Active 1 years ago๐ArgentinaHey there! The first thing I'd like you to know about me is that I'm fascinated with the crypto/blockchain ecosystem, and I am determined to make a career in this field. Not so long ago I joined Axie Infinity, mostly for learning purposes, and then I got so hooked that started building a side project to manage my Axie teams. From that point on, I started learning like mad. Right now, I'm doing a MIT course about blockchain, and also reading/watching the Ethereum resources. My next step would be to learn web3 in deep, so I can combine it with my frontend skills. Now that you know that at least you could expect from me to be a highly motivated person, I'll tell you why I think I can be a great fit for this job: - I have 5+ years of experience working as a full-stack developer. - I've been working with Javascript, Typescript and React since the start of my career. So this is the area in which I am more proficient. You can see my recent React Skill IQ in my Stackoverflow's profile: https://stackoverflow.com/users/story/8924381 - Even if the frontend constitutes one of my strengths, I don't have less experience building backend features. Through the years I've used many backend languages, such us PHP, Python, Java, Scala, and Ruby. I'm not afraid of learning new languages, I believe they are just tools to an end. - I'm a GraphQL fan, and I've been working with it even before I started my career (I used it at university, for creating the API for my final project, along with React too). And since that point on, I used it to built APIs with complex schemas (ecommerce platform, with lots of business rules). - I like software in general, and I like reading, so I try to always keep learning about software architecture in general. I couple of books I can recall: Building Microservices, The Pragmatic Programmer, Software Estimation Without Guessing, Shape Up, Domain Driven Design. I believe in life-long learning, so you can also expect from me to be a super curious person. - I have experience working with TDD. The current company I work for take testing and quality very seriously. - I'm conformable with taking ownership and leading. I've been doing it for both my current company. I was also the lead of a 6 people team, for a freelance project (ecommerce platform for a local retailer.) - And lastly but not less important, I strongly believe that team collaboration, and constant and precise communication is key to success. I like to build bonds with the people I work. Nothing more beautiful than sharing achievements with your people. I hope you see me as a good candidate, and if so, I'm eager to have a call, to do any test project, or whatever you see feet. Thanks in advance!Senior Blockchain Developer

Active 4 months ago๐KosovoHello, My name is Dhurim Kelmendi. I am a Full-Stack Engineer by trade and I believe that I fit the requirements 100%. I have nearly an identical set of key responsibilities at my current position. I regularly convert functional and non-functional requirements into flawlessly working applications. In addition to this I lead teams and ensure that all the aspects of an application, including but not limited to: UX, scalability, code quality, security are given the necessary attention. In my free time, I like to blog and share my knowledge and experience in my Medium profile: https://medium.com/@dhkelmendi I currently work as a Backend Engineer at a startup that is developing an app that helps children create visual stories. The product is built following TDD, and using technologies like Golang, Postgres and AWS for a reliable, secure and fast platform and React/React Native for the frontend, giving users a very high-performance solution. Upon request I can provide screenshots and diagrams of the architecture, but the code has also been committed to private work repositories. My current position is a perfect example of what youโre looking for. I was brought on to aid the development of the application at a startup with a very flat hierarchy, meaning that I had to wear different hats, I had to make technical decisions, provide support to my team members and also learn aspects of software architecture so that our application is as reliable as it gets. I also learned more about Kubernetes and Docker, which we utilized for deployment and cluster management. P.S. As a display of my Golang skillset, I have developed a simple vending machine, this is the link to the GitHub repository: https://github.com/dhurimkelmendi/vending_machine I look forward to hearing back. Thank you, Dhurim Kelmendi- I have a serious technical background: 10 years in this industry as a Software Developer, 3 years as a CTO including all software management responsibilities, 2 years in blockchain field in CTO & Developer positions plus 5 years of IT Engineering education. I think it would be very useful for you to have this type of team member in your project. I am very inspired by what you do and I would like to be a part of it. It is always interesting to me to create new tools, tech projects and I think we are ideally suit to each other :)

Senior Full Stack Web & Blockchain Developer
Active a year ago Full Stack team lead
Active a year ago๐รsterreichIm a senior IT manager with 10+ years plus in the software industry. I have an agile mindset and know how to achieve results, but also how to work with the engineers, as I will always stay an engineer myself. Im able to oversee, plan and execute all development stages, I know up front what can go wrong. I managed turnaround, migration and green field projects, mobile apps, large infrastructure backends, and high-throughput applications, incl. payments,interfaces to banks, PCI compliance and so on. Im run a deep dive approach, that means I understand all the workflows, processes, design them, decide what we build and why we build it. Most engineers are only effective as a workforce, when guided, most of them want to "run berzerk" and run alone, but only a team can be effective and deliver high quality. I will streamline the development, oversee the tasks, prioritize accordingly as I simply know how things must be done. I manage risk, I disuss with the team and find a consensus. Ive seen a lot, managed a lot and built a lot, so Im not that usual frontend or backend developer anymore, more like a generalist, it does not matter what tech stack you are using. I managed all from c++, to java JEE, several gui frameworks, databases, microservices, AWS cloud/, TDD, angular, react native, whatever bring it on. Solidity , yes I worked as a project/product manager in a crypto startup on our own blockchain, handling everything from design to flows, smart contracts, app, bridge, interfaces and I audited several contracts for ICO projects around 2017/2018. I connected several android apps to liquidity providers, and worked with bot developemnts, and source portations of ethhash to fpga. Im missing some focus on GraphQL (while this is really cool), and python. But no problem for me to ramp this knowledge up a bit. If you need experience and someone who has a feeling for frontends , frameworks, interfaces, lazy loading, design, and learned the difference between UX and UI by hard, Im the man for that job.- Hi. I am a senior Fullstack Web & Blockchain developer, specialized in custom cryptocurrency and blockchain development, having extensive experience in ICO, POS โ Proof of Stake, blockchain website, web portal, & smart contracts application development.
