Batumi, Georgia - 3:16 am local time
I help businesses automate their workflows, connect different systems into one ecosystem, and build custom software that saves time.

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

Whether 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, 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, AppSheets)
Google Workspace & Google Sheets automation
E-commerce integrations

Frontend: React, Next.js, JavaScript, TypeScript, HTML, CSS
Backend: Node.js, Python, PHP, Google Apps Script
Databases: MySQL, PostgreSQL, SQL Server, MongoDB, Firebase
Cloud & APIs: REST APIs, GraphQL, OAuth, Webhooks, Google Cloud, AWS
AI: OpenAI API, ChatGPT integrations, AI assistants, LLM-based workflows, speech-to-text solutions (Whisper)

I've built integrations with platforms including:
Shopify • Stripe • QuickBooks • HubSpot • Salesforce • GoHighLevel • Zoho • Twilio • Meta/Facebook • Google Workspace • Trello • Pipedrive • Mailchimp • Telegram • WhatsApp • Airtable • Notion • and many others.

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.

I'm available for both short-term projects and long-term partnerships involving:
• Full-stack web development
• Business process automation
• AI implementation
• API integrations
• SaaS development
• Mobile applications
• System architecture
• Internal business platforms
