Genadiy R.

I'm a Senior Full-Stack Developer with 30+ years of software development experience, specializing in web and mobile applications, AI integrations, business automation, APIs, and custom internal systems, as well as Google Workspace & Google Sheets automation.

I help businesses automate their workflows, connect different systems into one ecosystem, and build custom software that saves time. If you need a web platform, a mobile app, an AI-powered assistant, or complex integrations between multiple services, I build solutions that are scalable and designed for long-term growth. A lot of my work also focuses on building practical solutions using APIs, Google Sheets (Google Apps Script), and AI tools.

What I build:
Full-stack web applications
Business automation platforms
Automating business workflows
AI-based tools (ChatGPT, OpenAI, Whisper, AI Agents, etc.)
API integrations for connecting APIs between different platforms
SaaS products, web applications, and backend systems
CRM & ERP integrations
Internal business systems and admin panels
Admin dashboards, reporting & analytics systems
Mobile applications (Flutter, AppSheet)

I've built integrations with platforms including:

I prefer simple, safe solutions that solve real business problems. In most cases, I choose custom development over no-code tools because it gives more flexibility and long-term stability.

• Full-stack web development
