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.
