George Burduhos

Cross-Platform
Engineer.

Mobile · Web · AI Integration

16+ years shipping mobile products — React Native, Expo, iOS, Android. One codebase across all platforms: native apps, web, and PWAs from a single TypeScript source. Delivered in fintech, blockchain, media, and enterprise.

Full-stack capable — TypeScript, Node.js, REST APIs, CI/CD — and hands-on with LLM integration: Claude, OpenAI, streaming APIs, on-device inference. AI where it earns its place, not as a feature flag.

Currently building two AI-native apps in production — StatsOS and DayOS.

AI & LLM Integration

AI as a tool, not a headline.

Over the past two years I've worked hands-on with LLM APIs and AI-assisted tooling — integrating them into mobile products and engineering workflows where they genuinely add value. I'm comfortable owning this layer end-to-end alongside the mobile work.

API integration

Connecting LLMs (Claude, GPT-4, Gemini) to mobile apps — chat interfaces, content generation, smart search, contextual suggestions.

Workflow automation

Using AI to automate repetitive engineering tasks: PR reviews, release notes, CI/CD decisions, test generation.

On-device & edge

Integrating on-device ML models and edge inference for features that need to work offline or with low latency.

Practical, not hype

I add AI where it genuinely solves a problem — not as a feature checkbox. The product comes first.

Experience

16 years in mobile development.

Most of my client work since 2023 comes through a long-term agency partnership. The projects are under NDA, but the scope, stack, and outcomes are available to discuss directly. Reach out if you'd like details.
