About Me

Flight dispatcher with 12+ years in civil aviation and an MBA in AI for Business. I build full-stack solutions using AI to boost productivity.

Before aviation, I lived and worked in Japan for three years — an experience that taught me adaptability, discipline and how to solve problems in entirely new environments. In aviation, I work with complex systems, real-time data and critical decisions under pressure. I saw problems that technology could solve — and started building the solutions myself.

I don't have a formal background in programming — and that's the point. I identify the problem, design the architecture and use AI as a coding copilot. I apply this approach to web and Android applications, smart-glasses integrations and automations. The portfolio includes an app published on Google Play and projects in beta testing.

How I Build

My approach: I lead the process, AI speeds up execution.

Problem I identify the real need
Architecture I define the structure, stack and logic
AI & Integration I implement with AI and connect APIs
Testing I validate, fix and refine
Deployment I publish validated versions
MaintenanceMonitor, fix and improve

Integration is part of implementation: APIs, authentication and device communication. Validation includes automated checks and physical testing when hardware is involved. Maintenance follows each release.

I don't ask AI to “make a website.” I define what to build, how and why — and use AI to speed up coding. The domain expertise, product vision and decisions are mine.

Projects

Built from scratch with AI as a productivity tool.

Featured Project

Flight Ops Log

A platform supporting flight dispatch operations. I designed the entire architecture and business logic based on my aviation experience, using AI to accelerate implementation. It integrates real-time weather (METAR, TAF, SIGWX), MEL/CDL analysis via Ollama, an interactive route map with Leaflet, ATS message generation and AI-generated NOTAM summaries.

My contribution: I designed the architecture and domain logic to bring weather, route planning and dispatch information into one workflow.
