Portrait of Juan Felipe Arellano

Hi, I'm Juan

I help you convert complex requirements into scalable, compliant software. I bridge product and engineering—setting strategy, designing the architecture, and shipping reliably from MVP to scale.

About me

I'm an Engineer of Ideas—a Systems Engineer (Universidad del Norte) and M.Sc. in Computer Science (Politecnico di Milano)—who turns ambiguity into scalable, compliant, production systems. I help you convert complex requirements into outcomes by bridging product and engineering: clarifying goals, defining MVP/KPIs, designing the architecture, and orchestrating delivery end-to-end. My experience spans digital ecosystems and identity (governance, SAML/OIDC, security hardening), fintech and payments (financial operations, integrations, reconciliation), AI/RAG (private assistants, document intelligence, knowledge grounding), IoT/event-driven control, and data/ETL + BI (auditable pipelines, dashboards). This breadth lets me bring not just code, but systems thinking, stakeholder alignment, and risk-down, iterative execution you can trust—so your roadmap moves from vision to value with clean, maintainable, and measurable results. Beyond work, I served as a community leader with TECHO Colombia, and I'm co-founder of Atlético Bissa, an integration hub where locals and migrants connect through football: we start with matches and friendly leagues and grow into cultural meetups, language exchanges, and social events—because sport is the catalyst, but belonging is the real goal.
