Two development packages decide where the AI runs while we build: leading cloud tools or privately hosted models. Both apply across all four capabilities, with the same engineering, UI/UX, QA and DevOps standards. ### Private / Local AI Engineering *AI-powered software delivery in a controlled processing environment.* For projects with specific processing requirements. We set up and evaluate privately hosted models, agree the access boundaries, then design, build, test and release your software inside that environment. - A senior engineer as your HR for AI, managing the agents - Privately hosted models, evaluated on your own tasks - Infrastructure setup with agreed access boundaries - Expert engineering, UI/UX and QA - Controlled releases with review and rollback - Optional ongoing management of the private models and infrastructure.

We run the workflow and take responsibility for delivery, so you never manage coding agents yourself. - A senior engineer as your HR for AI, managing the agents - AI-assisted codebase analysis and planning - Implementation and refactoring, reviewed by engineers - Tests and documentation with every change - Architecture, UI/UX, QA and DevOps behind each release - Continued development, maintenance, QA and operations, as scoped.

Claude Code & Codex: New builds, modernization and ongoing development where approved cloud AI tools fit your policies. - **AI processing environment:** Private / Local AI: Open-weight models hosted privately, on infrastructure you control or that we set up for the project. Claude Code & Codex: Claude Code and OpenAI Codex, processed by each provider under the account and settings approved for your project. - **Setup and infrastructure:** Private / Local AI: Model selection and evaluation, hosting and access setup, scoped before development starts. Claude Code & Codex: No AI infrastructure to build: we bring an established, reviewed workflow into your repositories. - **Data and access arrangements:** Private / Local AI: Access boundaries, logging and network rules agreed and documented with you. Claude Code & Codex: Access limited to the repositories and data the work needs; provider terms and settings confirmed with you. - **Expert oversight:** The same in both: a senior engineer acts as HR for AI, directing and reviewing all AI-assisted work, and designers, QA and DevOps own their parts of every release. - **Ongoing management:** Private / Local AI: Maintenance, QA and operations as scoped, plus optional management of the private models and infrastructure. Claude Code & Codex: Continued development, maintenance, QA and operations, as scoped. The package decides where AI processing happens while we build. Where your finished application runs is planned separately, in your cloud account or another environment agreed for the project. ## Specialist services - [Web & Mobile App Development](https://npcoding.ca/services/application-development/): Web apps, mobile apps and customer portals built around the way your business actually works.

What you get is continuity, visibility, and a team that remains responsible after launch. ## How NPCoding works 1. **Discover & design:** Workshops, user journeys and prototypes. AI helps us synthesize research and explore options quickly; designers and your team decide what to build, and QA turns it into acceptance criteria. 2. **Architect & plan:** Engineers define the architecture and the data and security boundaries, then break the work into tasks small enough to delegate and review. AI helps map existing code and the impact of changes. 3. **Build with AI agents:** AI agents (Claude Code and Codex, or privately hosted models, depending on your package) implement scoped tasks, refactor, and draft tests and documentation. Your HR for AI, a senior engineer, assigns their work and reviews every change before it merges. 4. **Review & validate:** QA validates against the acceptance criteria with automated suites and exploratory testing, independently of the code that implemented them. Sensitive changes get a security review. 5. **Release, operate & improve:** DevOps releases through a controlled pipeline with approvals and a rollback path, then monitors production. What we learn from real use shapes the next iteration. Testing, security and operations work runs through every stage, not just the end. ### Who does what - **AI agents:** Help us understand codebases, implement and refactor scoped changes, draft tests and keep documentation current. - **HR for AI:** A senior engineer who assigns the agents' work, sets what they may touch, reviews every change and owns the technical decisions. - **Designers & QA:** Assess the product as people will use it, and validate it independently of the code that implements it. - **DevOps:** Establish a controlled path into production: pipelines, approvals, monitoring and rollback. ## Frequently asked questions ### Which capability do we need? Tell us what you're trying to build and we'll recommend the mix. Most projects combine software and app development with UI/UX, QA and DevOps, and each of those is also available on its own. ### Can we engage you only for QA or DevOps? Yes. Both are available as independent engagements for software built by another team, and both are built into every NPCoding development project. ### How do you keep AI-assisted work correct and safe? Every change is reviewed by an engineer, tested against acceptance criteria by QA and released through a controlled pipeline with approvals and a rollback path. AI accelerates the work; it doesn't approve it. ### Do we have to choose a development package? Only for development work. Design-only, QA-only and DevOps-only engagements don't need one. When we build or change software for you, you choose between Claude Code & Codex Engineering and Private / Local AI Engineering, or we recommend one after the first conversation. ### Do you still offer dedicated developers? Yes. Dedicated engineers can join your team full-time, typically within a week, backed by our code review, QA and delivery oversight. ### How much does a software project cost? Every project is scoped individually, with a detailed estimate after discovery. Assessments are scoped by the size and risk of the system, and ongoing partnerships by the responsibilities you need covered. --- NPCoding · AI-powered software & app development · Toronto, Canada · support@npcoding.com · https://npcoding.ca/contact/
