Who am I?
Hi, I’m Airán 👋
I’m a software developer who enjoys moving across disciplines whenever the problem calls for it. I have worked in data, web product, backend, infrastructure, and internal tools; to me, the stack is a means rather than an identity.
I started by studying web application development and expanded that foundation through a Full Stack bootcamp. Since 2020, I have worked at LeanMind in very different contexts: data processing at Clarity.ai, a confidential technology platform, invoice-system modernisation at Voxel, internal initiatives, and currently full-stack development for TechnyFarma.
I’m especially interested in turning complex systems into software that a team can understand, maintain, and improve. Beyond code, I write, share what I learn, and join conversations about how to build better.
