Hi, I'm Maciej Nienaltowski, a Lisbon-based AI automation and software engineer passionate about turning complex business processes into reliable, scalable automations. I design BPM-driven workflows and REST API integrations that connect ERP systems, CRMs, and cloud services, aiming to cut manual effort and improve data consistency in production. I enjoy hacking together no-code/low-code solutions, collaborating with cross-functional teams, and sharing practical insights from hackathons and freelance projects. When I'm not building automations, I chase outdoor adventures like kitesurfing, bodyboarding, and snowboarding.…Hi, I'm Maciej Nienaltowski, a Lisbon-based AI automation and software engineer passionate about turning complex business processes into reliable, scalable automations.
