dZENcode is a software development and delivery company focused on complex, business-critical systems and scalable digital products. Operating since 2015, we work with startups, growing companies, and investors who need engineering responsibility, clear scope, and predictable delivery. Our 90+ in-house specialists cover the full cycle: architecture, design, backend, frontend, mobile, integrations, AI/ML automation, migrations, project rescue, scaling, and long-term SLA support. We work as an external IT department or dedicated delivery team, mainly through team outsourcing and outstaffing models. Our process is scope-driven: SoW, acceptance criteria, transparent billing, documentation, structured handover, and contract-based cooperation via a legal entity. We focus on commercial projects that need reliable execution, not one-time setup, hobby work, SEO/content-only tasks, or revenue-share models. dZENcode is ready to take ownership of delivery and support your product long-term.

Deadlines keep slipping, budgets keep growing, and the outcome becomes increasingly unpredictable. Sometimes, the team simply stops responding. At some point, the business loses control of development.

911 Team Replacement is a managed replacement service for an individual specialist, an underperforming team member, or an entire development team.

We can start working alongside your existing contractors, quickly get up to speed with the codebase and processes, retain important project knowledge, and take control of further development.

You can see us in action and compare the teams in terms of speed, quality, transparency, and results. If the previous contractor has already left, we take over the project in its current state and continue the work.

We bring in the right combination of developers, QA engineers, DevOps specialists, UX/UI designers, Project Managers, and Tech Leads. You get a complete, managed team rather than separate contractors.

This service is a good fit if:

The project is still not ready, although deadlines have long since slipped and the budget is nearly exhausted. More people are added, bugs are fixed and new changes are released in an attempt to accelerate development, yet the problems keep growing and the release is delayed again.

911 Project Recovery is a comprehensive recovery service for troubled IT projects when isolated fixes are no longer enough to move development forward.

dZENcode joins as a recovery team and examines the product in depth: we review the code, architecture, infrastructure, tasks and processes, identify the root causes behind its current state and separate critical issues from accumulated noise.

We determine what must be fixed first, what can be preserved and where the remaining resources should be focused. We remove key blockers, stabilise the product and establish a clear path towards a working release.

The most expensive development work often begins with the words, “It only needs a small fix.”

Even a minor change to an existing project can affect legacy code, architecture, infrastructure, dependencies or design. One adjustment leads to another, new bugs appear, timeframes stretch and working functionality is put at risk.

Project Audit is a review of an existing IT project before further development, expansion or handover to a new team. Its purpose is to establish the project’s current condition, uncover risks and determine a safe path for future changes.

We create a backup, deploy the project in our environment and get it running. We then examine the codebase, architecture, infrastructure, dependencies and processes. If the task involves the interface, we also assess the UX/UI and existing design system.

The audit shows what already works, what could block development, what can be preserved and which changes will be required. Based on these findings, we propose a solution, estim

A product begins when an idea gains shape, logic and a clear user journey. While it exists only as a description or in its creator’s mind, it is difficult to understand how it will work in practice or whether it is ready for development or presentation to investors.

Discovery Design is the process of designing a digital product before development begins. dZENcode turns an idea, business objective or set of requirements into a coherent solution that can be seen, explored from start to finish and agreed before any code is written.

We define the users, roles, key scenarios and business logic, then design the product structure and interfaces. We create a clickable high-fidelity prototype that allows the client to experience the future product as a user and confirm that the team has understood the idea correctly.

We define the MVP feature set, refine the scenarios and develop the concept until it is clear what needs to be built and how it should work for the user.

The same idea may be implemented in several ways. Discovery Tech explores them before full-scale development begins, tests key hypotheses and identifies the right solution for the product’s objectives, constraints and future growth.

Discovery Tech is a technical product assessment in which dZENcode examines the requirements, compares implementation options and develops a sound technical solution.

We begin with the product goals, features, user scenarios and constraints. We define the required system components, how data, external services and integrations will be handled, and the requirements for load, security and scalability.

We assess architecture and technology options, identifying dependencies, bottlenecks and technical risks. Where a key hypothesis needs practical validation, we create a PoC or technical prototype before core development begins.

The first version of a product should be launched before the budget is spent on features whose value has yet to be proven. An MVP focuses on the core purpose, reaches real users and bases future decisions on their behaviour and feedback.

An MVP is the first working version of a digital product with the minimum features needed to solve the user’s core problem and test the business hypothesis.

Development begins with design. dZENcode explores the idea, objectives and constraints, identifies the audience and defines the primary user journey. Together, we define the MVP scope, set priorities and move secondary features to later stages.

We capture the MVP in detailed designs, covering the structure, screens, states and user scenarios. Before development begins, you can see the product as a whole and understand what the first version will include and how it will work.

We design the architecture and build the backend, web or mobile application, integrations and any required AI functionali

Project for Denys K.

Nice to work with professionals, they have enough people to provide full-cycle to the development process. I am glad to find out about this company. because they do what they promise. This is not the first time we are working. Our communication is at the highest level. I recommend for cooperation. The work with CMS and custom solutions.
