As a UT CS alumnus who is passionate about learning different technologies and getting self-started, I've worked on a lot of cool projects in various industries with professional team members. Started learning programming with C/C++ and took part in a large-scale web project as a back-end Java developer during university. While working on many productive projects, Javascript became the biggest point and I also had valuable experience in other programming languages, frameworks and related technologies. Currently, Web3 has sucked me in and I really enjoy building dApps and Smart Contracts on top of EVM-based and Solana networks. Providing good solutions and building infrastructures of projects including database design are my other proud skills. And I never shy away from asking or learning new technologies. Looking forward to exciting opportunities, working in a fast paced environment, and fostering a strong relationship with all of my clients.Solidity

I bring a diverse set of skills to manage nearly any IT problem. I don't claim to know everything, but I've always been tenacious and I won't stop until I figure it out. Hiring a developer can be a gamble sometimes if you're not careful - low-cost developers entice potential clients with low budgets and promising they can do anything. What they're after is just the job, not necessarily making your project succeed. If a freelancer charges a low rate and seems to have plenty of time available, there's probably a reason. A good freelancer will be upfront if something is outside of their skillset or if they can't fit the project in their schedule, and is careful not to overpromise. Wasting a client's time and money to deliver low-quality results isn't a sustainable business. If your project uses some technology I'm unfamiliar with, I generally don't charge for the time spent educating myself on it. I like learning new things, and it may be useful to know in the future. Whether you need a brand new application, bugfixing/refactoring a legacy codebase, website/CMS management, Linux/Windows server administration, or anything else involving software, check out my profile details and my portfolio of work to see if I might be a good addition to your project! [NOTICES] - I am happy to sign an NDA for your project if required! - I'm a native English speaker, if you consider what the southern states speak to be English 😅Solidity

Blockchain developer and defi enthusiast with over 2 years of experience in the field. With all the recent hacks happening, developing a decentralized app is a very risky proposition. You don't want an application handling millions of dollars, getting hacked due to a developer bug. This is where you need me. With a development history of over 10 products which include both DeFi dapps and NFTs, I have the required experience for this job. I would love to gain more experience in this field, by working on new and innovative projects.Solidity
