Ownership depends on the engagement model, which we agree before work begins. A custom build can be client-owned, with the code held in a repository under the client's control, or delivered as a fully managed platform that DVSN AI owns and operates. In both cases the client retains ownership of their data, and we keep documentation and infrastructure definitions current for as long as we support the system.

Can DVSN AI take over an existing codebase?

Yes. Engagements begin with an assessment of the code, dependencies and operational risks, followed by an agreed stabilization plan before new development starts.

How is software work priced?

Discovery is fixed price. Delivery is structured as fixed-scope phases or a monthly engineering retainer, selected to match the client's budgeting model.

Which technologies do you use?

Modern, well-supported stacks. Most of our work is in TypeScript, Go and Python, with database, cloud and mobile tooling chosen to fit each system. We recommend a stack during discovery and explain the reasoning.

Do you build AI features into applications?

Yes, at the client's discretion. AI is never a requirement of our software work; we build it in only where it adds measurable value to a process. When it does, AI features and agents are delivered through the AI Solutions & Agents practice and integrated into the application, with evaluation, guardrails and cost monitoring included.

Custom software

Custom software, built and run by one team.

DVSN AI designs, builds and maintains the applications a business runs on. Because the same organization operates your infrastructure and security, every system is delivered with monitoring, access control, backups and documentation in place, and is supported after release under a defined maintenance agreement.

What is included

What we build

Full-stack application development
Web applications, internal tools, customer portals and reporting systems built on current, well-supported frameworks with a maintainable structure.
Mobile applications
iOS and Android applications for field, warehouse and customer use, including offline capture and device management integration.
Application modernization
Staged migration of ageing applications to supportable platforms without a disruptive rewrite, preserving data and daily operations.
Workflow automation and data capture
Digital forms, routed approvals, document extraction and reporting that replace manual, error-prone steps. Delivered as the Business Automation solution.
Quality assurance and testing
Automated test suites, acceptance testing against agreed criteria and performance testing before each release.
Maintenance and support
Dependency updates, security patching, monitoring, incident response and an enhancement backlog for every system delivered.

How it is delivered

How we work

Technical discovery

Every build starts with a fixed-price discovery that produces a scope, architecture and cost the client can approve before development begins.

Process and data mapping with the people who do the work
Architecture and platform selection with total cost of ownership
Written scope, phase plan, timeline and acceptance criteria
Assessment and stabilization plan when taking over an existing codebase

Engineering standards

The same standards apply to every engagement regardless of size, so every system DVSN AI delivers stays supportable, documented and ready to extend.

Source control, code review and automated testing on every change
Continuous delivery with staging environments and rollback
Infrastructure defined as code and reproducible on demand
Documentation, runbooks and architecture decisions recorded in the client's repositories

Operated after release

Delivered software is monitored, patched and backed up under the managed services practice, not handed over and forgotten.

Application and infrastructure monitoring with alerting and on-call procedures
Security patching of dependencies and platforms on a defined schedule
Backups with tested recovery objectives for application data
Enhancement backlog reviewed at scheduled intervals

Product acceleration

For organizations bringing a product to market, DVSN AI provides the engineering capacity and cloud platform to reach a first release and iterate on it.

Minimum viable product scoped to a first release with measurable goals
Cloud platform, identity, billing and analytics established from the start
Iteration cadence with release notes and usage reporting
Transition to an in-house team when the product justifies one

What sets DVSN AI apart

Built and operated by one team: The engineers who write the code also run the servers, identity and backups it depends on. There is no hand-off between a development firm and an IT provider.
Client-owned from the first commit: Source code, environments, documentation and accounts are provisioned in the client's name. Nothing is held hostage to the relationship.
Fixed-scope phases: Discovery is fixed price and delivery is phased, so each stage has a visible cost, timeline and outcome before it is approved.
