About Me
I’m a Software Engineer and Flutter Developer with over 3 years of experience building high-performance, cross-platform mobile applications for iOS and Android — and I’m now deeply focused on AI Automation and intelligent systems.
My core strength is combining solid software engineering principles with modern AI and automation tools. Unlike typical “no-code” implementers, I design robust, maintainable systems using Python, FastAPI, structured JSON, and workflow orchestration tools like n8n.
I’ve delivered multiple apps to the App Store and Google Play, built MVPs from scratch, and scaled production systems for startups, NGOs, and enterprises. I care deeply about clean code, performance, reliability, and user experience — whether I’m building a mobile app or an AI-powered backend.
