Secure and scalable backend for years to come

Most web and mobile applications need the backend service for proper operation. The choice of backend technology is crucial for the entire system because it affects its speed, operating costs, and reliability. A properly designed and built backend ensures transaction security and protection of its users’ data. A properly designed system should also have a well-designed and documented API so that integration with web and mobile applications is as efficient as possible.

We love algorithms and data structures

Backend is often considered a more difficult part of an IT system than front-end. We have a passion for algorithms, math, and data structures. Some of us have participated in national and international algorithmic contests and enjoy problem-solving challenges.

We value transparency and communication

We take a business-oriented approach, always keeping an eye on the client’s goals and progress while avoiding over-engineering or unproductive work.

Many engineers or agencies will jump into coding without taking the time to thoroughly understand the project. At DevsData, we think about the business perspective, listen to our clients, brainstorm, and plan the initial phases together to allow for faster iteration, gathering of feedback, and validation. No two projects are alike.

We care about more than just technology

Your business is our focus

When working on a project, we build an interdisciplinary team that aligns with your needs. The team is there to support you and to make sure that your project remains on track. Working together with our clients allows us to see beyond the code and grasp their business objectives.

DevsData LLC helps businesses cut costs and increase revenue with custom software. Our knowledge and flexibility enables us to serve both established enterprises and growing companies.

Along with deeply experienced technical specialists, our team includes people from top European business universities, alumni of elite student business programs, and accomplished consultants (BCG, EY, PwC alums).

We value transparency and communication

Working with DevsData LLC

We believe business is more about relationships than simply exchanging money for services or goods. That's why we value open communication, collaboration, transparency, and quality deliverables.

We're always open to new forms of work, but over the years, we have battle-tested the following payment options:

Flat hourly rate — we charge for every hour our developers have spent on the client’s project. Periodically (usually once a month), we issue an invoice for the last billing period. We provide a detailed receipt, so our clients know exactly what they’re paying for.

Retainer fee — similar to the hourly rate structure, but with a fixed amount of hours paid in advance. This allows us to offer a lower price–per–hour while our clients can better plan their budget.

Fixed–price — project specification and price are set in advance.

The fixed-price model simplifies budgeting, but specifications must stay consistent throughout the project. Payments are usually batched and tied to project milestones. Due to the very high risk of outdated specifications, we suggest this agreement only for particular projects.

Fixed–price — it is the least flexible form of agreement where specification and price are set in advance. It makes it very easy to plan a budget, but specifications must stay consistent throughout the project. Payments are usually batched and tied to product milestones. Due to the very high risk of outdated specifications, we suggest this agreement only for particular projects.

We enjoy working in a tight feedback loop, which is why we usually integrate directly with our client’s team. We take part in the same stand–up meetings, execute planning and development together, and are part of the same chat rooms. We keep our clients informed via the same communication channels they are already using internally like email, Slack, Telegram, WhatsApp, or IRC. We want our clients to have constant insight into what we're working on and keep them updated on any progress. Regular video meetings are arranged, typically on a weekly basis.

Every agreement carries some risk; we always strive to mitigate these risks for our clients. We want our collaboration to be seen as an investment, not as a cost,and we include various guarantees and SLAs in our client agreements.

We are unwavering in our commitment to security and quality assurance

Through the implementation of ISO 27001 and other certifications, we ensure that our software development services align with the highest industry standards, ensuring security, reliability, and compliance.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
