Juan L.

Vetted Test unit developer in Spain

Senior Software engineer, DevOps, and pentester passionate with 7 years of experience. My programming languages are Java, Python, Typescript (NodeJS), and ruby (experience in Ruby on Rails). Although most of my experience comes from a software engineer perspective (and development in general), I had the opportunity to learn DevOps and cybersecurity during my professional career. That helped me iterate faster, as I can develop frontend, and backend and make deployments by myself, even when IaC tools (like Terraform) are needed.

Agata S.

Test unit developer in Spain (UTC+2)

My name is Agata and I basically learned how to code by myself. I then decided to back my programming skills by getting my master's degree in IT. I have been a professional programmer for 5 years but because I really enjoy it I share my knowledge and experience after hours. I was a conference speaker at two IT conferences (about 1000 attendees each), I also started a YT channel (Agata Strojek) where I'd like to share my experiences, my passion to programming and DDD, break some stereotypes about IT and share my point of view on some topics related to tech. I really like to develop my skills after hours - I try to understand some technical decisions, frameworks or techniques that I meet in my everyday work by using them in some small projects. I am a big fan of DDD and TDD that is why I try to encourage everyone to learn something about it.

Paulo L.

Vetted Test unit developer in Spain (UTC+2)

Software engineer with 13 years of experience. Now I'm more focused on native iOS development, but I also work with native Android development (Kotlin), Flutter, backend (Node and Java/Kotlin with Springboot), and also have some experience with AWS (Lambda, S3, ECS, Elastic Beanstalk, API Gateway) and Azure. I grew the most professionally at Banco Pan. Because this was the first company where I participated in the development of a big project from scratch. I learned Scrum, participated in brainstormings with different areas of the company to gather ideas to the project, helped to build a backlog and participated in the discussions to decide what would be part of the MVP, learned a lot (hard skills) with my colleagues, made architectural decisions, and finally launched the app. On Banco Pan I had the idea (and created) the two UI libraries that were later adopted and used by all apps of the bank. I have good soft and hard skills. I learn fast. I adapt to the environment and like to participate in technical discussions and decisions that drives the project.

Iván L.

Vetted Test unit developer in Spain (UTC+1)

Currently working as a Senior QA Engineer, I found my passion for Technology at the age of 12, when cutting-edge devices were 512MB HDD pcs. Since then I've traveled a long road: from learning how to build my first computer to working in the cyber-security field, whilst watching how the field evolved around me.
