Selleo has a great deal of empathy for what we are trying to accomplish and for a startup, that`s important

Selleo developed an iOS and Android mobile application using Apache Cordova. The company used an existing backend infrastructure using Ruby on Rails, and offered additional security for the applications use in financial services. Selleo continues to take on innovative projects and produce unprecedented results. Flexible and responsive, they perform a myriad of services by utilizing internal resources when needed. Their team`s communicative approach to project expectations fosters mutual trust. Selleo is almost as excited about the projects as I am.

Pros:

  • Flexible
  • Responsive
  • Excellent communicative approach

They have certainly contributed to our recognition as a market leader

Through their high-quality engineering and designs, the current website has attracted outstanding feedback from customers and industry partners alike. Selleo`s accessibility, strategic feedback, and scalable resources continue to boost productivity. I was engaged with a lead engineer named Thomas from Selleo`s team, who was responsible for the other resources on their side. For all intents and purposes, Thomas has reorganized his life around this project. We had a 6-hour time difference, and we often have calls at 2-3 p.m. Eastern Time. Thomas consistently takes part in those calls, including some that occur at 11 p.m. his time. The company treated this engagement like more than a project and a paycheck. Their team is emotionally invested in what they are doing, which, to me, is unique.

Pros:

  • Accessibility
  • Scalable resources

I was very impressed with the quality of the frontend work Selleo did, their professionalism, and their organization

I was very impressed with the quality of the frontend work Selleo did, their professionalism, and their organization They hold themselves to a high standard in all their work, whether it`s frontend, backend, or a minor design tweak. Selleo is a reliable and professional team whose superior organization makes collaboration easy. They are well-versed across the team, and they communicate well and listen to feedback. They have had a lot of training and don`t move too fast in integrating. Selleo provides outreach programs to the local high schools to try to foster new talent and spread their knowledge, which I feel is sensible and admirable.

Pros:

  • Professionalism

We are really happy to give Selleo free rein to follow their instincts when solving things.

Selleo`s team works hard, writing good code and completing all work punctually and to a high standard. Selleo is able to work on their own initiative and take responsibility for their tasks. Their team uses Pivotal and GitHub to manage the project effectively, and communicate through Slack and daily stand-ups. Selleo is very sympathetic to work with.

Pros:

  • They are easy to work with and do what I want them to do without surprises.

The products have minimal bugs, and I am happy with the quality of Selleo`s work

Selleo augments the existing development team to work on various software projects. They are currently building two web-based products, focusing on the frontend. Selleo`s team is organized and communicative, maintaining regular contact to provide project updates. They are trustworthy and eager to improve. Sometimes they need technical guidance, but their team works well and wants to build the best products possible.

Pros:

  • Organized and communicative team

Selleo delivered to the highest level of quality

Through their consistent supplementation, the integrated workforce completed tasks faster and with improved accuracy. Their outstanding price point, ability to meet all deadlines, and willingness to assimilate with the in-house staff created a more efficient workflow. Selleo was less expensive than most places in Poland, maybe because they are located outside of the major metropolitan areas. Selleo is able to give us a lower cost than their competitors.

What sets them apart is the enthusiasm and care taken on the project beyond the scope

Student feedback has been highly positive. They excelled at the interpersonal parts of software design as well as the technical elements. Selleo used daily communication to keep the project in check. Selleo`s company culture clearly nurtured an energetic and informal working environment. We have a spirit on the team that is definitely in the culture at Selleo, very similar to the type of culture I try to foster as a teacher. I look forward to our meetings; it is always fun as well as productive. Selleo`s guys are really into the project and I know they really care about its success. I believe they choose very good people and have an excellent company culture. I am very happy to be working with a company that shares my values and that has made the whole experience work very well.

Pros:

  • Enthusiasm
  • Daily communication
  • Company culture

I have been quite impressed with their work - they built a beautiful product with outstanding code

Selleo was developing a communication application that allows doctors to collaborate on cardiovascular cases while following HIPAA standards. Their resources are committed to excellence, which makes them willing to refine features until they have the best product possible. Their other strengths include Agile project management, excellent English communication skills, and consistent professionalism. I have usually struggled with making sure that international teams understood requirements, especially ones outside of English-speaking regions. Often, the wrong thing is built or not enough questions are asked. I have not seen this at all with Selleo, even though their team is based in Poland. The majority of them speaks English well. This is valuable for me since communication is key in dealing with different time frames.

Pros:

  • Agile project management
  • Excellent English communication skills
  • Consistent professionalism.

Selleo is interested in our feedback, proactively finding ways to improve

Joining the internal team, they write and review code, and provides suggestions that guide the product`s technical architecture, implementation strategies, and development processes on an ongoing basis. As a central selling point, their product attracts new clients and increases sales. The company seamlessly joined the in-house workflow, staying up to date with a variety of management tools and communicating consistently. Overall, Selleo`s team is knowledgeable, responsive, and committed to the project. Selleo`s talented developers don`t see this as just a simple project; it is clear that they care about our success. This attitude is something money can`t buy, so I appreciate their level of dedication.

We value Selleo`s opinion, and they respond by going the extra mile to optimize our product.

Able to work independently, they have become a trusted ongoing partner, capable of delivering quickly. Selleo`s industry experience and technical skill allow them to not only implement specifications but make critical product optimizations. Their customers can expect a knowledgeable, productive partner. Selleo makes everything easier on our side by taking on so many of the technical burdens. This includes everything from platform accessibility problems to new feature creation. While other agencies may simply create what we ask them to, Selleo lets us know if they have another interpretation.

Pros:

  • Technical skills

CONS:

  • Not available on weekends

They are profoundly talented in the Ruby on Rails area

Selleo provided development staff augmentation to help increase a VPN service provider`s pace and meet target deadlines. Based on a code review, Selleo gave input and made updates to enhance the UX of the API. They offered insightful and actionable suggestions to enhance the website`s UX and overall quality. Drawing from an extensive knowledge base, their developers programmed clean, high caliber code. Pleasant, skilled, and accommodating, Selleo`s team maintained a responsive and open dialogue.

Pros:

  • Skilled team

With them, the entire development process was quite open and lean.

They delivered a reliable product that is still being used today. Compared to past experiences, their team`s stands out for their involved collaborative skills and seamless workflow. Overall, we had a transparent and productive engagement. When we worked with other agencies, we had to go through several rounds of negotiations and back-and-forth discussions.

Selleo outperformed any other contractor we have worked with

Without their support, the frontend UI would not exist. The functionality Selleo implemented is reliable and communication throughout the collaboration was good. Though the team worked remotely, their dedication matched that of the in-house team.

Pros:

  • Communication
  • Dedication
  • Quality of work
