Active a year agoAvailable now📍Santa Ana CaliforniaEC2JavaScript AWS TypeScript Angular React Frontend Fullstack Express REST MongoDB NodeJS Lambda S3 RXJS HTML5 CSS3 Bootstrap AWS Unit Testing SQLHello, I started out as a MEAN stack web developer but now I use any skill that gets the job done. Lately I’ve been running Python scripts under crontab automated tasks but still use NodeJs/Express for web servers which are running on AWS EC2s or AWS Serverless Lambda functions. On the frontend I use Angular with TypeScript but picked up React to strengthen my frontend concentration. I’m good at building out css wireframe components that are responsive with Bootstrap and flexbox. I either host the frontend distribution folder in Amazon S3 buckets or on Github Pages. In the middleware world I enjoy playing around with APIs to grab data on the fly and display it to the user. I use Postman to test APIs and prefer the observable pattern via RXJS to handle REST calls on the frontend. On the data layer I’ve used MongoDB, DynamoDB, RDS, and Postgres. I write Nodejs/Express CRUD calls to those databases either in EC2s or Lambda functions. In terms of full stack my biggest weakness is probably CI/CD. I understand it, but would like to get better at integrating it in my own workflow using Gitlab. I’m interested in Bitcoin in particular after finding the Bitcoin Twitter community and the On-Chain Analytics community. I’ve worked at a Bitcoin Startup called Kapitalex.com where I mostly helped design and build the VueJs frontend. My portfolio is at: https://serge.link Sincerely, Serge UrakhchinPython Developer
Active 2 years agoAvailable now📍New YorkDear System 9, I am a fairly recent graduate of Lehigh University with a Bachelor of Science in Computer Science and a minor in Data Science. Currently, I work as a Software Engineer at CGI Inc. As an engineer, I am fascinated by working with data, and my interests lie in using the power of data to create innovative software that can be used by people across the world. Because of this, I would love the opportunity to be part of the engineering team at System 9. Last summer, I did a remote internship at Blockchain Center NYC. I was part of a team that developed an ERC-20 Oracle smart contract to publish aggregate semantic data pertaining to cryptocurrencies. My role on the team was to open up a persistent websocket with bitmex.com using a publisher/subscriber pattern to receive real-time messages from their public chatroom. I then wrote the messages to a Redis TimeSeries database where they are aggregated with chat messages from several other cryptocurrency forums. Next, the chat messages were sent to the Google Cloud Natural Language API to determine the overall sentiment for different cryptocurrencies. Finally, using web3.js, the output of the natural language API is sent to the ERC-20 oracle, developed as a team with Solidity, to be published on the Ethereum blockchain. I used Docker Compose in order to containerize my code and ensure that it would be compatible with code written by others on my team, some of whom used different languages. Early last year I set up a stake pool for the cryptocurrency Cardano. I maintain two nodes, a block producer and a relay. Both of which run on AWS EC2 instances. The nodes are largely self-sufficient as I configured the EC2 monitoring dashboard to reboot the instance when traffic on the network interface drops (the node crashes). Then, I created a service file using systemctl that will restart the node software itself on system boot. I also implemented several security measures such as a restrictive firewall that only allows the block producer to accept packets from my relay node as well as storing cold keys and private keys offline, not on the instances. I look forward to hearing about how I can contribute to the engineering team at System 9! Thanks, Chris- Hello Thanks for reviewing my proposal. I’d like to work with you. As a senior web developer, i've lots of experiences in web development especially JavaScript Stacks, MERN, MEVN, MEAN. In details, about node.js, Express&Sequelize with MySQL, Koa&Knex with PostgreSQL, Express&Mongoose with Mongodb, Passpoart and GraphQL. About the front-end, senior experience in react.js(reducers, redux, redux-saga), Vue.js(vuetify) and Angular2+. And about the team-work, strong experience in Github/GitLab/Bitbucket, Trello/Jira and Slack/RocketChat. Especially blockchain/cryptocurrency In the blockchain, I've experienced in building MouseBelt blockchain explorer in BTC, ETC, and LTC. At that time, I've built the private key generator using mnemonic, sign, send transaction, as well as get transaction list for all type of operation. Also, I've experience with installing stellar(Stellar Core&Horizon Server)and have been part of team developing Smart contract, Coin Node API, Mobile node sdk, ICO/exchange development. Achievements: - Successfully build the blockchain nodes for ethereum, bitcoin, stellar, neo,etc. - Build REST APIs to access nodes functions. Responsibilities: - blockchain and cryptocurrency design and development. - token, smart contract development and audit - Backend development. - technology research To prove my skills, i'm ready to have a technical interview and test project.

Full-Stack Developer
Active a year ago - Dear Prospective Employer, I am a Full Stack Engineer based in Islington, London. My psychology BSc involved a lot of experiments and statistics. For my dissertation, I did computational modeling work on human memory, and this was when I first started learning Java. My MSc in computer science was a conversion course that focused heavily on Java and C, contrasting he two languages to teach us the fundamentals of software engineering. I started web development in 2014 working on a psychology website with PHP, gaining experience through building personality tests and HTML5 games. My past software development experience involves various freelance gigs with Java and Spring. I switched to MERN stack in 2018, which I use for most of my projects. My recent industry experience has been vital to my development as as software engineer. The tech I worked with include React, Next.js, Gatsby, NestJS, MongoDB, Redis, and RxJS. These roles were crucial to my development as I collaborated with a large team in a large Codebase, across multiple repositories. I was able to put theory into practice with DevOps as I began working with CI/CD pipelines and with development, staging, and production environments. I also gained AWS experience, deploying with AWS ECS/EC2, and working with other services such as SES, SQS, S3, and configuring the deployment with GitHub Actions. My expertise is in the domain of finance, specifically Cryptocurrency and BetFair Trading. I have advanced trading knowledge, including Technical Analysis, Order Flow, and the Psychology of Trading. This experience comes from my employment in CoinRule where I integrated numerous Crypto Exchange API's, and from my personal experience with leverage trading Binance Futures. I also have a lot interest in Blockchain technologies such as Solana. I can add a lot of value in these areas. Flash Betting Architected and developed Sports Trading Software for trading on the BetFair Exchange. Built using MERN Stack and made into Windows and Mac software with Electron. Front End development with React; state management with Redux Thunk & Saga; Back End development with Node.js; integration of the BetFair API. This is high-frequency trading software required optimisation to fix render lag issues. Other work includes community buidling with Discord for bet traders to come together. Work also included development of the website with React & TailWind, the API for authenticating users, and a discord bot. Because it is a small app, Heroku is used for deployment. Crypto Trading Software An in-progress project: I am currently integrated various exchanges, caching the data, and performing statistics to create trading signals based on various indicators such as Harmonics, Value Area, Open Interest, Elliot Wave and more. The tech I am sing include NestJS, Redis, RxJS, React, and MongoDB. I will deploy my severs on AWS ECS/EC2.
