Juan O.

Vetted Jest developer in Colombia (UTC-5)

I am Juan Ortiz, a Frontend developer based in Bogota, with a focus on React Development. I have 5 years of experience working with organizations across the globe. I have a focus on code quality, maintainability, and enjoy working on diverse teams. I have a strong work ethic, and am looking for full time opportunities. I recognize the importance of unit testing and strive for code coverage above 80%. With unit testing, I'm able to test advanced components leveraging powerful mock tools. I take great pride in writing unit tests not only for my code, but for my peers. I am eager to take on new challenges outside of my comfort zone. More recently I implemented a live streaming service using the RSTP protocol leveraging gstreamer. The challenge with this was that I have to convert a h.264 encoded video into a webM file, and then send it into a Nodejs TCP server, which was later used to stream video over the web.

Full-Stack Developer and Open Source Contributor with over 12 years of expertise in web (Angular, React, VueJS), mobile (React Native, NativeScript, Capacitor/Ionic), game (Phaser/PixiJS/Unity), blockchain (Solana, Ethereum/Chainlink) and cloud (GCP, Azure) development. Skilled in building scalable architectures, seamless user experiences and driving innovation through Open Source. Proven ability to deliver impactful solutions across industries such as Digital Media, Aviation, Fintech, Healthcare, Delivery, Energy, Retail, E-commerce, Luxury Goods, Blockchain and Information technology. During my career, I’ve had the privilege of leading impactful projects and contributing to groundbreaking technologies. At BAXUS, I was the **first Founding Full-Stack Engineer**, working directly with the CTO and Head of Business to establish the foundational architecture for the web and mobile platforms. I created and maintained a **monorepo for the frontend (Nx)**, enabling Server-Side Rendering (SSR) with React and RemixJS, and integrated Solana blockchain technologies to provide secure and transparent transactions. On the backend, I developed a **modular monorepo** using NestJS, orchestrated microservices communication with Temporal, and leveraged Docker to streamline development and deployment processes. As part of BAXUS’ growth, I played a key role in the acquisition of a mobile application. I successfully migrated all its Python-based services to Node.js, centralizing data within the marketplace architecture. This migration not only streamlined information management but also enabled seamless integration of new marketplace functionalities into the mobile app, enhancing the user experience across platforms. My contributions helped BAXUS reach over **140k users**, and I was also responsible for designing and executing Python scripts to successfully migrate millions of records between databases, ensuring scalability and consistency. Creator of @proyecto26; an Open Source organization changing the world with small contributions 🧚‍♀️ Through my Open Source contributions, I’ve reached millions of downloads from npm, and my passion for sharing knowledge has led me to speak at international events like CityJS, JSConf and Microsoft DevDays, as well as mentor local communities such as CodeYourFuture, ColombiaDev/MedellinJS, LaPlazaDevs, etc. To be, or not to be, that’s not the dilemma… Let it be 🌱 - J.D.
