Greetings, I am an experienced developer from the United States that has over 20 years of experience in a variety of environments including all the one's listed here. I am an eager student in technology. I have been into the crypto space since 2017 and I am very passionate about it's future. I believe I could be a great asset to your company. Let's chat.
Been a Fullstack Web Developer for 22 years , started with ASP,PHP, moved on to C#, ASP.Net, Php frameworks then Discovered Node Js in 2015 and Angular, React etc , Started with Crypto 2 years ago and Trading actively then started learning Solidity programming and Web3, ethers ,Truffle ,Remix etc earlier this year .Very passionate about Defi and Gamefi and NFTS and love play to earn games and staking and Defi .Looking for a job where I can utilize my existing skills FullStack Web and learn and get more experience in Solidity ,web3 etc .Looking to grow and be part of an organization that will help me grow with them .
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.

I’ve just came across JST Capital profile. I’m a software engineer with 7 years of experience. My background is in fullstack engineering though a bit more focused on the backend. and I’ve worked with different languages and technologies. For the last 4 years I have worked mainly with MERN stacks. I have recently started learning Go and I’m currently contributing on 2 projects open-source in that language so I'd say I'm getting familiar with it and I have also worked in the blockchain space for 4 years.
I think I could be a good fit. I’m sending you attached my resume and these are my LinkedIn (linkedin.com/in/federicoalconada) and Github (github.com/fedealconada) profiles.

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.
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.
