What I'm looking for

I am looking for opportunities that foster growth, collaboration, and innovative problem-solving.

I'm Kalle Suomala, a dedicated full-stack developer with over three years of experience specializing in Ruby on Rails applications. My journey in software development has been driven by a passion for creating meaningful solutions to real-world problems. I have honed my skills in building, scaling, and maintaining full-stack web applications using Rails, PostgreSQL, and modern frontend technologies like Hotwire, Turbo, and Stimulus.

In my current role at Pikasiirto, I serve as a key developer on an instant money transfer platform that caters to over 200,000 users. My contributions include full-stack development, RESTful API integrations, and payment system integrations, which have significantly improved system scalability and responsiveness. I am committed to writing clean, efficient code and continuously advancing my technical skills through hands-on projects and self-learning.

My educational background includes a two-year program at Hive Helsinki / École 42, where I was trained in a practical, project-based environment. This experience has equipped me with the skills necessary to thrive in the tech industry, and I am motivated to leverage my expertise in new and challenging projects.
