Krystian W.

Vetted Kotlin developer in Spain (UTC+1)

I am a seasoned Android developer with over a decade of experience across various roles and stages of the app lifecycle—from initial design and deployment, to ongoing growth and enhancement. I have helped launch startups, modernized legacy systems, and worked across entire tech stacks. Adept in both dynamic startups and structured corporate settings, I excel both in roles that demand a wide-ranging skill set, and deep technical knowledge.

Paulo L.

Vetted Kotlin 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.
