AI Development Review from Oleg Sotnikov

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.

Mobile App Development Review from Julia Platova

We partnered with Diffco for a comprehensive software development project aimed at delivering a mobile application and backend system for our client. The goal was to create a seamless, secure, and scalable solution within a 4-month timeline and $50k-$200k budget. Diffcos team was highly professional from start to finish. They handled everything: UI/UX design, backend architecture, API integration, and deployment. After the launch, they continued to support us with maintenance and performance optimization. The application received positive feedback and has proven stable and scalable. Were highly satisfied with Diffcos expertise, commitment, and ability to deliver real results.

eCommerce Development Review from Jutamas Puengpinit

We engaged SoftLoft, Inc. to enhance our e-commerce platform, which is critical for delivering our modular IoT solutions efficiently across emerging markets. As Mandom Corporation (Thailand) Limited operates in a fast-paced production and tech environment, we needed a development team that could understand both our industry-specific needs and the technical depth required to support our operations. Our goal was to refine our platform's functionality, improve system stability, and enable easier configuration and ordering of IoT devices for clients. SoftLoft delivered far beyond our expectations. Their team, consisting of a Business Analyst, four Magento developers, and two testers, approached the project with remarkable professionalism. From the outset, the Business Analyst played a pivotal role in capturing our requirements in detail and transforming them into clearly defined tasks. This laid a strong foundation for the developers to implement complex features with precision, and for the QA team to conduct thorough, issue-free testing. The project involved building a new interface for configuring device packages, optimizing backend operations for better order management, and delivering detailed documentation to support ongoing maintenance. Every deliverable was executed with care, on time, and with full transparency. What stood out most was SoftLofts commitment to quality and their responsiveness. Communication was smooth and proactive throughout the project. Their attention to detail, flexibility in accommodating adjustments, and clear documentation ensured a seamless experience for our team. The improvements they implemented significantly reduced internal friction and enhanced client satisfaction. Our experience with SoftLoft was outstanding. They brought structure, clarity, and excellence to every phase of the project. We would highly recommend them to any business seeking a reliable and capable development partner for e-commerce solutions.

eCommerce Development Review from Lev Peysekhman

I had the pleasure of working with this development team on launching an eCommerce store for our healthcare retail business in Thailand. The project was complex building a Magento-based platform integrating over 10 different systems, including product and order management, plus financial tools. They also developed some really smart features, like a dynamic questionnaire that recommends vitamins based on user input, and a secure portal for doctors to manage prescription orders. What impressed me most was their professionalism and adaptability. We had a lot of stakeholders with varying needs, tight deadlines, and even changing regulations that required quick adjustments. Despite all this, the team remained agile, communicated clearly, and delivered exactly what was promised on time. Their technical expertise ensured seamless integration across all systems, which made the entire operation much smoother. Thanks to their work, we launched a fully functional store that improved customer experience and compliance with healthcare regulations. I highly recommend this team to anyone looking for a dependable, skilled partner for complex eCommerce projects.

eCommerce Development Review from Rob Duxter

I'm more than satisfied in my experiences with Soft Loft. I've worked with them for a few years now, on several projects from eCommerce sites (Magento, Shopify, custom) and even apps and information architecture requirements from tech stack evaluation/selection to DNS setup and management. Every team member I've engaged with from their Executives, to Business Analysts to Project Managers, QA and Developers or Information Architects .... total Pros. Whether a small project under $20k or large over $200k - the quality and professionalism is rock solid. Thank you Soft Loft. Keep it up!!

Staff Augmentation Review from Sergey Novik

Were developing an internal image processing tool for our design team and needed two machine learning engineers, since our core developers were busy with other client projects. We required extra hands familiar with Python and computer vision, so after a developers market review, we hired them from SumatoSoft. The SumatoSoft developers joined our team and were able to swiftly adapt to our workflows, which resulted in them delivering the working models well before our hard deadline. Communication was straightforward throughout the engagement. We had video calls and exchanged brief text updates on a weekly basis. The delivered code is clean, and pull requests are well-documented. I appreciate that they pushed back on a few of our initial architecture ideas. They challenged our original approach and proposed a better method for handling the model weights. We plan to bring them back for the next phase of development.

SumatoSoft is the firm to work with if you want to keep up to high standards. The professional workflows they stick to result in exceptional quality. Important, they help you think with the business logic of your application and they don’t blindly follow what you are saying. Which is super important. Overall, great skills, good communication, and happy with the results so far.

We are notably satisfied with the upshot. PMs and development team was very devoted to the tasks and encouraging. We had a stringent and fixed deadline. And we got it just in time! KitRUM helped us to create an entire software that absolutely meets our requirement. They had presented the system in a short-term after putting their hands on it. They also provide support after developing this software. We have a different project now and certainly will work with KitRUM again.

Software Development Review from Daisy Skot

KitRUM made a variety of development services: conception, coding, and QA, which means almost a full software package for our company. We needed to develop a few tasks, for example, a desktop app for our store, a cloud app for administration and supervision, and a portable app for end customers. However, we had an in-house team, which is not enough for this project. So we had to find a dedicated team that could deliver all we needed. We found KitRUM as a top-notch software development company

Software Development Review from Daria Stolyar

We hired Altoros engineers as an essential extension of our client-facing internal teams. This was a tough decision because our reputation as a brand depends on the overall efficiency of our processes and we needed to make sure all risks are mitigated when it comes to delivery. Altoros has not let us down. Together with Altorosians we successfully deployed a number of tough and technologically complex projects on time. So our collaboration is certainly set to continue.

Ruby on Rails Review from Greg Lipper

In my 30 years in the software business, I have never had as positive an experience with an outsourced development services provider as I have with Altoros. Each Altoros engineer we have worked with has been strong technically, estimated development times accurately, completed projects on time, and delivered code and projects with high quality. Beyond that, they have helped improve our thinking and approach with suggestions and ideas that were better than the spec of instructions we supplied.
