      Web Development Review from Heberto Limas-Villers

      Onix was our choice for the improvement of the company's website as part of our expansion into other states. They did a very good job of understanding my requirements and had several solutions for our needs. We had to automate a large part of the back end of the website, and they did a fabulous job with that. Communication with them was seamless, and they were very organised and diligent throughout the process. (Verified via email)

      Product Design Review from Kevin Pfeil-Schmid

      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.

      Gordon Nall's Review Sourced from Google

      Over the past five years, we have steadily expanded our relationship with Bacancy Technology, increasing the number of engineers we engage through their team. As our partnership has grown, so has the value they deliver. What has impressed me most is how effectively their engineers have self-organized, shared knowledge, and cross-trained one another. Rather than operating as individual contributors, they function as a cohesive team, collaborating on complex challenges and supporting each other's success. Over time, we have entrusted them with increasingly critical and technically demanding work. They have consistently delivered high-quality results with minimal oversight from our onshore engineering team. Their professionalism, technical expertise, and ability to take ownership have made them a valuable extension of our organization. I would highly recommend Bacancy Technology to any company looking for skilled, reliable engineering talent and a true long-term technology partner.

      Kunal Chavda's Review Sourced from Google

      We partnered with Bacancy Technology for a mid-scale development project, and the overall experience was very positive. Their team demonstrated solid technical skills, especially in understanding our requirements and translating them into practical solutions. Communication was smooth, deadlines were respected, and any challenges that came up were addressed quickly and professionally. What I appreciated most was their structured approach and the consistency they maintained throughout the project. The final delivery met our expectations, and the support they provided post-launch was equally dependable. Good choice if you’re looking for a team that’s accountable and technically capable.

      Paid $3,560 for web development—received no usable work, no deliverables, and no meaningful communication. Contractual obligations were ignored. Extremely disappointing experience.

      We recently implemented the ERP solution from MindstormSoft, and it has completely transformed the way we manage our business operations. From inventory management to financial tracking, everything is now centralized and easy to access. The system is highly customizable, which allowed us to tailor it exactly to our needs.
