Make the complex understandable
Important decisions should be explainable in simple words.
Santiago, Chile · Software Engineering & Technical Leadership
Abel
Fernández
Software engineer building clear, fast, and durable web platforms. I bring together architecture, product thinking, and technical leadership.
Outside of work, I’m an amateur photographer drawn to mountain biking, long hikes, road trips, and time in nature. Most importantly, I’m learning every day to be the best father I can be to my son, Matías.
A way of working
Technology changes. Clarity, judgment, and care for the details endure.
My career has taken me from university research in Cuba to remote collaboration with teams in Germany and the United States, and later to building products in Chile. At every stage, I have aimed for the same thing: understand the problem well and leave a better foundation for the people who continue the work.
Experience
From the classroom to the platform
More than twelve years building web products and systems, guiding technical decisions, and helping other engineers grow.

Universidad de Holguín
University Professor
Learning by explaining
I started by teaching web development and object-oriented programming while building software to process and manage biomedical data. Teaching taught me to turn complex problems into ideas that other people can understand and use.

Taking product work beyond the classroom
Alongside teaching, I worked remotely from Cuba with a Berlin-based team building web and mobile products for electric-bike rentals. It was my first experience delivering software across countries, time zones, and product surfaces.

Growing into full-stack product engineering

How I approach the work
A few ideas that have stayed useful across teams, technologies, and product stages.

Design for whoever comes next
Code, documentation, and processes are part of the product too.
03
Measure before optimizing
Performance and reliability start with observation, not assumptions.
