      We have been working with this engineering partner for several years on the development of readout electronics for printed sensor technology, and our experience has been consistently outstanding. As one of their larger clients, we have scaled up to ten engineers working simultaneously across different disciplines, and the quality has always remained exceptional.Their team brings deep expertise in analog and digital electronics, sensor signal conditioning, embedded firmware, software development, and mechanical design. They understand the unique challenges of printed and flexible sensorsnonlinear responses, environmental drift, calibration strategies, and low-noise readoutand have repeatedly delivered robust, production-ready solutions.Their support in EMI/EMC pre-compliance and troubleshooting has been especially valuable. Their system-level understanding significantly reduced our certification risk and improved overall product reliability.Communication has always been clear, proactive, and efficient. Their engineers integrate seamlessly into our internal workflows, manage milestones professionally, and consistently deliver on time. They are flexible, fast in responding to challenges, and highly reliable during intense development phases.After years of collaboration, we can say with confidence that they are one of the most capable and trustworthy engineering partners for complex sensor electronics. We highly recommend them to any company seeking strong technical expertise, scalability, and long-term commitment.

      Tomas blanco's Review Sourced from Google

      I hired them for app consulting and development. They gave me incorrect advice on the use of certain WhatsApp and Instagram APIs, which required time-consuming verifications and significantly delayed development. They were never willing to look for solutions or alternatives, instead assigning the team to other projects and showing no intention of finishing the remaining PWA functionalities while we waited for meta approval, all to save time. I always paid them on time and in full, but they lacked human touch, cut costs, and didn't think laterally—they were like robots. I don't recommend them! I wouldn't hire them again!
