portugal through OLEKSANDR HERASYMCHUK, UNIPESSOAL, LDA, I transform complex technical challenges into elegant, performant solutions.

Evolution Path:

Mobile-Native Development → AI Systems Architecture
Performance-Critical Code → Resource-Efficient AI Models
Real-Time Mobile Apps → Intelligent Data Processing
Hardware Constraints → Deployment Optimization
User-Centric Design → Human-AI Interfaces
