  Worked on multiple commercial game projects, primarily Sector 13 and Planet Pokémon. Beyond development, this period marked a major stage in my professional growth, as I was mentored by senior game engineers from the United States. Through close collaboration, I gained a strong foundation in game architecture, design patterns, clean code principles, gameplay programming, and engineering practices for large-scale game development. The knowledge and experience acquired during this time have continued to influence my approach to software design and technical leadership throughout my career.

  Sector 13 is 3rd-person starfighter combat. Personalized weapon load outs and a huge variety of starfighters give you the ability to optimize your war machine to your preferred play style. Intuitive controls make it easy to navigate around and through the natural and man-made obstacles in Sector 13's stellar arenas

  Contributed to the development of the global version of Sky Garden, an award-winning mobile farming MMO. The game was built on a proprietary C++ game engine, providing hands-on experience with low-level engine architecture, rendering, resource management, and cross-platform game development. Working closely with the engine allowed me to develop a deep understanding of how game engines are designed and optimized.

  I was also responsible for bringing the game to the iOS platform, adapting engine and platform-specific systems to ensure stable performance and compatibility. I successfully completed the iOS port before leaving the company to pursue new opportunities.

  SKY GARDEN is an addicting casual farming MMO game, the best farm game for mobile phones and tablets. Sky Garden wins the honor award People’s Choice Award at the 13th IMGA GLOBAL (2017) with a record of 7,000 votes from all over the world.

• Unity developer at Vulcan Labs

  01/2018 08/2018

  Developed multiple casual, AR, and VR applications for iOS and Android with delivery cycles ranging from 2–3 weeks. Responsible for gameplay programming, platform integration, optimization, bug fixing, and publishing support.

  Dot Art: Color By Number is a game that you color the whole picture by tapping one pixel to another until you are done. At first I thought this game is for children get to know about colors, but then I got to make it, had more time to play it, I got addicted myself, I played it whenever I was in line for a movie, or had sometime to kill.

  AR Soccer Strike : ARKit Games is an AR soccer game, the game is pretty simple, flick your finger to kick the ball, try not to kick the ball the goalkeeper ,the guards or outside, the higher score you get the harder the game so be careful

  Jurassic Park ARK (VR apps) is a VR ... well I don't think I can call it a game, it's pretty much nothing to play but walking around in some islands and watch dinosaurs. Well, that's it, I made this ... not a game in 2 weeks so well, don't expect too much, just you know, good VR experience though.

  VR Horror: The Halloween Room (VR apps) is a VR horror game, walking alone in an abandon hospital, only one way out, make the wrong choice and you are dead.

  Xmas Room(VR apps) is another VR horror game, the icon is a happy Santa face, don't be fool by it, that Santa is crazy and deathly. Your mission is kind of weird too, you sneak into his house and try to steal all of his presents before chritmas. If he found you, you was as good as dead, so try to be careful

  Merge Ball is a mini game that I cloned from another app names Fuzed Ballz, the rule of the game is pretty simple, 2 or more balls with same color merge into a bigger ball, when the ball is big enough, it will explode and give you more balls to play, you lose when you are out of ball.

• Native developer at SEGA team

  Contributed to several well-known SEGA mobile titles, including Virtua Tennis Challenge, Sonic the Hedgehog 4: Episode I & II, Crazy Taxi Tycoon, and Memory Lane. Worked across both Unity and proprietary native C++ projects, adapting quickly to different codebases, development pipelines, and platform requirements.

  My responsibilities included implementing new gameplay features, fixing production issues, optimizing performance, and maintaining existing game systems. In addition to C++ development, I worked with Java (Android) and Objective-C (iOS) to implement native platform functionality, integrate mobile-specific features, and resolve platform-dependent issues.

  This role significantly broadened my cross-platform expertise, strengthening my understanding of native mobile development, engine-level programming, and the interaction between game engines and operating system APIs.

  Continued collaborating with a long-term client who returned after previous successful projects, demonstrating confidence in my technical expertise and ability to deliver high-quality results. I worked on Land of Wonders, a mobile kart racing game, where I inherited a large legacy codebase developed by another team. By quickly understanding the existing architecture and development patterns, I was able to integrate new features, resolve technical issues, and deliver the project on schedule with minimal onboarding time.

  Land of Wonders is a beautiful cartoon style racing game, you will find tons of different motivation while pick up your favorite food characters with the fun, fast and furious cars in this adventure toward your goal of balance to build a collection of powerful driving skills, also upgrades to use and outsmart your kart racer opponents.

  Conceived, designed, and developed Minesweeper 3D World as a personal project in approximately one month. The project reimagined the classic Minesweeper gameplay in a fully 3D environment, allowing me to explore new gameplay mechanics, level design, and user experience. Built independently from concept to completion, including game design, programming, UI, and polishing. Although it was created primarily as a passion project and was not commercially marketed, it reflects my ability to rapidly prototype and deliver complete game experiences.

  Minesweeper 3D world is a single-player puzzle mobile game. The objective of the game is to clear lands containing hidden bomb without detonating any of them, with help from clues about the number of neighboring mines in each field.

• Unity Lead at Radx

  01/04/2020 30/12/2021

  Joined the company as a full-time remote engineer after successfully delivering a freelance project. I was initially brought in to solve a technical challenge that had blocked development for several weeks, completing the solution within 24 hours. This established a long-term collaboration where I became the go-to engineer for complex technical challenges and new project initiatives.

  As the Unity Lead, I provided technical leadership while mentoring two junior Unity developers through code reviews, architecture discussions, debugging sessions, and day-to-day guidance. I helped improve development practices, assisted with technical problem-solving, and supported their professional growth while ensuring project quality and timely delivery.

  During my time at Radx, I contributed to numerous WebGL, AR, and VR applications for international clients. My responsibilities included developing interactive WebGL experiences, implementing AR solutions, integrating Photon multiplayer networking, and building virtual online exhibition platforms where companies could showcase products, host live events, and provide interactive mini-games for attendees.

  Although many of these projects were built for temporary marketing campaigns and online events that are no longer publicly accessible, they provided extensive experience in rapid development, cross-platform optimization, multiplayer networking, and delivering production-ready solutions under tight deadlines.
