Flutter • Game Systems • Offline-First • AI Agents • OSS
I build systems, not one-off apps.
My work lives at the intersection of mobile engineering, game mechanics, and AI-assisted workflows — focused on products that are modular, offline-capable, and designed to scale across real-world constraints.
This profile is a living archive of experiments, frameworks, and production-ready tooling under the fifty.dev ecosystem.
- Flutter Engineer building cross-platform mobile experiences
- Builder of offline-first, real-time, and game-driven systems
- Heavy focus on architecture, tooling, and developer velocity
- Currently shaping an ecosystem around AI agents + dev automation
I don't chase trends — I design foundations.
"If it can't be reused, automated, or evolved — it's not done."
Core principles:
- Modular over monolithic
- Offline-first by default
- Declarative > imperative
- Tools should feel like teammates
- Code is a product, not just implementation
A comprehensive Flutter/Dart toolkit extracted from production apps:
| Package | Description |
|---|---|
| fifty_audio_engine | Audio playback & recording (BGM/SFX separation) |
| fifty_speech_engine | Text-to-speech and speech-to-text |
| fifty_sentences_engine | Sentence building & word bank systems |
| fifty_map_engine | Cross-platform maps integration |
| fifty_printing_engine | ESC/POS printing (Bluetooth & WiFi) |
| fifty_cache | Multi-tier caching with TTL support |
| fifty_storage | Key-value storage abstraction |
| fifty_connectivity | Network monitoring + offline detection |
| fifty_tokens | Design tokens (colors, typography, spacing) |
| fifty_theme | Theme generation and management |
| fifty_ui | Component library (buttons, cards, inputs) |
| fifty_utils | DateTime, responsive design, API state |
Plus:
- MVVM + Actions template — Full app scaffold with GetX
- Demo app — Showcases all packages
Built to be documented, tested, and extended.
igris-ai — AI Engineering Platform: From Vibe Coding to Vibe Engineering
An AI persona/agent layer that supports:
- Multi-agent orchestration (18 native subagents)
- Brief management & session recovery
- Architecture enforcement & quality gates
- Code generation workflows
Think AI as infrastructure, not a feature.
| Repo | Description |
|---|---|
| fifty_map_engine | Interactive map rendering |
| fifty_sentences_engine | Word/sentence game mechanics |
| fifty_speech_engine | Voice-driven gameplay |
| flame-2d-game | 2D game with Flame engine |
| graph_builder | Graph/node-based systems (C++) |
Games are just apps with stricter rules.
Many packages are designed for:
- Limited connectivity (
fifty_connectivity) - Local storage (
fifty_storage,fifty_cache) - Multi-tier caching with TTL
- Long-running reliability
Because the real world isn't always online.
Mobile
- Flutter (GetX primary)
- Custom MVVM + Actions architecture
- SQLite, GetStorage
- Flame Engine, CustomPainter
Audio / Media
- Custom audio abstraction (
fifty_audio_engine) - TTS / STT pipelines (
fifty_speech_engine)
Infra & Tooling
- REST, WebSockets
- Firebase (Auth, FCM, Distribution)
- CI/CD (Fastlane, Codemagic)
- ESC/POS printing
AI / Automation
- Agent-based workflows (IGRIS)
- Prompt-driven tooling
- CLI-first thinking
Not everything here is "finished" — and that's intentional.
You'll find:
- Production-ready packages
- Extracted engines
- Experiments
- Forks and contributions
Some projects are weapons, some are prototypes, all are learning artifacts.
- A cohesive fifty.dev open-source ecosystem
- AI agents that feel like senior teammates
- Developer tools that remove friction, not add abstraction
- Systems that survive scale, chaos, and time
If you're here looking for:
- Clean abstractions
- Thoughtful architecture
- Systems thinking
- Or just inspiration
You're in the right place.
Build once. Extract forever.
