I write mobile software from Heraklion, Crete. Mostly Android and Flutter; sometimes Swift when a small macOS utility gets out of hand.

Small apps, practical tools, and the occasional over-engineered fix for an annoying workflow.

Find me on my site, LinkedIn, or pub.dev.

• Peakward — Running coach in beta with HealthKit sync, adaptive training plans, and a small Postgres/PostgREST/Deno backend. (App Store pending approval, Play Store pending approval)
• Healpen — Private expressive-writing journal based on Pennebaker’s method, with encrypted local storage and mood trends. (App Store pending approval, Play Store pending approval)
• Mighty — Small macOS menu bar utility for Logitech mice, built with SwiftUI and HID++.
• efimeries — On-call scheduling PWA for Greek public-hospital doctors, with a constraint solver under the hood.

• famon — Dart CLI for watching Firebase Analytics events from Android and iOS logs. Published under the mikezamayias.com pub.dev publisher.
• mikezamayias.com — Personal site and contact platform built with Nuxt, Firebase, CI smoke tests, and Lighthouse checks.

• Budget Coach — Envelope budgeting app with offline-first local storage and sync experiments.
• LocalMind — On-device AI/RAG prototype using Flutter, ObjectBox, llama.cpp, and whisper.cpp.

• Production Android work across multi-app retail mobile products.
• Flutter work across onboarding, payments, referrals, retention, Firebase functions, and release automation.
• I like mobile UI, analytics instrumentation, CI/CD, accessibility tooling, and code that is boring in the right places.
