About

I started working as a professional developer at the age of 19 but my first app was a QBasic app for DOS developed for my dad when I was 12... it's been a long time since I started to develop!!

Backend, web, desktop, game and mobile developer using mostly Microsoft technologies (Azure, asp.net, asp.net core, Xamarin, javascript, typescript, several UI fwks, Blazor, etc).

Experienced DB developer, indexes, tuning, queries and modeler, using sql and no sql databases, mostly Microsoft databases, SQL Server, Azure SQL, Cosmos DB, etc.

I'm a DevOps fanatic (CI / CD using AzureDevOps, yaml, docker containers and Microsoft app center for mobile apps) and Agile lover with Scrum certification.

Learning Python + AI as a hobbie. Blockchain enthusiastic, some ETH smart contracts POCs.

As you can see in my GitHub repo (https://github.com/vackup) or in my personal blog (www.hernanzaldivar.com), I'm technologist! I love to play with new and different technologies and I learn them very fast! So if there is something needed that I don't know, I'll learn it in a breeze.

I've worked for several companies and several roles that include CTO, team leader, innovation lab leader, developer and architect and for several industries (payment, health, bank, social networks, gaming, insurance, agro, etc).

Currently I'm working for a healthcare company based in Portland where all the micro UIs are developed using React and Node and the backend in .NET Core. I've been working on this project since November 2019.

I've been part of a team working for a company that provides accounts payable (“AP”) automation software and payment solutions for middle-market businesses and their suppliers based in Charlotte, North Caroline for a couple of years where we had to travel to Charlotte one month per year to be with the team locally.

I used to have 2 iOS apps published and lots of POCs including Android. Creator of hypstr, an iOS app that let’s you customize your digital life to the fullest,letting you download great designer wallpapers and a game called "A comic of zombies". Worked on a native mobile xamarin fishing social network app for iOs / Android remotely for an USA client.

That's me, a guy from Argentina who tries to make things more efficient in a different way and having fun in the attempt. I love to travel and learn about new cultures, do snowboarding, spend time with my family, kids and friends. I take care of enviroment and try to make the difference.

Team leader of an 8 members team. Working for a Portland health tech company that helps employees to improve their health. It provides personalized recommendations and information that is relevant to each individual, at every stage of life. The app used to be a monolithic app that was hard to deploy and evolve. We started the migration of the app to a microservice architecture written in .net core / 6 using a sql server db for each one and rabbitMQ. The frontend was also moved to a microUIs architecture that can be evolved and deployed independently. They are developed using React and NodeJS. Agile / Scrum. Responsibilities: ● Work closely with your Product team, Design team, and QA to create an amazing and intuitive experience that solves problems for our users. ● Participate in the entire development lifecycle: Grooming, development, automated testing, documenting, and refactoring to aid the product team in releasing high-quality code quickly. ● Participate in code reviews for your product team, and other teams when required, and use them to improve the quality of the code
