Federico A.

I bring 20+ years of experience building software and solving real-world engineering problems. I learn quickly, adapt to new technologies and environments, and take ownership of problems from idea to solution. I particularly enjoy complex backend and performance challenges. I like evaluating technologies and approaches based on their trade-offs, not trends. In this AI-driven era, I also look beyond the technical side: cost, scalability, complexity, and whether a solution actually makes business sense for the company's current stage. I care about building reliable, maintainable software and making practical decisions that balance technology and business needs. I'm comfortable working independently, communicating across teams, and getting up to speed quickly. I can work internationally through my US-based Kayak Consulting LLC, so invoicing and contracting are not an obstacle.
