Manuel Rubio is a seasoned founder and backend engineer with 13+ years building high-concurrency, highly available distributed systems using Erlang/OTP, Elixir/Phoenix, and frameworks like Django, Rails and Phoenix. He has deep telecom and messaging expertise—VoIP, XMPP, SMPP—and has repeatedly delivered scalable chat and voice platforms for companies from startups to enterprises. As founder of Altenwald he builds cross-platform mobile cores (Flutter + Go) with Elixir backends, blending hands-on systems work with product MVP delivery. Comfortable across languages (Python, Ruby, Go, JavaScript, even assembly) and databases from PostgreSQL to CouchBase, he combines DevOps instincts with architecture-level thinking. Based in Almere, Netherlands, he balances technical leadership with creative pursuits—bassist, occasional writer—and a practical focus on turning concurrent system theory into production-ready solutions.
