Freelance Web3 Developer - Ray Deck

Hi! I've been leading and teaching technologists and tech-enabled businesses for over 20 years in various startups I have grown. I learned coding as a child, studied (what we now call) data science in school, and have worked in finance, consulting, and building a series of software startups with various technologies: Tensorflow, Swift, Objective C, React, React Native, Typescript, Node.js, Visual Basic, Solidity... the list goes on. I'm super practical about technology and how we can cut our cost and time through good tooling. If I can help you find a shorter, easier path, I will. That's why I investigate the integration of quality nocode services into a stack - where is there an opportunity to radically cut costs and improve velocity? My love is teaching people to be better technologists. Help them see the problem and resolve the issue, rather than just lay my hands on the keyboard. I'm hoping to do this as a Codementor as well! I bring this teaching approach to community participation and events as well as my companies and 1-1 teaching. I've spoken at a number of conferences and meetups on React Native, Swift, AR, and machine learning. Currently, I run a Group Mentoring meetup for people interested in no-code. You can sign up at https://statechange.ai/meetups. And I help where I can with humans coming up. We're all busy people, so on-demand help can be hard. The best way to get a session in the near term is to book a time with me via my calendly: https://calendly.com/raydeck/codementor A couple of things about how I work: I provide 1-1 mentoring on here, as opposed to longer-term work. I also do not provide free sessions anymore. However, if you are dissatisfied with how a session is going, tell me so and you not be billed. I measure myself on people helped, and the challenge of the problem that they can overcome - with just a little help.

Freelance Web3 Developer - Majid Kareem
Freelance Web3 Developer5.0 (193 reviews)

I'm a Full Stack Developer with over six years (6+) of experience, and I've spent the last two (2+) years diving deep into Solidity and web3.0 development. Along the way, I've developed a strong passion for blockchain and emerging technologies. Recently, I added a new dimension to my skill set by earning a Project Management Certification from PMI and gaining some hands-on experience managing projects. Now, I'm blending my technical chops with strategic project oversight, which has been incredibly rewarding. I'm always curious and eager to learn, especially when it comes to tech that’s shaping our future. Blockchain and AI, in particular, have caught my eye because of their potential to revolutionize the open internet and how we build software. If you’re curious about what I’m working on, feel free to check out my [profile on Codementor](https://www.codementor.io/@majidk) Whether you want to chat about a project, collaborate, or just exchange ideas, don’t hesitate to reach out.

https://satwikkansal.xyz I have been freelancing since 2k17. I love the process of turning ideas into code, and you can count on me for writing good quality code. Aside from freelancing, I've authored a popular developer project called "What the f*ck Python?", and I've developed multiple courses & tutorials for many companies including IBM, Packt, Educative and others. Presently, I'm working on a book on Python for O'Reilly. My areas of expertise include Backend System, Automated Trading Systems, and Decentralized Applications (a.k.a Dapps on the blockchain). I've worked with a few startups in the past (including a couple of my own), helping me learn how to build products in a fast yet cost-effective way. I try to actively engage with Open Source organizations and occasionally write looong tutorials on specific technical topics. Luckily, some of my works were trending on HackerNews, Github, Newsletters, and Podcasts like PythonBytes, PythonWeekly, DataElixir, and more. If there's an interesting opportunity to discuss, please drop me a message, I usually get back to messages in a day. Always excited to work on cool projects :)
