Available to hire
Hi, I’m Jorge Aranda. I’m a Product Engineer Tech Lead at Nyxell, working remotely from Madrid. I guide the product and technology direction, researching, implementing, and adapting the solutions our company needs by closely aligning with market needs expressed through relationships with clubs that sell tickets. My background in backend and cloud engineering helps me support the team with scalable, robust systems and practical tooling.
Previously I’ve built and operated backend systems across startups and fintechs, including Fortris, Cobee, FounderNest, Fintonic, Gazella, Protecmobile, CIC, and Antartyca. I enjoy turning complex problems into simple, reliable architectures, mentoring teams, and continuously learning new technologies to drive business impact.
