Of course, programming is always a learning experience and I am to this day doing that. Now, I have been freelancing for the past 5 years. When it comes to my core fundamentals Blockchain, Mining, developing wallets, exchanges both DEX and CEX, NFT marketplace places and Smart Contract are on the top. Also, I have worked with AWS for 3 years which arms me with excessive dev-ops and server-side security experience. Along with that, I have developed and launched 140+ mobile and web-applications with active userbase to this day. Beyond this, I lead a team of seasoned blockchain developers of around 40+, who excel in developing all things related to blockchain and Metaverse. Tech Stack that I have worked with: * Node.Js, Php, Laravel, React, React.js, Electron.Js * Solidity, Rust. * ERC20, ERC721, Defi Apps, DEX * Python, Django, Django REST framework, Flask * PostgreSQL, MySQL, Redis, MongoDB * Docker, Docker Compose, CI/CD configuration * Automation and Scraping: Scrapy, Selenium, requests, BeautifulSoup, etc * Core web: XML, JSON, HTML, CSS, JavaScript. * WordPress, Shopify, WIX * Google Cloud, AWS, Azure * Git, GitLab, Bitbucket, Heroku Chains that I have fully Grasped: Bitcoin | Ethereum | Solana | XRPL | Stellar | Hyperledger and | Corda {and safe to say I can work on almost all the chains} With AI/ML, I have worked with several algorithms Decision Tree, KNN, Random Forest Algorithm, and Linear Regression. On top of that, I have been following OpenAI closely and looking to actively start working on my own AI projects. While I won't say I am the best or I can do everything, what I can assure you is that I can be the WIZARD that can resolve all of your issues after doing RND and I am up for hour-long discussions to make sure I understand your requirements perfectly. I have all hands on deck at this point! So let's discuss this further. menos

To observe, to jot down, to form, to be astounded at nothing, to treasure the eccentricities, to let nothing go down the drain, to make something, to make a great flower out of life, even if it’s a cactus. Words have enchanted, educated, and inspired me since I was a child, which is why I love working with clients to help their words have the greatest possible impact on their audience. I am an expert at connecting brands with consumers. If you really want to hire a fantastic candidate, expand brand awareness, and breathe life into your project, then I’m your guy!! My experience as an educator allowed me to hone my problem-solving skills for myriad young people and adults. I have worked with well-known international companies helping them to achieve their creative goals: ✅ Texts for advertising purposes (handbooks, case studies, blogs, landing pages, social media, ads, and web content), ✅ to literary creations (plots for movies, short stories, scripts, poems, novels) that make readers’ imaginations take flight. My Creativity and Graphic Skills will undoubtedly offer you a clear, impactful, and entertaining copy. Other areas of expertise include: ✔ Business Proposals and Plans ✔ Thesis and Research Writing ✔ IBM SPSS Data Analysis ✔ Academic Writing Tasks ✔ Proofreading and Editing I'm known for my ability to edit texts quickly while catching the mistakes and areas of weakness that others overlook. I am a passionate perfectionist when it comes to a succinct, well-written, and error-free document. TRY ME and you won’t be saddened.
