1000 USD OquLab IDE — Mobile development environment and Raptor interpreter
App Development for Android
I designed and developed from scratch a unique mobile development environment (IDE) for Android and an embedded interpreter for the open-source programming language Raptor Lang. The language features a modern Kotlin-like syntax with full support for keywords in Kazakh and English — this is an innovative educational and tool project. Key results and features that I implemented independently:
Custom QWERTY keyboard for Android with modifiers, navigation arrows, and quick input of special characters — specifically for comfortable coding from a smartphone.
100% offline code validation, sandbox (REPL terminal), and local execution system.
Interactive lesson module with Markdown rendering, gamification, XP system, and achievements.
… Engine for automatic testing of algorithmic tasks (over 140 challenges).
Complete web infrastructure: official website oqulab.kz with advanced SEO (Schema.org + JSON-LD).
Organization of app distribution on Google Play and publication of the Raptor Lang source code on GitHub.
Development methodology: AI-Driven Architecture + Vibe Coding. I actively directed and coordinated the work of AI assistants (Claude Code, Gemini, Codex) to solve both low-level tasks (parsing syntax, processing AST trees) and product features.
Technology stack: Android SDK, Kotlin/Java, ANTLR / Compiler Design, Git, HTML5/CSS3/JS (landing page).
The project demonstrates deep experience in creating complex mobile tools, compilers/interpreters, and educational platforms from scratch.
Key skills and categories (for the form):
Kotlin, Android SDK, Jetpack Compose, ANTLR, Compiler Design, MVVM, Coroutines, Git, UI/UX (Figma → Code), Server-Driven approaches, AI-assisted development, Educational applications, Programming language interpreters.

3000 USD QuadKings — Cross-platform chess game for 4 players
Hybrid Mobile Apps
I founded the studio RoboForgeStudios and independently developed and launched a commercial cross-platform gaming project — a unique chess variation for 4 players with simultaneous moves and fog of war (Fog of Checkmate). The game has been successfully published on Steam and Google Play. What was done from idea to release: Designing and implementing a client-server architecture in Kotlin (Coroutines, Ktor Client/Server) with stable real-time multiplayer. A global matchmaking system, custom lobbies, a ranking system according to FIDE standards, and dynamic leaderboards. Designing relational databases for storing game sessions, rankings, and user profiles; optimizing SQL queries for high-load operations. Product mechanics: alliances, in-game cosmetic shop, integration of analytics systems and AI components. Fully adaptive UI/UX (from Figma to code) for a seamless experience on both PC (Steam) and mobile devices (Android). Self-publishing on Google Play and Steam. Result: A complete development cycle of a commercial product from scratch, including backend, real-time networking, game design, monetization, and release on two platforms. Key skills and categories (for the form): Kotlin, Android SDK, Jetpack Compose, Ktor (Client/Server), Coroutines, MVVM, Client-Server Architecture, Databases (SQL), Realtime Multiplayer, UI/UX (Figma), Google Play Console, Steamworks, Game Development, Network Programming.

10 000 USD AppMaster.io — Development of the platform core (Server-Driven UI SDK,
App Development for Android
For 4.5 years, I was solely responsible for the design, development, and scaling of the modular architecture of the core platform AppMaster.io — a visual development environment for mobile applications. I ensured full-cycle delivery of features in close collaboration with a cross-functional team (Backend, Frontend, QA). Key achievements: Designed and developed from scratch a native Server-Driven UI SDK in Kotlin + Jetpack Compose / UI + Coroutines + MVVM. The SDK became the foundation of the entire platform. Developed a complex business logic interpreter (over 500 blocks) for visual programming directly on mobile devices. Created an internal library of 50+ dynamic custom UI components in native Kotlin — significantly speeding up interface generation. Successfully integrated complex low-level and external SDKs into the platform core: WireGuard VPN, Regula (document verification), Google Maps / Sign-In, Mapbox, Biometrics, In-App Purchases. I deeply engaged with both architecture and performance as well as product features, ensuring high quality and scalability of the platform. Key skills and categories (for the form): Kotlin (Advanced), Jetpack Compose, Android SDK, Coroutines, Flow, MVVM, MVI, Clean Architecture, Modularization, Dagger/Hilt, Server-Driven UI, SDK Integration (VPN, Maps, Biometrics, IAP), Platform Architecture, Scaling, Refactoring.

5000 USD Ring App — High-performance spam call filtering system
App Development for Android
I participated in the development and growth of PingOcean's key product — Ring App (an application for identifying and blocking spam calls and combating fraud). The app has been launched in the international market. My key tasks and achievements include: Developed a high-performance incoming call filtering system based on dynamically updated spam number lists. Implemented algorithms for detecting test calls, helping to identify fraudulent schemes on the side of telecom operators. Designed local data processing without collecting personal user information — strict compliance with Google Play privacy standards. Developed a reward system (gamification) for completing user tasks, which significantly increased app retention. Responsible for full-cycle publishing of updates, A/B testing, and technical support in Google Play Console. The project provided me with excellent experience working with high-load real-time systems, security, privacy, and retention mechanics. Key skills and categories (for the form): Kotlin, Android SDK, Jetpack Compose / XML, Coroutines, Security Architecture, Call Filtering, Working with Telephony API, Privacy and Compliance (GDPR/Google Play), Gamification and Retention, A/B Testing, Google Play Console, Full Release Cycle.
