      AI Development Review from Ivan Pasichnyk

      We brought Diffco in to deliver the AI and computer vision components for one of our clients, an image generation startup. Because the work sat inside our own client relationship, we needed a partner we could trust to operate at our standard without us managing them day to day - and that is exactly what we got. Diffco owned the technical approach, built the computer vision and AI layer, and delivered the full scope in three months, on schedule. The engineering quality was high, they raised the right questions early instead of late, and they handled the confidentiality the project required without us having to chase it. After delivery they stayed on to support the system, which mattered to us as much as the build itself. When you subcontract a technical project inside your own client relationship, the risk is that the partner makes you look bad. Diffco did the opposite. They've earned our trust and we'd work with them again.

      Diffco built a complex, production-grade AI agentic system and backend for our client's fintech platform owning architecture, AI/ML components, and AI agents in a security- and compliance-sensitive environment. They delivered on time and within budget, communicated proactively, and operated like part of our own team, taking ownership and suggesting better solutions throughout. Deep AI/ML and senior backend expertise. We'd happily work with them again.

      Product Design Review from Chris Milner

      UXReactor helped us with a UI/UX research process, which included in-person interviews where they walked users through unboxing, connecting, and using the features of our smart air conditioner. From there, the team took the findings and produced a report for us to make improvements to our app and increase our activation rates. In addition to the report, UXReactor also redesigned some parts of our app using Figma.The project required a very iterative process, so we required more than one discovery call to get started. In fact, they didn't just work with me; we also integrated our consumer marketing insights team to identify participants. We also collaborated with them to figure out how to recruit the right users based on our target customer profiles.Additionally,UXReactor recruited participants for us, going through their database to find actual users. Then, they brought a researcher and a designer to interview all the participants on-site in their location. That was actually a challenge because we're a remote team, but we needed a physical location to show the actual air conditioner to the participants.After the interviews, UXReactor worked with us to go through the results and the report's structure. We had multiple revisions to ensure that we were pulling out the insights I wanted to find on it. After the report was complete, they actually delivered it to our overseas team, doing a presentation that included the insights and recommendations.

      Product Design Review from Dhirendra Kumar

      The objective was to create a safety release which would activate at certain weights and fit into an already existing design. Porticos was able to create a strong, lightweight and reusable buckle which fit perfectly into the design both functionally and visually. Their involvement improved the overall safety of our therapeutic equipment, and allowed us to develop another complete product line of similar products with other applications.

      UI/UX Design Review from Kamil Qui

      The project scope was to to refresh the UX and visual design.The project lead really helped . I was taking care of a lot of other things, so I appreciated getting weekly updates from them. They detailed the work they did and then outlined the next items on the list. They brought up potential roadblocks in advance, making sure wed still meet deadlines.UXReactor worked very closely with us, so they were an extended team from my perspective. I could call upon and engage them in discussions, and we had daily standups.They followed a systematic methodology, and that helped us go through the process of doing user research, collecting feedback, and combining that with the existing product features. Using that, we were able to create a framework that allowed us to continue development.

      This company is illegitimate. Someone close to me was offered a job without an interview, and there have been numerous red flags. They sent a fake check (from a closed bank account and signed by “Long Live”) to buy needed materials for the job. Luckily we were smart enough not to provide any information or click on any email links.Stay away! I have tried numerous times to make contact with someone legitimate in the company but haven’t heard anything.

They presented me with 3 resources in less than 10 days, my team successfully interviewed them and they started on our project a mere 18 days after I first contacted them on their website. I can only hope their work will be as good as their staffing is efficient.

      I've worked as a contractor for several firms over the years. TopDevz really stands out above the others. They stay deeply involved throughout the project, maintaining regular communication with both client and contractor. This level of engagement really changes the nature of the project, making it a team-oriented approach rather than a simple contractor placement. This helps the project keep on track and insures that the contractor will keep busy. The people at TopDevz are all very friendly and helpful and I've been very happy working there.
