    Top Rated | Lead Game Developer | Clark University Graduate | 8 Years of Coding ✅ , EDUCATION I graduated with a Bachelor of Arts degree in Computer Science and Math from Clark University in Worcester, Massachusetts. My time in this school was enriching both personally and academically. Clark's CS department was small but had extremely passionate and dedicated professors that made sure to expose me to all the intricate fields a programmer needs to be aware of to thrive in today's tech world. Significant courses: Assembly Language, Theory Of Computation, Design and Analysis of Algorithms, Automata Theory, Machine Learning, Computer Vision, Software Engineering, Discrete Math, Numerical Analysis, Calculus, Linear Algebra ✅ , GAME DEVELOPMENT My passion for game development started in the summer of 2015 when I used the Libgdx Framework to learn the inner and low-level workings of physics engines, rendering systems and game loops. I recreated the gameplay of one of my favorite titles; Super Metroid of the SNES. Coding each detail to simulate the experience of a 20 year old game was breathtaking. In 2017 I designed, developed and published Infinite Flydown to establish myself as someone capable of creating games from start to finish. In my senior year of school I designed my own honors course where I created an engine for the development of 2D Platformers. This engine had many systems including map editors, physics based mechanics, pooled object systems, enemy AIs, and more all coded from scratch. This served as the foundation to many of the games I have developed since then. In 2019, I created Bumper Aliens, a fully fledged hyper casual 2D shooter with innovative gameplay, unlockable/upgradeable ships, unlockable drones, missions system, in-app purchases, unique ad experiences, analytics tracking system, and more. ✅ , MOBILE APP INDUSTRY I have spent the last 5 years learning the ins and outs of what makes casual mobile games addicting and appealing. Did you know over 60% of players don't open a game again because they aren't given any tasks to complete? That push notifications will increase retention rates massively? I have published over 8 games in app stores and developed more than a dozen; I know how to deal with the intricacies of the whole process from start to finish. I work with the Cross-Platform frameworks such as Libgdx and Unity to deliver tightly packed games with what they need to succeed. 🕹️ Lead developer in - Space Battle Box Arena (Steam, Android, IOS) - Spell Blast (Android) 🕹️ Lead developer and artist in - Word Wall (IOS) - Foka Go (Android, IOS) - Bumper Aliens (Android, IOS) - Worm Hole Madness (Android) Check Portfolio for full list of game development projects I have worked on!

    I have over 3 years of experience as a Solidity and React.JS developer, 4 years of experience as a Software Engineer, over 10 years of experience in general programming and have Master's degree in Computer Science. I can create multiple custom DEFI solutions and also fork existing ones. Blockchain development is a very complicated and sensitive business and you should choose to work with professionals that develop safe and tested smart contracts. Having an untested and poorly written smart contract can put your users funds in danger and ruin your entire project. Some of the many projects which I've built in the past are: • NFT launches/drops : regular, whitelisted, gasless whitelisting using wallet signatures, Merkle Tree etc. • NFT staking, merging etc. • ERC20 token ICOs: regular, whitelisted, gasless whitelisting • ERC20 tokens with custom specifications: burnable, tax fee on buying/selling etc. • DeFi forks of platforms (Uniswap, Pancakeswap and others) • Creating a bridge for wrapping NFTs and ERC20 tokens between chains • Custom smart contract solutions I am highly capable of building you full custom solutions on Ethereum, Binance Smart Chain, Polygon and many other chains. Other languages I have been coding over the years are: C++, C, Python, Javascript, DevPascal, Java, Kotlin, Rust, Matlab.
