      Software Development Review from Anonymous

      We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs. Talentica was brought on board to test and refine the concept from both functional and engineering perspectives, and later to build a Minimum Viable Product (MVP) aligned with the agreed specifications and constraints.

      For several years, the team was composed entirely of Talentica contractors. Since January 2022, I have been directly managing them. The Talentica team handled the admin tooling backend, which included multiple Python Flask services with Postgres and Elasticsearch. These services operated in a service-oriented architecture deployed on Kubernetes, using Istio for service mesh and Spinnaker for deployments.

      I've been working with Simform for over six months now. The engagement began with bringing our subscription management platform in-house, and we've since expanded the partnership to other projects due to their broad skill set and consistent reliability. They've gone the extra mileeven over weekends and public holidaysto help us move faster when needed. Communication and project management have been excellent, with any issues swiftly addressed. It genuinely felt like Simform was invested in our success. Having worked with similar firms throughout my career, I can confidently say Simform stands out and comes highly recommended.

      Software Development Review from Russ Makhauri

      We worked with Simform to hire a front-end engineer for our SaaS platform. The process was well-organized, and their team was professional, responsive, and efficient. They quickly identified a candidate who met our technical requirements and ensured a smooth onboarding process. Simforms communication and project management were strong throughout the engagement. They were proactive in addressing feedback and remained flexible in adapting to our needs. While there is some room for improvement in developer vetting and quality assurance, their overall service was excellent. For companies looking to scale their development teams efficiently, Simform is a reliable partner. Their structured approach, responsiveness, and commitment to client satisfaction make them a great choice. We would recommend them without hesitation.

      Ruby on Rails Review from Michael Peter Craies

      Rubyroid Labs joined our team at a time when we were starved for Ruby on Rails devs. After a very short while, the assigned team members were taking on more and more complex code and helped bolster our development outputs. Before they joined us, our average bug response time was over 2 weeks, a value that they have helped us reduce to under 8 days, with urgent tickets being resolved within a few hours. There teams' response times regarding staff movements (e.g. replacing one of our assigned devs) as well as our queries are impressive. I would definitely recommend them to any company looking to outsource their development needs.

      Tim Sanvido's Review Sourced from Google

      Okay, I don’t know why the autism speaks rules or techniques are so absurdly misunderstood. If you speak as I do there’s literally no reason a person with long time Asperger’s syndrome symptoms get treated with chaos, like if I have Asperger’s or autism, I’d be considered disabled. The autism speaks rules basically state the autistic person needs explicit rules explained without being given surprises or kind of “casual abuse”. No, this happened to me on various teams. Why? Or who is telling these rules as if that’s correct at all? I’d like to know. For years, I’m gonna I’m lucky and I hold zero animosity towards anyone. The autistic person or community might have HPA axis stress dysregulation as a feature of the condition. I can’t speak for anyone else, I’m pretty sure a stress dysregulated person needs less stress or surprises especially when it comes work. Just tell me to work one something. I was already autistic burnout when I worked here. Not trivial. I’m now realizing I can work on it. At the time I couldn’t even understand what I was doing exactly. It doesn’t spontaneously occur. Anyone that uses or loses functioning especially with facial expressions like me. It takes real work, gradual change not 100% perfect spontaneously. I get why people say it’s not real, I just need better health. I think that’s my downfall. I studied and worked on my knowledge but never my physical ability or health. I learned, thankfully. Some live and die, never knowing what happened. I’m thank I’m not, my brother was. It’s okay. It’s not for anyone to feel sorry about or tell me they sympathize or empathize. It is true though. So, before people use the crazy rules, just living and dying never knowing what caused so much damage to your life. That sucks.

      I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.
